Starrett 65642 Hole Saw 4-3/4 in Carbide Tipped

Product Description

The STARRETT 65642 is a carbide-tipped hole saw designed for cutting through tough non-metallic materials. It carries a 4-3/4 inch saw diameter and delivers a cutting depth of 1-5/8 inches per pass. The toothed cutting edge with a constant pitch pattern provides consistent, controlled cuts with reduced chipping. This hole saw is well suited for contractors, HVAC technicians, and plumbers who need clean, accurately sized holes through surfaces like fiberglass panels, plaster walls, MDF, and suspended flooring. The carbide-tipped construction extends service life compared to standard bi-metal saws when cutting abrasive materials.

The 65642 is intended for use in applications involving fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor assemblies. It is commonly used during rough-in work where penetrations through wall boards, ceiling panels, and subfloor materials are required. This saw is not arbored, meaning an appropriate arbor must be selected separately to match your drill chuck size. Typical users include HVAC installers cutting duct openings, plumbers creating pipe penetrations, and general contractors working with composite or masonry surfaces.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotary cutting tools. Ensure the drill and hole saw assembly are fully secured before operation, and verify the arbor is properly torqued to the saw body per the arbor manufacturer instructions. Always wear appropriate eye and respiratory protection when cutting masonry, fiberglass, or composite materials. Disconnect power to the drill before changing or inspecting the saw.
