Starrett 65620 Hole Saw 1-1/2 in Carbide Tipped

Product Description

The STARRETT 65620 is a carbide-tipped hole saw designed for cutting clean, accurate holes in a range of hard and abrasive materials. It measures 1-1/2 inches in diameter and delivers a cutting depth of 1-5/8 inches. The toothed cutting edge runs at a constant pitch pattern, providing consistent cutting performance across material thicknesses. This hole saw is suited for trade professionals working in HVAC, plumbing, electrical, and general construction who need a reliable tool for penetrations through dense substrates. It ships as a single unit and does not include an arbor.

The STARRETT 65620 is well-suited for residential and light commercial applications where penetrations must be made through fiberglass, Formica, masonry brick, MDF, plaster, or suspended flooring. It is commonly used by HVAC technicians running duct penetrations, electricians drilling knockout holes, and plumbers routing pipe through composite or masonry surfaces. The 1-1/2 inch diameter is a standard size for conduit and small-diameter pipe pass-throughs.
