Williams Comfort Products 3830-70-VIP Bimetal Hole Saw

Product Description

The WILLIAMS COMFORT PRODUCTS 3830-70-VIP is a bimetal hole saw sold in an industrial pack configuration. Bimetal hole saws combine a high-speed steel cutting edge with a flexible alloy steel body, allowing the blade to withstand the stress of cutting through sheet metal, wood, plastics, and similar materials without cracking or premature tooth wear. At 2-3/4 inches in diameter, this saw is sized for conduit knockouts, junction box cutouts, and pipe penetrations that are common on HVAC, plumbing, and electrical rough-in work. The industrial pack format is suited for shop or job-site stocking where multiple units are kept on hand.

This hole saw is used across trade applications including electrical panel and enclosure work, HVAC sheet metal penetrations, plumbing rough-in through wood framing, and general mechanical contracting. The 2-3/4 inch cut diameter fits common trade tasks where a standard knockout punch is not practical. Electricians, plumbers, HVAC installers, and general mechanical contractors are the primary users of this tool.

Key Features

Compatibility

Designed as a standard bimetal hole saw for use with compatible arbors and drill drives used in electrical, plumbing, and HVAC trade applications. Verify arbor compatibility before use.

Installation Notes

Installation is performed by electricians, plumbers, and HVAC technicians using a standard hole saw arbor and corded or cordless drill. Ensure the workpiece is securely clamped before cutting to prevent binding or kickback. Follow applicable NEC, IPC, or IFGC penetration and firestopping requirements when cutting through rated assemblies. Replace the saw when tooth wear results in increased cutting resistance or reduced cut quality.
