If you’re spending $500–$700 on your first serious table saw, you’ve almost certainly landed on these two. The Delta 36-725 lives at Lowe’s; the Ridgid R4512 lives at Home Depot. Both are 10-inch, 13-amp contractor-hybrid saws with cast iron tops. Both accept a dado stack. Both roll on wheels. And both have devoted owner communities who swear by them.
But they aren’t the same saw. The differences that matter are in the fence system, dust collection, motor wiring flexibility, and a few quirks that only emerge after years of shop use. This guide draws on firsthand owner accounts from woodworkers who have run these saws for four to six-and-a-half years, plus both official operator manuals, to give you a genuinely useful comparison — not just a feature list.
Note on availability: The Ridgid R4512 is no longer sold new at Home Depot. Ridgid’s current equivalent is the R4560. The Delta 36-725 remains available new at Lowe’s at time of writing. Used R4512 units are widely available on the secondary market, which is where many buyers still find them — and where much of the real-world owner feedback originates.

The Fence: Where These Saws Actually Diverge
Of all the things you’ll use on a table saw, the fence is the one you interact with on every single cut. Get it wrong and you get bad cuts — or worse, kickback.
Delta 36-725 Fence
The Delta ships with a T-square 3-point locking rip fence that runs on steel rails. Owners who run the saw regularly rate it highly: one woodworker with two years of shop use called it “the best fence you can get on one of these saws in this price range” and noted he chose the Delta over competitors specifically because of it. Another owner with four years on the saw praised its precision but flagged a real-world issue: the front clip allows slight movement, which means the top and bottom of the fence can drift out of parallel if the rails aren’t lubricated and the fence isn’t locked with care. The fix — keeping the rails well-waxed and checking squareness before each rip — is minor but worth knowing before you buy.
Ridgid R4512 Fence
The Ridgid fence is aluminium with front and back clamping on both rails. Multiple long-term owners praise how easy it is to slide and how well it holds once locked. The two-point rail contact is actually a stricter design than the Delta’s, and several users note it can be dialled in with a square and relied upon — though one owner who has used the saw for six-and-a-half years noted that it can fail to self-square on lock-down, requiring a quick front-and-back measurement to confirm parallelism. A misaligned fence is one of the primary causes of kickback, so this is worth checking during initial setup regardless of which saw you buy.
Edge: Delta 36-725, marginally, for its reputation among owners who prioritise fine furniture work. The Ridgid fence is fully competitive at this price tier, but the Delta’s T-square design has the slightly stronger track record for consistent fence squareness.
Dust Collection: The Most Significant Practical Difference
This is the area where the two saws diverge most sharply — and where the Ridgid wins decisively.
Ridgid R4512: 4-Inch Port
The R4512 ships with a 4-inch (10.2 cm) dust port attached to a funnel-shaped chute beneath the blade. Gravity drops sawdust down into the chute, which hooks directly to a standard dust collector hose. Owners who run the saw in active shops — including those with dedicated one-horsepower dust collectors — report effective capture during ripping sessions. The 4-inch port is the industry standard for shop-level dust collectors, meaning you can hook it up without reducers or adapters.
Delta 36-725: 2.5-Inch Port
The Delta’s 2.5-inch (6.4 cm) dust port is the most consistently criticised feature across all owner reviews. One owner who tried both a shop vac and a dedicated dust collector called the performance “ridiculously bad.” Another noted sawdust blowing out the front, the back, and the bottom simultaneously. A third owner — who has used the saw for four years on everything from treated lumber to hardwood — admitted the dust collection was poor enough that he removed the chute entirely and routed sawdust directly out the bottom of the saw. A zero-clearance throat plate (which reduces debris falling through the kerf) helps, but the underlying port size is a genuine constraint.
This matters beyond tidiness. The CDC’s National Institute for Occupational Safety and Health (NIOSH) classifies hardwood dust as a Group 1 carcinogen when inhaled over extended periods. If you’re cutting hardwoods regularly — walnut, maple, cherry — in an enclosed garage or basement shop, effective dust collection is a health issue, not just a housekeeping one. The Ridgid’s 4-inch port gives you a meaningful advantage here.
