Starrett 65623 Hole Saw 1-7/8 in Carbide Tipped

Product Description

The STARRETT 65623 is a carbide-tipped hole saw designed for cutting clean, accurate holes in hard and abrasive materials. With a 1-7/8 inch saw diameter and a 1-5/8 inch cutting depth, this tool handles demanding applications where standard bi-metal saws wear out quickly. The toothed cutting edge with a constant pitch pattern delivers consistent material removal and reduces chipping. It is a non-arbored saw, so a compatible arbor must be used for installation in a drill or drill press. Plumbers, electricians, HVAC techs, and general contractors reach for carbide-tipped saws when cutting materials that destroy lesser blades.

This hole saw is suited for use in residential and commercial applications where penetrations must be made through fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring materials. Electricians cutting through plaster walls, HVAC installers penetrating fiberglass duct board, and plumbers routing through MDF or composite panels will find this saw appropriate for those tasks. It is sold as a single unit without an arbor included.

Key Features

• 1-7/8 inch saw diameter for standard-size penetrations
• 1-5/8 inch cutting depth handles typical wall and panel thicknesses
• Carbide-tipped construction extends service life in abrasive materials
• Toothed cutting edge with constant pitch pattern for smooth, consistent cuts

Compatibility

Designed for use in fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials. Requires a separately purchased arbor compatible with standard hole saw shanks.

Installation Notes

Installation of this hole saw requires a compatible arbor — verify arbor thread size before use. Always secure the workpiece and use appropriate eye and respiratory protection when cutting masonry, fiberglass, or composite materials that generate fine dust. Disconnect power to the drill or drill press before changing or mounting the saw. Follow applicable workplace safety codes when cutting into building assemblies.
