Dewalt Accessories DAH9912PBM Hole Saw Arbor 1/2 in Shank

Product Description

The DEWALT ACCESSORIES DAH9912PBM is a Rapid Load quick-change hole saw arbor designed to speed up bit and saw swaps on the job site without requiring additional tools. The arbor accepts hole saws ranging from 1-1/4 inches to 6 inches in diameter and uses a 1/2-inch shank for chuck compatibility. A dual-position collar clicks securely between hole saw mode and pilot bit change mode, allowing one-handed operation during transitions. The no-seize collar stays engaged throughout drilling to prevent the hole saw from locking onto the arbor mid-cut. Electricians, plumbers, HVAC techs, and general contractors working with hole saws will find this arbor well suited to high-volume drilling applications.

This arbor is suited for residential and commercial trade applications where frequent hole saw changes slow down workflow. It is compatible with all standard threaded hole saws, requiring no adapter. Typical use cases include running conduit, pipe, and duct penetrations through framing, drywall, and similar substrates. The package contains 20 units, making it appropriate for stocking service vehicles or tool cribs. Each unit features a 1/2-inch shank that fits standard keyed and keyless chucks.
