Starrett 00434 Hole Saw 1-3/4 in Hss Variable Pitch

Product Description

The STARRETT 00434 is a high speed steel (HSS) hole saw with a 1-3/4-inch cutting diameter and a 2-inch cutting depth. Built with a toothed cutting edge and a variable pitch pattern ranging from 4 to 6 teeth per inch, it is designed to cut cleanly through metal, steel, and wood. The variable pitch reduces vibration and helps prevent tooth stripping during cuts. At 0.5 pounds, the saw is lightweight and sized for use in tight spaces. It is a replacement-style saw intended for installation and service trades where consistent, repeatable hole sizing is required.

This hole saw is suited for residential and light commercial applications where tradespeople need to cut uniform holes through multiple material types in a single tool. Electricians, plumbers, and HVAC technicians use saws in this diameter range for routing conduit, pipe, and ductwork penetrations through wood framing and light-gauge metal. The 2-inch cut depth accommodates standard framing lumber and sheet metal of typical wall and cabinet thicknesses.