Edge: Ridgid R4512, clearly.
Mobility System
Both saws roll on integrated wheels, but the systems are engineered very differently — and one is considerably better.
The Ridgid R4512 features a foot-pedal-activated retractable caster system. Press the pedal, the casters deploy, the 266-pound (120.7 kg) saw lifts off the floor and can be moved with two fingers. Lower it again and it sits flat on four feet with no wobble. This system is genuinely excellent — multiple owners flag it as one of the best features on the saw, noting that buying a mobile base for a comparably specced saw would cost around $150–$200 separately.
The Delta 36-725 has a simpler wheel-and-foot lever design. You tip the saw back onto its rear wheels, which works fine but requires more physical effort and a bit of floor space to manoeuvre. At 197 pounds (89.4 kg), the Delta is significantly lighter, which partly compensates. For small garages where the saw needs to be wheeled out to park a car, the Ridgid’s caster system is the superior solution.
Edge: Ridgid R4512.
Motor and Voltage: A Useful Ridgid Advantage Few People Know About
Both saws run a 13-amp motor, but the Ridgid R4512 can be wired for 240V operation. According to the official Ridgid operator manual, the conversion is covered in the assembly instructions and involves re-wiring the motor leads — a job for someone comfortable with electrical work, but not an exotic modification. Running a saw at 240V doesn’t change the motor’s peak horsepower, but it does allow the motor to draw lower amperage for the same output, reducing heat buildup on long ripping sessions and improving voltage stability if your shop wiring is marginal.
One long-term Ridgid owner converted to 240V early in his ownership and reported noticeably faster power-up response and smoother performance under load through six-plus years of use. The Delta 36-725 is 120V only.
Edge: Ridgid R4512 for shops with 240V capacity or plans to wire one.
Cast Iron Table and Wing Levelling
Both saws use cast iron for the main table surface and stamped/pressed steel for the extension wings. Cast iron is the right material here — it’s heavy enough to dampen vibration, machines flat, and accepts a paste wax or TopCote surface treatment that lets workpieces glide smoothly. Both saws showed no meaningful warping or flatness issues in long-term owner accounts, with one minor caveat: neither saw’s wings are cast iron, and getting them precisely coplanar with the main table during assembly takes patience.
Ridgid owners consistently flag wing levelling as the most time-consuming part of assembly — one reviewer noted it took him longer to level the wings than to assemble the rest of the saw. Delta owners report a similar experience, particularly on the right-side extension. This isn’t a defect; it’s the nature of stamped steel wings on either saw. Budget an extra hour for this step and use a reliable straightedge across the joint.
One practical option popular in both owner communities: replace the factory steel wings with a shop-made MDF or melamine panel, which can be shimmed to perfect coplanarity and also provides a built-in surface for mounting a router table — a common upgrade for both saws.
Safety Features: Both Saws Are Properly Equipped
Both the Delta 36-725 and the Ridgid R4512 ship with the three safety components that matter most on a table saw: a riving knife, a blade guard, and anti-kickback pawls.
The riving knife is the most important of the three. Unlike a fixed splitter (found on older saws), a riving knife rises and falls with the blade, maintaining a consistent gap in the kerf during through-cuts. This prevents the workpiece from pinching the blade — the primary mechanical cause of kickback. The Ridgid manual specifies that the riving knife must be used for all through-sawing operations and can be repositioned to two heights for different cut types. Multiple owners of both saws report never making a cut without the riving knife in place, even when removing the blade guard for visibility.
The anti-kickback pawls on both saws are spring-loaded teeth that allow the workpiece to travel forward through the blade but dig in if the wood reverses direction. The Ridgid’s pawls mount on either side of the riving knife and are independently adjustable.
One thing worth knowing from the Ridgid manual: the blade on the R4512 runs at 3,450 RPM at no load, but speed decreases under load or with lower supply voltage. If your shop wiring is marginal (long extension cords, shared circuits), blade speed can drop enough to affect cut quality and increase kickback risk. The Ridgid manual recommends a minimum 14 AWG extension cord for runs under 25 feet (7.6 metres) and a 12 AWG cord for runs up to 50 feet (15.2 metres).
