Overview of Foredom LX
These permanent magnet motors are specifically developed for high torque/low-speed applications for activities like stone setting, wax modeling, and pearl drilling.
The LX is a 1/10 HP ball bearing motor that delivers full power and torque from start-up to 5,000 rpm. It works well with the Foredom drill press. It works well with the #15 and #15D Hammer Handpieces.
The SR is the most common Foredom Flex Shaft. It is a 1/6 HP universal flexible shaft machine that rotates at rates of 18,000 RPM in both forward and reverses spin. The SR motor combines the essential attributes that customers seek in a single motor: power, reversibility, reliability, and versatility.
Features of Foredom LX
The LX Series Foredom Flex Shaft is a low-speed, high-torque motor (maximum speed 5000 RPM) designed for low-speed/high-torque applications, including stone setting, jewelry wax grinding, carving, and pearl drilling. It’s also an excellent flex shaft motor for hammer handpieces. The permanent magnet, ball bearing motor that it replaces is more potent than the Foredom “L” series motor. Foredom’s No. 30 handpiece and TXR foot control are present. Also available without a handpiece but with foot control. The voltage is 115 volts.
The Features of Foredom SR
The Foredom SR series is Foredom’s most popular flex shaft tool; most customers choose it because it is so versatile. The Foredom H.30 chuck-style handpiece offers tool shank sizes 0″ to 5/32″ (0–4mm) for drilling, stone setting, polishing, and other activities. Within the Foredom SR series, there are a variety of kits for different users, such as jeweler kits, woodworker kits, and available kits. Be aware of this if you want to utilize the tool for a particular task.
Foredom’s FCT-1 solid-state electronic foot pedal is slip-resistant and allows you to set your speed from low to high.
This 43-piece accessory kit includes spinning bur and tool holder mounted points, wire and bristle brushes, sanding drums, 3M radial bristle discs, various buffs, polishing wheels, compound, mandrels, and flex shaft oil. The engine and foot control are covered by a two-year warranty, while the handpiece has 90 days of cover. Because of the flexible shaft and rapid detachment, switching between most Foredom handpieces is quick and easy (which does not support H.30H, H.44HT, and H.28H). The Foredom SR series will benefit the majority of flex shaft tool users. It is designed for the typical user and is well-suited to various precision jobs.
Price comparison for Foredom LX and SR
Hanging rotary tool for Foredom SR Polishing Flexible Shaft Machine The price of a motor is usually approximately $400. 1 x Foredom SR 220V Hanging motor, 1 x hanging motor, 1 x electronic foot control, 1 x chuck key, 1 x handpiece, 1 x manual, and 1 x flexible shaft are present in the box. Drilling, polishing, burring, milling, slotting, cutting, and wood and bone carving are all possible with this equipment.
Foredom LX Motor series, on the other hand, has the following characteristics: low speed, high torque motor that is best for stone setting, wax modeling, and hammer handpieces. It costs between $300 and $400
Power comparison – Foredom LX vs SR
The most popular motor, the SR MOTOR, provides plenty of power and speed for most chores without stopping or slowing down under a typical load. It can move forward and backward. Running in reverse is useful for symmetrical grinding and carving, extending the life of some abrasives and giving you more control over your tool if you’re left-handed. The following are some of the qualities that make it superior to Foredom LX:
- HP 1/6*
- Extremely fast – up to 18,000 RPM.
- Run in both forward and reverse directions, which is helpful for symmetry, releasing stuck drills, left-handed users, and extending the life of various rotating equipment.
- Motor with universal ball bearings.
The LX MOTOR, on the other hand, is more specialized. The 1/10HP LX motor is Foredom’s most powerful motor; it is slow but powerful. It has full strength from the start at 500 RPM to the maximum speed. It’s suitable for slow-speed drilling, wax modeling, stone setting, chisel carving, etc. The following are some of its distinguishing characteristics:
- Strong – at low speeds, the most potent Foredom motors.
- Has a maximum rotational speed of 5,000 RPM. As a result, it is slower than the SR, running at less than a third of the rate. And this is beneficial when utilizing a Hammer or Carving handpiece (the H.15 and H.50), which may get damaged at faster speeds.
- There is no reverse rotation on this motor. It runs forward only.
- Permanent magnet motor.
The Foredom Jewellers Pendant LX Motor is a long-lasting high torque/low speed hanging motor with a foot pedal speed control. The LX series motor is a popular choice for stone setting, wax modeling, and pearl drilling because it provides more power and control with its high torque/low-speed combination.
The new Foredom SR motor is ideal for continuous production in jewelry manufacturing activities, increasing performance and power. Except for the H.30H, H.44HT, and H.28H versions, the flexible shaft has a quick-detach function and accommodates any Foredom handpiece. A forward or reverse motion switch is present on the powerful 1/6hp ball bearing 18,000rpm motor. For a longer motor life, lower the operating temperature.
When to use Foredom LX instead of Foredom SR?
The LX is excellent for low-speed burr work; it’s not quite fast enough for polishing mops or rubber abrasives — the latter, but you’ll be there for a while. The LX is a low-speed pendant motor with a maximum speed of 5000 rpm, making it suitable for stone setting, pearl drilling, wax carving, and other applications requiring high power and control.
When to use the SR instead of the Foredom LX
Flex shaft motors of the Series SR series are 1/6 HP, run forward and reverse at speeds of 18,000 RPM, and provide all of the power and speed needed to complete most jobs. And this is the most commonly used motor with a maximum speed of 18000 rpm. The SR has two options for attaching your handpieces to the flexible shaft: an essential tip or a slip joint. Both types allow for easy handpiece changes, with the critical end simply slotting in and the slip joint having a lever.
The LX motor is available in two versions. Both of these systems are foot-operated, similar to a dental drill, which you will find much more convenient than having to turn on and off a button or slider. You may also acquire a desktop speed control, a dial, to help limit the RPM to a preset pace, ideal for stone setting with a hammer handpiece.
