M.k. Morse 177337 Bi-metal Hole Saw 2-1/16 Inches

Product Description

The M.K. MORSE 177337 is a bi-metal hole saw with a 2-1/16 inch cutting diameter, built for demanding trade and construction applications. Manufactured from M42 high-speed steel with a variable-pitch, toothed cutting edge, it delivers controlled, efficient cuts through a wide range of hard and composite materials. The cutting depth reaches 1.937 inches, making it suitable for through-cuts in standard framing, tile, cast iron pipe, and layered composite panels. This saw is compatible with the MHS33 arbor and is the type of tool stocked by electricians, plumbers, HVAC techs, and general contractors who need consistent, repeatable hole geometry on the job.

This hole saw is suited to both residential and light commercial work. It handles applications across multiple material categories including steel, hardened steel, cast iron, ceramic, fiberglass, cement board, cinderblock, brick, acoustic tile, asbestos board, composite, computer flooring, Formica, and particleboard. Whether cutting knockouts in electrical enclosures, core holes in masonry substrate, or penetrations through flooring panels, the 177337 provides a single tool solution across diverse materials commonly encountered in trade work.

Key Features

• 2-1/16 inch saw diameter for standard knockout and penetration sizing
• M42 bi-metal construction for durability in ferrous and abrasive materials
• Variable-pitch tooth pattern at 5/6 TPI reduces vibration and chatter during cuts
• 1.937 inch cutting depth handles most single-pass through-cut applications
• Toothed edge design maintains cut geometry across both hard and soft materials
• Compatible with MHS33 arbor for quick setup and blade changes

Compatibility

Designed for use with the MHS33 arbor. Compatible with standard drill presses and handheld drills accepting the appropriate mandrel. Suitable for cutting acoustic tile, asbestos board, brick, cast iron, cement board, ceramic, cinderblock, composite, computer flooring, fiberglass, Formica, hardened steel, particleboard, and steel.

Installation Notes

Hole saws of this type are installed by electricians, plumbers, HVAC technicians, and general contractors using a compatible arbor and a corded or cordless drill or drill press. Ensure the arbor is fully seated and the locking mechanism is secured before operation. Keep cutting speed appropriate to the material being cut to avoid overheating the saw body. Eye protection and appropriate dust or particulate controls should be used, especially when cutting cement board, ceramic, or any material designated as a hazardous substrate.
