Starrett 65626 Hole Saw 2-1/4 in Carbide Tipped

Product Description

The STARRETT 65626 is a carbide-tipped hole saw designed for cutting through demanding materials including fiberglass, masonry brick, Formica, MDF, plaster, and suspended flooring. It features a 2-1/4 inch saw diameter with a 1-5/8 inch cutting depth and a constant-pitch toothed cutting edge that delivers consistent bite through dense or abrasive substrates. This saw is sold individually and is not arbored, meaning it requires a separate compatible arbor for operation. It is the right tool for HVAC techs, plumbers, and electricians cutting access holes through walls, ceilings, and composite panels during rough-in or service work.

The 65626 is suited for trade applications where standard bi-metal hole saws wear prematurely against abrasive materials. Carbide tipping extends tool life significantly when cutting through fiberglass duct board, masonry brick, plaster lath, MDF panels, Formica surfaces, and suspended flooring assemblies. It is appropriate for both new construction and retrofit work where clean, accurate holes are required through mixed or layered materials. The 2-1/4 inch diameter corresponds to a 2-inch pipe tap compatibility, making it a practical choice for piping and conduit rough-in applications.

Key Features

• Carbide-tipped cutting edge for extended life in abrasive and hard materials
• 2-1/4 inch saw diameter with 2-inch pipe tap compatibility
• 1-5/8 inch cutting depth handles typical wall and panel thicknesses
• Constant-pitch toothed edge provides consistent cutting action
• Not arbored — requires a separate arbor, allowing use with existing arbor sets
• Rated for fiberglass, masonry brick, Formica, MDF, plaster, and suspended floor materials

Compatibility

The 65626 is compatible with material applications including fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor assemblies. It is not arbored and must be paired with a separately sourced arbor. A 2-inch pipe tap compatibility is specified for piping and conduit layout work.

Installation Notes

A licensed electrician, plumber, or HVAC technician should confirm correct hole sizing before cutting, as carbide-tipped hole saws do not allow for field adjustment of diameter. Ensure the workpiece is secured before beginning the cut. Because this saw is not arbored, verify arbor compatibility and proper engagement before operation. Always wear appropriate eye and respiratory protection when cutting masonry, plaster, or fiberglass.
