Williams Comfort Products 3830-105-VIP Bimetal Hole Saw

Product Description

The WILLIAMS COMFORT PRODUCTS 3830-105-VIP is a bimetal hole saw sold in an industrial pack configuration. Designed for cutting clean, accurate holes in a variety of materials including wood, plastics, and thin metals, this hole saw is built for the demands of trade work. The bimetal construction combines a high-speed steel cutting edge with a flexible alloy steel body, providing durability and resistance to tooth breakage during extended use. At 4.125 inches in diameter, it handles larger penetrations common in HVAC duct work, electrical rough-in, and plumbing pipe access holes. It weighs 1.014 pounds and is sold as a single unit.

This hole saw is suited for residential and light commercial trade applications where a reliable, larger-diameter cut is needed. Electricians use this size for panel knockouts and conduit entry points. HVAC installers use it for duct collars and equipment knock-outs. Plumbers rely on similar diameter saws for drain and supply line penetrations through framing and subfloor material. The industrial pack format makes it a practical choice for technicians who want a ready-to-use saw without sourcing additional arbors separately.

Installation Notes

Hole saws of this type are installed by licensed electricians, plumbers, and HVAC technicians using a compatible arbor and a corded or cordless drill with sufficient torque.
