The WILLIAMS COMFORT PRODUCTS 3832-89 is a carbide-tip hole saw sized at 3.5 inches in diameter, designed for cutting clean, precise holes in a range of materials encountered in trade work. Carbide-tipped teeth extend tool life compared to standard bi-metal designs, making this saw appropriate for repetitive cuts in harder substrates. It is sold as a single unit and suits electricians, plumbers, HVAC technicians, and general contractors who need a reliable hole saw for rough-in and fixture work.
This hole saw is suited for applications where a 3.5-inch opening is required, such as pipe penetrations, conduit routing, electrical box rough-ins, and duct or fitting cutouts. The carbide-tip construction makes it a practical choice for use in wood, drywall, fiber cement, and some plastic materials common in residential and light commercial installations.
Designed as a standard 3.5-inch hole saw compatible with arbors and mandrels accepting industry-standard hole saw threading. Verify arbor compatibility with your drill before installation.
Hole saws are typically installed by electricians, plumbers, and HVAC technicians during rough-in phases. Ensure the drill arbor is fully secured and rated for the saw diameter before use. Wear appropriate eye and hand protection when cutting. Follow applicable local codes for penetration sealing and fire stopping when cutting through rated assemblies.
