Industrial M011120 Annular Cutter

Description:

The M011120 Annular Cutter is used in magnetic drilling systems and metal fabrication equipment to produce fast, accurate, and burr-free holes in structural steel and heavy plate materials. Commonly installed in portable magnetic drills, fabrication shops, structural steel facilities, and industrial maintenance operations requiring precision hole cutting. Maintenance technicians, steel fabricators, and machine operators use this cutter for equipment fabrication, field installation work, and replacement of worn cutting tools. The alternate number 12228 corresponds to the industry-standard 7/8 in x 2 in annular cutter size.

Applications:

The M011120 annular cutter is commonly used in structural steel fabrication, bridge construction, shipbuilding, industrial maintenance, and manufacturing facilities where large diameter holes must be drilled quickly and efficiently. Annular cutters remove only the material around the circumference of the hole rather than converting the entire hole into chips, resulting in faster cutting speeds, reduced horsepower requirements, and improved tool life compared to conventional twist drills. These cutters are frequently used with portable magnetic drills and stationary drilling equipment for beam, plate, pipe, and channel fabrication.
