Milwaukee Hole saw HOLE DOZER 21

Milwaukee Bi-Metal Hole Saw, Hole Dozer, 21 mm

Cutting-edge technology for unparalleled durability. Tooth geometry: variable 4 - 6 TPI Vario-tooth design with a positive 10° tooth angle for faster and more aggressive cuts, reduced heat generation for longer tooth life, and deeper tooth depths for better material removal. Specially shaped teeth reduce binding in thin materials. The staggered tooth spacing reduces friction. Due to the aggressive tooth design and effective material removal, less pressure is required.

Tooth material: high-quality HSS alloy with 8% cobalt content for optimal durability even in metal. Bi-metal construction with electron-welded HSS teeth on a special steel body for optimal cutting quality and long lifespan. The high wear resistance of the premium HSS alloy makes these hole saws ideal for demanding tasks, such as cutting stainless steel, acid-resistant metals, and softer materials like wood.

Hole saw body: 1.27 mm thick steel body is very stable yet self-elastic. Effective cutting depth of 41 mm. Heavy-duty back: strong steel back ensures high stability and reduced vibrations. 4 pin holes for easy locking of the adapter. Precisely manufactured, perfectly round back for optimal run-out, especially important for hole saws of larger diameters. Unique cutouts facilitate the removal of the drill core.

Applications: state-of-the-art production processes ensure precise run-out, allowing the hole saws to be used in both handheld tools and stationary devices. This high-quality range of hole saws is the perfect solution for cutting steel up to 1000 N/mm tensile strength, stainless steel and acid-resistant steel, non-ferrous metals, cast iron, aluminum, wood, MDF boards, drywall, sandwich materials, and plastic.
