Mk Morse mhsg40 Hole Saw 2.5 in Tungsten Carbide

Product Description

The MK MORSE mhsg40 is a tungsten carbide-tipped hole saw designed for cutting through hard and abrasive materials that would quickly wear out standard bi-metal blades. Part of the MHSG series, it features a steel body with a gulleted tungsten carbide cutting edge built to last through demanding applications in tile, masonry, cast iron, and composites. The saw has a 2.5-inch diameter and a 1-15/16-inch cutting depth, making it suitable for deep penetration work. It operates in the 70 to 205 RPM range and mounts via a 5/8-18 arbor with a 3/8-inch hex shank. A 1/4-inch diameter by 3-3/32-inch pilot drill is included. Electricians, plumbers, HVAC techs, and general contractors rely on this saw for jobs where standard tooling fails.

The mhsg40 is suited for both residential and commercial applications where cutting through hard or thin materials is required. The gulleted carbide edge clears debris efficiently and reduces the risk of chipping that can occur with standard carbide-tooth designs. Typical installation scenarios include cutting openings in ceramic tile, cement board, fiberglass panels, acoustic tile, computer flooring, and cast iron. The saw is also rated for use on asbestos board, brick, cinderblock, composites, Formica, hardened steel, and particleboard, giving it broad utility across multiple trades.

Compatibility

Designed for use with arbor MA35PSCT. Applicable materials include acoustic tile, asbestos board, brick, cast iron, cement board, ceramic, cinderblock, composites, computer flooring, fiberglass, Formica, hardened steel, and particleboard.

Installation Notes

This hole saw is installed by a licensed tradesperson or experienced technician using a standard 3/8-inch chuck drill rated for the 70 to 205 RPM operating range. Before beginning any cut, secure the workpiece firmly and ensure the pilot drill is properly seated in the arbor. Wear appropriate PPE including eye and respiratory protection, especially when cutting cement board, ceramic, or other dust-generating materials. Do not exceed the rated RPM range, as overspeed can damage the cutting edge and reduce tool life.
