Hole Saw for Metal MILWAUKEE 44 mm Bi-metal (A113MO10044)

Bi-metal hole saw from MILWAUKEE with a 44 mm cutting diameter designed for producing clean circular holes in a variety of metallic materials. The cutting tool is intended for use with drills or compatible hole saw arbors and is manufactured from bi-metal to balance cutting performance and durability. It is suitable for tasks that require accurate 44 mm openings in sheet metal, pipes and structural profiles, and can be used by professionals and DIY enthusiasts engaged in metalworking projects.

Advantages

The bi-metal construction combines high-speed steel cutting edges with a flexible alloy body, offering increased wear resistance and reduced breakage risk compared to single-material saws. The 44 mm diameter provides a standard, precise hole size for fittings and penetrations, while the tooth geometry is optimized for efficient metal cutting and reduced burr formation. Designed for secure mounting on standard arbors, the saw enables stable cutting and consistent results across repeated use.

Suitable for

• Cutting circular holes in sheet metal and metal panels
• Creating openings in metal pipes and tubing
• Drilling holes for fasteners, grommets, and cable glands in metal enclosures
• General metal fabrication and repair work requiring a 44 mm hole

Key specifications

• Cutting diameter: 44 mm
• Material: bi-metal construction (HSS cutting edge with alloy body)
• Intended use: metal cutting (sheet metal, pipes, structural profiles)
• Mounting: compatible with standard drill arbors and hole saw adaptors
• Design focus: wear resistance and durability for repetitive cutting

How to use

Securely attach the hole saw to a compatible arbor or drill adapter, ensuring the pilot bit (if present) is properly fitted and centered. Mark the center of the intended hole on the workpiece and clamp the material to prevent movement. Use a drill or drill press at an appropriate speed for the metal being cut, applying steady pressure without forcing the saw. Periodically withdraw the saw to clear metal chips and reduce heat buildup. After cutting, deburr the edge of the hole as needed to achieve a clean finish.

Usage recommendations

For optimal lifespan and cutting performance, use cutting lubricant when working with thicker or harder metals, maintain moderate drilling speeds suitable for the material, and avoid excessive side loading. Replace the saw if visible wear or tooth damage occurs to preserve hole quality and operator safety.
