Starrett 65615 Hole Saw 7/8 in Carbide Tipped

Product Description

The STARRETT 65615 is a carbide-tipped hole saw designed for cutting clean, accurate holes through demanding materials. With a 7/8 inch saw diameter and a 1-5/8 inch cutting depth, it handles applications where standard bi-metal saws wear out prematurely. The toothed cutting edge and constant pitch pattern deliver consistent results across a range of substrate types. This hole saw is used by electricians, plumbers, HVAC technicians, and general contractors who need reliable penetration through non-metallic building materials without changing tools mid-job.

The 65615 is suited for residential and light commercial work where penetrations through fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring are common. Typical applications include running conduit or pipe through framed walls, cutting access holes in suspended ceiling components, and boring through fiber-reinforced panels. The compact 7/8 inch diameter makes it a common choice for low-voltage, plumbing, and HVAC rough-in work where smaller penetrations are required.

Key Features

• 7/8 inch saw diameter for precise small-diameter hole cutting
• 1-5/8 inch cutting depth handles typical wall and panel thicknesses
• Carbide-tipped construction extends tool life in abrasive materials
• Toothed edge with constant pitch pattern for smooth, consistent cuts
• Non-arbored design — pairs with a compatible arbor for your drill
• Rated for fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials

Compatibility

Designed for use in fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor applications. Requires a separately sourced compatible arbor for use with standard drill chucks.

Installation Notes

Installation is typically performed by electricians, plumbers, or HVAC technicians during rough-in. Always de-energize circuits and shut off relevant utilities before cutting near service lines. Secure the workpiece before drilling to prevent movement and ensure a clean cut. Use appropriate eye protection and dust control when cutting masonry, plaster, or fiberglass, as these materials generate fine particulate.
