Starrett 65619 Hole Saw 1-3/8 in Carbide Tipped

Product Description

The STARRETT 65619 is a carbide-tipped hole saw designed for cutting clean, round openings through a range of tough materials. With a 1-3/8 inch saw diameter and a 1-5/8 inch cutting depth, this saw handles moderate-depth cuts in fiberglass, MDF, plaster, Formica, masonry brick, and suspended flooring. The toothed cutting edge and constant pitch pattern work together to maintain steady cutting action and reduce grabbing. It is used by HVAC technicians, plumbers, and electricians when routing pipe, conduit, or wire through finished and unfinished building materials.

This hole saw is suited for trade applications where a consistent, repeatable hole diameter is required across varied substrate types. At 1-3/8 inch diameter, it aligns with common 1-inch pipe penetration requirements in residential and light commercial construction. Its carbide-tipped construction extends service life in abrasive materials such as masonry brick and fiberglass insulation board where standard bi-metal saws wear quickly. It ships individually and is intended for single-use or low-volume trade work where a dedicated arbored saw is not required.

Key Features

• 1-3/8 inch saw diameter for 1-inch pipe size compatibility
• 1-5/8 inch cutting depth handles standard wall and floor thicknesses
• Carbide-tipped construction for extended life in abrasive materials
• Toothed cutting edge with constant pitch pattern for smooth, consistent cuts
• Non-arbored design for use with a compatible separate arbor
• Compatible with fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials

Compatibility

Rated for use in fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor applications. Compatible with 1-inch pipe size penetration requirements. Non-arbored — requires a separately sourced arbor for drill chuck mounting.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or electricians during rough-in or retrofit work. Always disconnect power and verify that no energized wiring, pressurized lines, or structural members are present behind the work surface before cutting. Use a compatible arbor with a pilot bit to keep the saw centered and prevent walking on hard surfaces. Eye protection and dust control measures are recommended when cutting masonry or fiberglass materials.
