Starrett 65637 Hole Saw 4 Inches Carbide Tipped

Product Description

The STARRETT 65637 is a carbide-tipped hole saw with a 4-inch cutting diameter and a 1-5/8-inch cutting depth. It features a toothed cutting edge and a constant pitch pattern, making it well suited for cutting through tough, abrasive materials that would quickly wear down standard bi-metal blades. This hole saw is sold as a single unit without an arbor, so a compatible arbor must be sourced separately before installation. It is used by contractors, tradespeople, and skilled DIYers who regularly cut holes in non-metallic building materials.

The STARRETT 65637 is designed for use in a wide range of non-metallic substrates commonly encountered in residential and light commercial construction. Suitable material applications include fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring. It is a practical choice for electricians, HVAC technicians, and general contractors who need to cut clean, accurate holes through wall panels, ceiling materials, and flooring systems during rough-in or retrofit work.

Compatibility

Designed for cutting fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring. This saw does not include an arbor; verify arbor compatibility before use.

Installation Notes

Install the hole saw onto a compatible arbor before use, and confirm the arbor is fully secured before operating the drill. Wear appropriate eye and respiratory protection when cutting masonry, fiberglass, or MDF, as these materials generate fine particulate dust. Use a variable-speed drill and maintain moderate speed and steady pressure to avoid overheating the carbide tips. Disconnect power to the drill before changing or inspecting the saw.
