While looking for a random orbital sander, you may need to compare the Dewalt 6421 vs 6423. Having worked with Dewalt tools and random orbital sanders for years, I have much to contribute to this topic. The most important factors you should look for in these tools include power, speed, dust extraction, weight, cost, and design. I recommend that you tailor these items to your needs. In this article, we will learn more details about these tools.
Overview of the Dewalt 6421
The Dewalt dwe 6421 is a 5-inch random orbit sander with a 3 Amp motor. The orbital sander spins the pad at a maximum speed of 12,000 OPM. The sander has a counterweight design that reduces vibration during operation. That ensures you a comfortable experience when you are handling the electric sander.
The sanding machine has rubber in its critical parts. You hold it from different positions that are convenient. The hand sander has a shorter height. You have visibility of the activities taking place. The improved dust switch protects your sander and your health system from dust.
That makes the hand sander last longer. The dust collection system is effective. And the one-handed locking dust bag makes the process easy to control. The dust port is connectable to universal dust collectors. This allows you to attach it to vacuum systems. The Dewalt 6421 weighs up to 3.4 pounds. The package includes the Orbit sander, dust bag, and a user manual. A skirt around the disc makes it efficient in dust collection.
- No vibration
- Shorter height
- An improved dust collection system
- The dust bag needs regular emptying
Key Features of the Dewalt DWE6421
Dust collection system
The hand sander has improved dust–sealed switch that protects the machine from ingesting dust. The dust port fits the DWV010 or the DWV012 dust collectors. An extendable dust extraction system that includes vacuum systems is more efficient. You connect the port to a 1-1/4inch horse or use the DWV9000 Universal Quick Connector. A vacuum cleaner will give you the best dust management feature. That does not mean the dust canister is insufficient, but it tends to lose some dust particles when the sander lacks a horse. The dust bag fills up, and it needs regular emptying.
Power and speed
The hand sander has a fixed speed of 12,000 OPM, which might disadvantage a user who prefers speed variance. However, that keeps your speed limit constant in different materials. It helps you master your speed since you have a single speed. The 3amp motor is powerful enough to speed the pad at such a high speed.
The top part and the rest of the body have an anti-slip grip. That allows you to hold the sander with comfort and confidence. You have control over when the sanding machine is operating. The anti-slip grip also prevents your hand and body from a low vibration. In that manner, you hardly feel fatigued after a long work day.
Hook and loop system
The hook and loop system makes sanding pads easy and quick to change. When attaching the sanding pads to the sanding disc, you must match the holes from both sides and press firmly. A clicking sound will assure you that they are correctly attached.
The sanding disc is 5 inches in diameter. It is round in shape and ideal for straight and flat surfaces. It does not fit in tricky places such as corners.
Overview of the Dewalt 6423
The Dewalt DWE 6423 is a 5-inch variable-speed random orbit sander. It has a 3 amp motor produces 8,000 to 12,000 Orbits per minute. The speed variance allows you to control the speed depending on the type of material you are working on. The separate counterweight makes the machine withstand the vibration.
You do not feel the vibration in your arms. That gives you a comfortable experience without being irritated. The dust bag allows you to use one hand. In that case, the rubber grip makes handling the machine comfortable. The low-profile design allows the user to get closer to the sanding device. That feels comfortable even if you are short or tall. Trying to reach out to a tall machine is straining, and you will not be comfortable.
It is easy to remove and clean. Your environment stays dust-free. The sander is ideal for woodwork. It is a good sander for the money. The machine has an orbit diameter of 3/32 inches. The dust port is a bit difficult to connect to the hole. Using a Dewalt vacuum system makes it better. However, rubber tubing to the vacuum improves the system. The sander runs smoothly, with the slightest vibration that gives you a professional and flawless finish.
