Dewalt DAH9938PBM Rapid Load Hole Saw Arbor 20 Pack

Product Description

The DEWALT ACCESSORIES DAH9938PBM is a Rapid Load quick-change hole saw arbor sold in a pack of 20. It accepts hole saws ranging from 9/16 inch to 1-3/16 inch in diameter and uses a 1/2 inch shank for chuck compatibility. The collar snaps between two positions — one for hole saw changes, one for pilot bit changes — allowing single-handed operation without reaching for a wrench. A no-seize collar stays engaged during drilling to prevent the hole saw from locking onto the arbor, reducing downtime and bit damage. Electricians, plumbers, and carpenters who run high volumes of hole saw cuts will find this arbor system a practical shop consumable.

This arbor is suited for residential and light commercial work where frequent hole saw swaps are routine — rough-in wiring runs, pipe penetrations, door hardware installs, and similar repetitive drilling tasks. The tool-free change system is designed for jobsite use where speed and continuity matter. Each pack contains 20 arbors, making it appropriate for stocking multiple drills on a crew or maintaining a supply of fresh arbors across a fleet of tools. The arbor threads directly onto all standard threaded hole saws with no adapter required.

Installation Notes

Install into any 1/2 inch chuck drill or drill driver before attaching the hole saw. Confirm the chuck is fully tightened before drilling. Always power down and disconnect the drill from its power source or battery before swapping hole saws or pilot bits. Follow applicable OSHA and site safety requirements for rotary tool use.
