DEWALT Rapid-Load DAH9912PBM Hole Saw Arbor, 1/2 in Shank, 1-1/4 to 6 in Dia Bit, Hex Shank

The DeWALT RAPID LOAD® quick change hole saw accessory system allows for changing hole saws and pilot bits without additional tools. The collar clicks between two positions for saw and pilot bit change and stays in position for one-handed application. The no-seize collar stays engaged while drilling to resist the hole saw locking onto the arbor. DeWALT RAPID LOAD® arbors fit with all threaded hole saws, no adapter required.