Additional safety gear worth adding to either saw:
- Push stick — the stock push sticks on both saws are serviceable. The Micro Jig GRR-Ripper is widely used by owners of both saws and adds downward pressure on the workpiece in addition to lateral push force, which is especially useful on narrow rips.
- Featherboard — holds the workpiece against the fence during a rip cut. Essential for consistent, safe narrow ripping.
- Zero-clearance throat plate — reduces tear-out on delicate work and prevents small offcuts from dropping into the saw. The Ridgid accepts aftermarket plates readily; the Delta’s 8-inch steel plate is less commonly stocked but can be made from PVC sheet.
Blade Upgrades: Don’t Run the Stock Blade
Neither saw ships with a blade worth keeping. Both come with a combination blade adequate for initial setup, but owners of both saws replace it quickly. The most commonly recommended aftermarket blades among owners of both saws:
- Diablo D1050X — 50-tooth combination blade. One Ridgid owner ran this for four-plus years and considered it his reference blade. Approximate retail: $40 USD / $60 CAD.
- Irwin 50-tooth finishing blade — recommended by a Delta owner for fine cabinetry work. Good performance on hardwoods at a lower price point.
- CMT combination blade — another long-term owner favourite on the Ridgid, particularly for mixed ripping and crosscutting sessions.
If you’re using either saw primarily for ripping hardwood — walnut, maple, cherry — a thin-kerf blade is worth considering. Thin-kerf blades remove less material per pass, reducing the load on the motor, which matters on a 13-amp saw where power isn’t unlimited. The trade-off is slightly less stability in the blade plate, which can introduce minor deflection on very thick stock.
Dado Stack Compatibility
Both saws accept an 8-inch dado stack up to 13/16 inches (20.6 mm) wide — confirmed in both official manuals. This is an important spec because many entry-level contractor saws have shorter arbors that can’t safely accommodate a full dado stack.
The Ridgid R4512 ships with a dedicated dado throat plate slot, and aftermarket dado inserts are widely available (typically $15–$20 on Amazon). The Delta 36-725 accepts dado stacks through the same 5/8-inch arbor, though the wider stock throat plate means you may want an aftermarket zero-clearance dado insert for cleaner results. One Delta owner runs the Freud SD208 8-inch dado stack and reports excellent results for dadoes, grooves, and rabbets.
Router Table Integration: A Practical Space-Saver
A popular modification for both saws — especially in single-car garage and basement shops — is mounting a router table into the right-side extension wing. The factory steel wing is removed and replaced with a router table insert, effectively turning one machine footprint into two tools.
Owners of both saws have successfully integrated the Bosch RA1181 router table into the extension wing space. One Ridgid owner who made this modification described it as fitting “almost perfectly,” needing only 3/32-inch (2.4 mm) spacers to sit flush with the aluminium wing rail. A Delta owner installed a router table into his right wing as the first upgrade after purchase and called it an “absolute space saver” for his small shop.
The Ridgid’s extra extension rail length on the right side provides slightly more mounting flexibility for a router table insert. Both saws accommodate it; the Ridgid gives you a bit more room to work with.
Long-Term Reliability: What Six-Plus Years of Use Reveals
The most useful data on either saw comes from owners who have run them for multiple years, not from unboxing reviews. Here’s what surfaces across extended-use accounts:
Ridgid R4512 Long-Term Issues
- Blade height mechanism pin failure — one owner who has used the saw since 2016 reported that a small retaining pin in the blade-raising wheel mechanism has sheared multiple times over the years. The pin can be replaced with a finish nail as a temporary fix, but it’s a recurring maintenance issue not documented in the manual. Not all owners report this; it may be unit-specific.
- Wheel rust — the three bottom wheels are mild steel and will rust in humid environments (Ontario, coastal climates, unheated garages). Functional but cosmetically deteriorates over time. A light coat of paste wax on the wheels slows this.
- Riving knife lever stiffness — the locking lever on the riving knife can become tight over time and may require channel-lock pliers to release for blade changes.
