The DEWALT DW660 is a 5-amp, corded rotary saw designed for fast, accurate cutouts in drywall, plywood, and trim. With a no-load speed of 30,000 RPM and a slim, ergonomic body, the DW660 gives you the power and control you need for production work.
At the heart of the DW660 is a 5.0-amp motor that spins at 30,000 RPM, allowing you to plunge into drywall without tearing the paper. The tool-free collet system lets you change bits in seconds, and the dust-sealed switch keeps drywall dust out of the switch mechanism for reliable operation.
If you ever find your DW660 collet stuck, don't panic. Unplug the tool, then use the supplied wrench to turn the collet nut counterclockwise. Apply penetrating oil if needed and allow it to work for a few minutes. Tapping the wrench lightly with a hammer can help break the grip. Keep the collet and spindle clean to avoid recurrence.
Replacement collets for the DW660 are available in 1/8-inch and 1/4-inch sizes. For drywall work, pair the saw with a high-speed spiral bit; the 30,000 RPM motor makes clean, wobble-free cuts. The included 1/8-inch and 1/4-inch collets cover most bit shank sizes.
The slim body reduces fatigue during repetitive cutting, while jam-pot construction protects the armature from impacts. The turn-on/bump-off switch lets you shut off the tool by accidentally bumping the switch, a nice safety touch.
If you're a drywall finisher, carpenter, or DIY homeowner, the DEWALT DW660 rotary saw is a dependable addition to your kit.

With 30,000 RPM of no-load speed, the DW660 tackles drywall, thin plywood, and laminate without bogging down.
Swap bits in seconds using the integrated wrench—no chuck key needed. The 1/8-inch and 1/4-inch collets cover all common accessories.
The dust-sealed switch prevents fine drywall particles from entering critical components, extending the life of the switch.
At only 4 lbs and with a slim grip, the DW660 is easy to control for detailed cuts.
Clean the collet regularly with compressed air, reduce heat buildup by using sharp bits, and never overtighten the collet nut. If a collet sticks, a few drops of penetrating oil and a light tap from a mallet usually free it.
The DW660 accepts any standard 1/8-inch or 1/4-inch shank rotary bits, including drywall bits, router bits, and grinding stones.
First, unplug the saw. Use the supplied wrench to loosen the collet nut. If it's stuck, apply a penetrating oil around the nut and tap it gently. Make sure no debris is jammed between the collet and shaft.
Yes, collets are replaceable. Use replacement collets from DEWALT or generic 1/8-inch and 1/4-inch rotary tool collets.
Yes, its 30,000 RPM motor and slim nose make it ideal for cutting drywall and other sheet materials.
No, it runs at a fixed 30,000 RPM.
This little saw is a gem. It cuts drywall without tearing. The collets change in seconds. Runs very fast.
I use it to cut openings in drywall. It's precise and easy to control. The 1/4 collet handles my router bits too.
Spins up fast and cuts clean. Tool-free collet is the best. I've cut 100s of outlets with it. No complaints.
Works good.
Very handy.
I have been doing drywall for 40 years. This saw is reliable. The collets are easy to swap. It's powerful enough for any job. I've worn out two of these over the years.
It vibrates a bit but cuts fine.
This saw is a lifesaver. Cutting outlets is so much faster now. My boss even bought one.
Good for small projects.
I've used it for cutting drywall, laminate, and plastic. It's versatile. The collets are simple to change. I like the trigger lock.
Does the job but is noisy.
The high RPM makes clean cuts in wood and drywall. The 1/8 collet is perfect for laminate. The tool-free change is quick.
Good saw for the price.
I'm a DIYer and this makes me look like a pro. It's light and easy to maneuver. No more manual cutting. Very happy.
It's a reliable rotary saw.
