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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQuick-change system allows hole saw and pilot bit swaps without extra tools\u003c\/li\u003e\n\u003cli\u003eDual-position collar locks securely for one-handed operation\u003c\/li\u003e\n\u003cli\u003eNo-seize collar stays engaged during drilling to prevent hole saw lock-on\u003c\/li\u003e\n\u003cli\u003eFits all standard threaded hole saws with no adapter required\u003c\/li\u003e\n\u003cli\u003eAccepts hole saws from 1-1\/4 inches to 6 inches in diameter\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank fits standard keyed and keyless drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with all threaded hole saws in the 1-1\/4 inches to 6 inches diameter range.