- Ridgid Lifetime Service Agreement (LSA) — Ridgid’s LSA covers repairs but requires you to bring or ship the saw to a service centre. For a 266-pound (120.7 kg) table saw, this is effectively unusable. Research local Ridgid service centres before buying if warranty coverage matters to you.
Delta 36-725 Long-Term Issues
- Screws loosening — multiple owners flag screws across the assembly working loose over time. A thread-locking compound on key fasteners during initial assembly prevents this.
- Bevel gauge inaccuracy — the built-in angle gauge for blade tilt is not precise on either saw. Both owner communities recommend a digital angle gauge (the Wixey WR365 is the most commonly cited) regardless of which saw you own.
- Miter gauge — the stock miter gauge on both saws is widely considered inadequate for precise crosscuts. A third-party miter gauge or a shop-made crosscut sled is a near-universal upgrade among serious users of either saw.
- Dust collection degrades over time — because the port is only 2.5 inches (6.4 cm), partial blockages from accumulated sawdust inside the chute worsen collection performance. Regular cleaning of the internal chute is required.
Who Should Buy Which Saw
Buy the Delta 36-725 if:
- You prioritise a precise, reliable fence system out of the box for fine furniture and cabinetry work.
- Your shop has a standard 120V circuit and you don’t need 240V capability.
- You already have a shop vac and don’t mind supplementing with a broom — or you plan to upgrade the dust collection independently.
- You want a new saw with manufacturer backing and a clear return path.
- The lighter weight (197 lb / 89.4 kg) matters because you’re working in a space with stairs or tight access.
Buy the Ridgid R4512 if:
- Dust collection is a priority — the 4-inch (10.2 cm) port connects directly to a standard dust collector without reducers.
- You have or plan to wire a 240V circuit and want the motor conversion option.
- The foot-pedal caster system is important — you need to frequently move the saw in and out of a tight space.
- You’re buying used and can get a well-maintained unit at a meaningful discount.
- You want slightly more rip capacity and cut depth at 90°.
Accessories Worth Adding to Either Saw
Both saws are platforms — the stock configuration is a starting point, not an ending point. The upgrades most commonly made by long-term owners of both saws:
- Quality aftermarket blade (Diablo D1050X or equivalent) — immediate improvement in cut quality and finish.
- Crosscut sled — the stock miter gauge on both saws is not accurate enough for fine woodworking. A shop-made sled with Micro Jig Miter Slider runners takes an afternoon to build and transforms precision crosscutting.
- Zero-clearance throat plate — reduces tear-out and prevents small offcuts from dropping into the mechanism.
- Digital angle gauge (Wixey WR365) — the built-in bevel gauges on both saws are unreliable. A digital gauge takes the guesswork out of bevel cuts.
- Dado stack — if you build furniture with shelves, cabinets, or drawers, a dado stack (the Freud SD208 is a consistent owner recommendation) pays for itself quickly.
- Push stick upgrade — the Micro Jig GRR-Ripper provides push force and downward pressure simultaneously, which standard push sticks don’t.
Final Verdict
These two saws are close enough that the right answer depends on what you’re optimising for — which is exactly why a feature-list comparison doesn’t settle it.
If dust collection and mobility are your top priorities — particularly if you’re in a basement or garage shop where sawdust has nowhere to go — the Ridgid R4512 is the better buy. Its 4-inch (10.2 cm) dust port, foot-pedal caster system, and 240V wiring option make it the more capable shop machine.
If fence quality and precision are your top priorities — particularly if you’re building furniture, cutting joinery, or working with hardwoods where accuracy directly affects fit — the Delta 36-725 earns its reputation. Owners who prioritise fine work consistently cite the fence as the reason they chose the Delta and the reason they’d choose it again.
For a first serious saw where you’re buying new, the Delta’s continued availability at retail gives it a practical edge. For buyers comfortable with the used market, a well-maintained R4512 at a meaningful discount is a compelling find — provided you verify the blade-height mechanism, check the fence for squareness, and confirm the wings level correctly before money changes hands.
Either way: budget for a quality aftermarket blade, plan to make a crosscut sled, and buy a digital angle gauge before you need it. Those three additions will improve your results far more than the difference between the two saws.
