Starrett 65643 Hole Saw 5 in Carbide Tipped Toothed

Product Description

The STARRETT 65643 is a 5-inch diameter carbide-tipped hole saw designed for cutting through hard and abrasive materials that standard bi-metal saws struggle with. With a cutting depth of 1-5/8 inches and a constant-pitch toothed edge, it delivers consistent, controlled cuts in dense substrates. The carbide tipping resists wear far longer than standard high-speed steel on tough applications. This hole saw is an unabrided tool for contractors, remodelers, and trade professionals who regularly cut through masonry, fiberglass, or composite panels on the job.

This hole saw is suited for residential and commercial applications involving hard or layered materials. Typical use cases include cutting rough openings in suspended floors, penetrations through plaster walls, knockouts in MDF panels, and holes in fiberglass or Formica surfaces. Electricians, plumbers, HVAC installers, and general contractors will find this saw useful when routing pipe, conduit, or duct penetrations through walls, ceilings, and floors made of masonry brick, plaster, or composite sheet goods.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with rotary cutting tools and appropriate PPE.

Verify that the arbor is properly seated and locked before operating the drill. Follow applicable OSHA guidelines and local safety codes for tool use on the job site.
