3-1/4" Hole Saw Assembly with Arbor & Pilot Bit

One Clean Cut, Every Time — No Ragged Holes, No Do-Overs

Every boot and termination in a ventilation run starts with a hole, and a sloppy one costs you time you will never get back patching drywall. This 3-1/4" hole saw assembly cuts a clean, round opening through drywall, subfloor, and framing so your boot seats square and flush the first time.

It arrives ready to work: the hole saw, the arbor, and the pilot bit, all assembled. The hex shank locks into a standard drill or impact driver, and the centering pilot bit keeps the cut from wandering when you start it overhead on a ceiling.

Key Features

3-1/4" Cutting Diameter — Sized for clean openings at duct terminations.

Hex Shank Arbor — Chucks into standard drills and impact drivers without slipping.

Slotted Barrel — Side slots let you pop the plug out quickly and clear dust between cuts.

Ready to Use — Ships assembled, no separate arbor purchase required.
