The DEWALT DW1803 Quick Change Mandrel (sometimes called a quick change arbor) is built for fast, secure hole saw changes. Its spring-loaded collar automatically engages drive pins to help prevent hole saws from locking onto the mandrel, and the hardened steel body is tested through 15,000+ cycles for jobsite toughness. The recessed combination-head set screws make centering bit changes quick and easy.
The DW1803 is designed for use with DEWALT hole saws and other standard hole saws that match its spring-loaded collar. For the best fit, choose hole saws with a compatible rear mounting thread or bayonet slot (check the hole saw backplate for compatibility). If you’re replacing a worn pilot bit, the improved pilot bit design is also compatible with this mandrel.
Pull back the spring-loaded collar, insert the hole saw, and release. No wrenches or set screw adjustments needed. The collar locks the saw firmly in place, reducing the chance of the saw spinning free under load.
Hardened steel construction and double set screws with a recessed combination head allow quick centering bit changes. This mandrel is built to hold up through thousands of cycles, so you can rely on it day after day.
The DW1803 features a hex shank that fits standard drill chucks, and it's compatible with a wide range of quick-change hole saws. It's a versatile addition to any pro's or DIYer's toolbox.

Changing hole saws on a traditional arbor means digging out a set screw, finding the hex key, and trying not to drop the tiny part inside the work area. The DW1803 turns that into a one-handed operation.
With use, a traditional set-screw mandrel can bind or loosen. The DW1803's spring-loaded collar holds the saw firmly, and the drive pins engage automatically when you push the saw onto the mandrel.
For most DEWALT hole saw kits, this mandrel is the missing link. Pair it with a set of hole saws and a standard drill, and you can cut clean holes in wood, drywall, and metal.
Keep the collar clean and free of sawdust. A drop of oil on the moving parts keeps the spring action smooth. Avoid letting the mandrel overheat during heavy use.
The DW1803 is designed for DEWALT quick-change hole saws and other hole saws that fit its spring-loaded collar. Always check the hole saw's backplate for compatibility.
Pull back the spring-loaded collar, insert the hole saw, and release the collar. The drive pins engage automatically to secure it.
Yes, the spring-loaded collar automatically engages drive pins to help prevent the hole saw from locking to the mandrel.
The improved pilot bit design is compatible with this mandrel and provides longer life in all materials.
This mandrel is great. Changing hole saws is now a snap.
I had to get a replacement because I lost my original. This one works as expected. The quick change is convenient.
I'm not a fan of newfangled things, but this is solid. It made my hole saw jobs easier.
Works well.
I've used this on multiple jobs and it hasn't let me down. The spring-loaded collar is strong and holds the saw securely. I appreciate the hardened steel construction. Worth the money.
