Williams Comfort Products 3830-20-VIP Bimetal Holesaw

Product Description

The WILLIAMS COMFORT PRODUCTS 3830-20-VIP is a bimetal holesaw packaged in an industrial single-unit format. Bimetal construction combines a high-speed steel cutting edge with a flexible alloy steel body, giving the saw the hardness needed to cut through sheet metal, wood, plastics, and light conduit without tooth breakout. At 25/32 inches in diameter, this holesaw is sized for trade applications that require precise, smaller-diameter penetrations. It is sold individually and suited for use by electricians, plumbers, and HVAC technicians who need a reliable cutting tool for panel knockouts, pipe penetrations, and conduit entry points.

This holesaw is used in both residential and light commercial service work where controlled, clean hole cuts are required through a variety of substrates. Typical applications include cutting knockout holes in electrical enclosures, creating pipe pass-throughs in framing and drywall backing plates, and boring conduit entry points in metal panels. The 25/32-inch diameter fits common trade rough-in and penetration sizing needs encountered during installation and retrofit work.

Installation Notes
