Starrett 00427 Hole Saw 3/4 in Hss Metal Wood

Product Description

The STARRETT 00427 is a high speed steel hole saw designed for cutting through metal, steel, and wood. With a 3/4 inch saw diameter and a 2 inch cutting depth, it handles tasks that require clean, accurate through-cuts in a range of materials common to electrical, plumbing, HVAC, and general trade work. The toothed cutting edge runs at a variable pitch of 4 to 6 teeth per inch, allowing it to manage both thin-walled and moderate-thickness stock. Electricians, pipefitters, and general contractors reach for this size when punching knockouts, running conduit, or boring holes for pipe penetrations in light-gauge steel and wood framing.

This hole saw is suited for residential and light commercial trade applications where a 3/4 inch opening is required. Typical uses include boring holes in electrical panels, junction boxes, wood studs, and sheet metal. The 2 inch cutting depth gives it enough reach for standard dimensional lumber, steel box walls, and similar substrates. It is sold as a single saw body without an arbor, making it compatible with standard hole saw arbors that accept 3/4 inch saw sizes.

Key Features

• 3/4 inch saw diameter for precise, consistent hole sizing
• 2 inch cutting depth accommodates standard lumber and steel enclosures
• High speed steel construction provides hardness and heat resistance during metal cutting
• Variable pitch toothed edge at 4 to 6 teeth per inch reduces chatter and improves cut quality across materials
• Suitable for metal, steel, and wood applications in a single tool

Compatibility

Designed as an OEM-style replacement hole saw body compatible with standard arbors that accept 3/4 inch diameter hole saws. Sold as a single unit without an arbor included.

Installation Notes

Hole saws are installed by licensed electricians, plumbers, and HVAC technicians using a compatible drill motor and arbor. Secure the workpiece and ensure power tools are properly grounded before use. When cutting metal, apply appropriate cutting fluid to reduce heat buildup and extend saw life. Disconnect all electrical power to panels or enclosures before cutting into them.
