Milwaukee Bi-Metal Hole Saw for Stainless Steel, Metal, Wood, Acid Resistant Steels

This hole saw is a seven-piece bi-metal set supplied in a plastic case for workshop and site use. It includes multiple cutting diameters and an arbor, enabling controlled circular drilling across a range of materials with an effective sawing depth suitable for through-panel and thicker workpieces.

• Matrix II HSS teeth retain hardness at high temperatures
• Laser-welded teeth on alloy body extend tool life
• 1.27mm body thickness keeps shape while allowing flexibility
• 3.5 TPI tooth form for faster, aggressive cutting
• Diagonal slots simplify core ejection and removal
• 41mm effective cut depth for deeper hole requirements

• Suitable for cutting holes in stainless steel panels and flanges
• Used for fabrication tasks on acid-resistant steels
• Ideal for electrical conduit and cable entry installations
• Suitable for mechanical enclosures and metal chassis work
• Used for timber penetrations in mixed-material assemblies

The kit contains five holesaw diameters of 19mm, 22mm, 25mm, 29mm and 32mm Plus an arbor and associated spacer and adaptor.

The toothed edge uses a cobalt-enriched high-speed steel that maintains hardness at elevated temperatures, improving wear resistance when cutting hard alloys.

An arbor is supplied that fits holesaws from 14mm to 30mm, with an included 1/8″ Allen key for assembly and an adaptor for compatibility.

The body features diagonal slots which promote efficient chip clearance and reduce clogging during prolonged cuts.
