Starrett 65644 Hole Saw 5.5in Carbide Tipped

Product Description

The STARRETT 65644 is a carbide-tipped hole saw designed for cutting clean, accurate holes through a wide range of hard and abrasive materials. With a 5-1/2-inch saw diameter and a 1-5/8-inch cutting depth, this saw delivers the capacity needed for larger-diameter penetrations in demanding trade applications. The toothed cutting edge with a constant pitch pattern provides consistent material removal and reduces chatter. It is used by HVAC technicians, plumbers, electricians, and general contractors who need reliable performance when cutting through tough substrates on the job.

This hole saw is suited for residential and commercial construction and service work where oversized penetrations are required. Typical applications include running pipe or conduit through walls, floors, and ceilings constructed from fiberglass, Formica, masonry brick, MDF, plaster, or suspended flooring. The 5-1/2-inch diameter makes it a common choice for larger duct or pipe rough-ins. Note that this saw is non-arbored and requires a separately purchased arbor for installation in a drill driver or hole saw kit.

Key Features

• 5-1/2-inch saw diameter for large-bore penetrations in walls, floors, and ceilings
• 1-5/8-inch cutting depth accommodates typical framing and finish material thicknesses
• Carbide-tipped teeth maintain cutting edge longer than bi-metal in abrasive materials
• Constant pitch tooth pattern reduces vibration and produces a cleaner cut edge
• Non-arbored design allows pairing with a compatible arbor for standard drill chucks
• Rated for fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring

Compatibility

Designed for use on fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials. Requires a separately purchased arbor; confirm arbor compatibility with the 5-1/2-inch saw diameter before ordering.

Installation Notes

Install the hole saw onto a compatible arbor before use; confirm the arbor shank matches the chuck size of the drill or drill press being used. Secure the workpiece firmly before cutting to prevent material movement and reduce the risk of blade binding. When cutting masonry or abrasive materials, use appropriate eye and respiratory protection per OSHA guidelines. Allow the saw to cool between cuts to preserve carbide tip integrity.
