Starrett 65618 Hole Saw 1-1/4 in Carbide Tipped

Product Description

The STARRETT 65618 is a carbide-tipped hole saw designed for cutting clean, accurate holes in a range of hard and abrasive materials. With a 1-1/4 inch saw diameter and a 1-5/8 inch cutting depth, this saw handles applications where standard bi-metal saws wear prematurely. The toothed cutting edge and constant pitch pattern deliver consistent results across varied material densities. It ships as a single, non-arbored unit, so a compatible arbor must be sourced separately. Tradespeople and installers working with fiberglass, masonry, or dense panel materials will find this saw well-suited to production and service work alike.

The 65618 is intended for use in fiberglass panels, Formica laminate, masonry brick, MDF, plaster, and suspended floor assemblies. It is a strong choice for HVAC installers cutting access openings in composite or masonry surfaces, plumbers routing through framed walls with mixed materials, and general contractors handling finish or retrofit work where material hardness rules out standard steel-tooth saws. The 1-1/4 inch diameter is commonly used for conduit knockouts, pipe penetrations, and similar small-diameter through-holes in rigid substrates.

Key Features

• 1-1/4 inch saw diameter for small-diameter penetrations in rigid materials
• 1-5/8 inch cutting depth accommodates standard framing and panel thicknesses
• Carbide-tipped construction resists wear on abrasive surfaces like masonry and fiberglass
• Toothed cutting edge with constant pitch pattern for consistent, predictable cuts
• Non-arbored design — pairs with a separately sourced arbor for use in standard drill chucks
• Rated for fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials

Compatibility

Designed for use with fiberglass, Formica laminate, masonry brick, MDF, plaster, and suspended floor assemblies. Requires a separately sourced arbor; not compatible with direct-mount drill chucks without one.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary cutting tools and the substrate being penetrated. Secure the workpiece fully before cutting and ensure the drill or driver is set to an appropriate speed for carbide-tipped saws in hard materials — consult the drill and saw manufacturer guidelines for recommended RPM by material. Because this saw is non-arbored, confirm arbor compatibility before use. Always wear eye protection and dust control measures when cutting masonry, fiberglass, or MDF, as these materials generate fine particulate.
