Hole Saw Accessories

Replace worn or damaged parts or expand your tool's capabilities with these arbors, pilot bits, extensions, hole saw shields, ejection springs, and more.


Sometimes called mandrels, arbors attach a hole saw to a drill chuck. Arbors can also hold a pilot bit that helps center and stabilize the hole saw when starting the cut.

Ejection Springs

Rather than manually clearing the plug from the hole saw, use these ejection springs to automatically eject the plug after cutting. The springs are installed over the pilot bit and are compressed as the cut is being made. When the hole is complete, the spring expands and pushes the plug out of the hole saw.
