Starrett 00488 Hole Saw 1-1/4 in Hss Toothed Edge

Product Description

The STARRETT 00488 is a high speed steel hole saw designed for cutting clean, accurate holes in metal, steel, and wood. The saw features a 1-1/4 inch diameter cutting edge and a 1-5/8 inch cut depth, making it suitable for through-hole work in standard material thicknesses. The toothed cutting edge runs at a constant pitch of 5.5 teeth per inch, delivering consistent chip removal and a clean bore. Electricians, plumbers, HVAC technicians, and general contractors reach for this size when routing conduit, pipe, or cable through framing, sheet metal, and similar substrates.

This hole saw is used across residential and light commercial applications where a 1-1/4 inch hole is required. Common install scenarios include routing electrical conduit, plumbing lines, or low-voltage cabling through wood studs, metal brackets, and thin steel panels. Its compact cut depth of 1-5/8 inches makes it well matched to standard framing members and sheet goods without the need for a deep-cut arbor setup.

Key Features

• 1-1/4 inch saw diameter for standard conduit and pipe rough-in applications
• 1-5/8 inch cut depth accommodates typical framing and sheet material thicknesses
• High speed steel construction resists heat buildup during extended cutting cycles
• Constant pitch at 5.5 TPI delivers smooth, consistent chip clearance
• Toothed cutting edge compatible with metal, steel, and wood substrates

Compatibility

Designed as an OEM-style replacement hole saw for use with standard arbors accepting 1-1/4 inch hole saws across residential and commercial trade applications.

Installation Notes

Installation is performed by licensed electricians, plumbers, or HVAC technicians depending on the application. Secure the workpiece firmly before cutting and use appropriate cutting fluid when boring through steel to extend saw life. Always disconnect power or shut off the relevant service before drilling near live electrical or pressurized piping. Inspect the saw teeth for wear or damage before each use and replace if the cutting edge is compromised.
