Starrett 65630 Hole Saw 2-3/4 in Carbide Tipped

Product Description

The STARRETT 65630 is a carbide-tipped hole saw designed for cutting clean, precise holes through a range of hard and abrasive materials. With a 2-3/4 inch saw diameter and a 1-5/8 inch cutting depth, this saw handles material thicknesses typical of wall assemblies, floor panels, and suspended ceiling systems. The toothed cutting edge runs on a constant pitch pattern, delivering consistent chip removal and reduced heat buildup during the cut. It is used by HVAC technicians, plumbers, electricians, and general contractors who need reliable performance when drilling through materials that dull standard bi-metal saws quickly.

This hole saw is suited for applications involving fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials. Its 2-3/4 inch diameter is a common size for running conduit, pipe, or duct penetrations through non-wood substrates. The carbide-tipped construction extends tool life significantly when compared to standard steel hole saws used on abrasive materials. Trades working in renovation or retrofit environments where mixed materials are encountered will find this a practical addition to the tool kit.

Key Features

• 2-3/4 inch saw diameter for standard pipe and conduit penetration sizes
• 1-5/8 inch cutting depth handles typical wall and floor panel thicknesses
• Carbide-tipped construction for extended life in abrasive materials
• Toothed cutting edge with constant pitch pattern for consistent chip clearance
• Rated for use in fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials
• Non-arbored design — requires a separate compatible arbor for use

Compatibility

Designed for use in fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor material applications. This saw is non-arbored and requires a separately sourced arbor sized to fit a 2-3/4 inch hole saw.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with hole saw operation and the relevant codes for penetrations through rated assemblies. Secure the workpiece before cutting and use appropriate eye and respiratory protection, particularly when cutting masonry or fiberglass. Confirm the correct arbor is mounted and fully seated before operation. Allow the saw to cool between cuts when working through dense or layered materials to prevent premature carbide wear.
