Starrett 00442 Hole Saw 2 in Hss Variable Pitch

Product Description

The STARRETT 00442 is a high speed steel hole saw designed for cutting clean, precise holes in metal, steel, and wood. With a 2-inch saw diameter and a 2-inch cutting depth, it handles thick stock and deep-bore applications that shallower saws cannot reach. The toothed cutting edge runs a variable pitch pattern at 4 to 6 teeth per inch, reducing vibration and improving chip clearance across a range of materials. Plumbers, electricians, HVAC technicians, and general tradespeople use this saw wherever a round cutout is required in structural or finish materials.

This hole saw is suited for residential and light commercial trade work. Common applications include drilling cable and conduit pass-throughs in metal panels, cutting pipe penetrations in wood framing, and making access holes in steel enclosures or junction boxes. The 2-inch depth of cut allows it to pass through doubled framing members and thicker composite panels without stalling or losing engagement. It is sold individually and fits standard arbors that accept this saw diameter.

• 2-inch cutting depth handles doubled framing members and thick panels
• High speed steel construction provides hardness and wear resistance on metal and wood
• Variable pitch 4 to 6 TPI toothed edge reduces vibration and improves chip evacuation
• Compatible with metal, steel, and wood material applications

Compatibility

Designed as a replacement-style hole saw for standard arbors accepting a 2-inch diameter saw body, suitable for use in metal, steel, and wood cutting applications.

Installation Notes

A licensed electrician, plumber, or HVAC technician typically installs hole saws as part of a rough-in or penetration task. Secure the workpiece firmly before starting the cut, and use the appropriate arbor and pilot drill for the saw diameter. De-energize any circuits and shut off water or gas supplies before cutting into areas where utilities may be present. Follow applicable NEC, IPC, or IFGC requirements for penetration clearances and fire-stopping after the hole is made.
