Use the Milwaukee 4 in. Bi-Metal Hole Saw to cut holes in a variety of materials. The steel hole saw can drill almost 2 in. D. Milwaukee Ice Hardened products utilize a proprietary cryogenic hardening process that improves upon traditional heat treat processes. Unlike surface coatings that wear away, cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (Marten site). The result is a product that is more consistently hard throughout, resulting in life up to 50% longer than the competition.

Can I use this hole saw in drill press to cut thru Clear Extruded Acrylic Plexiglass Sheet 3/8 inch thick?
If yes, then what speed is recommended, 600 RPM or lower? Should I use any fluids to reduce generated heat? Thanks, Max

Answer: 
Yes, the Hole Dozer can cut through thick steel, even I-beams. For thick steel low RPM with generous cutting fluid/wax is recommended.

Hi Geo, here is a list of the Milwaukee quick arbors that work with this hole saw.
Just make sure you match up the arbor that works with your drill chuck size.
For fast, tool-free change-outs, use Milwaukee's universal Quick-Change Arbors. 49-56-7210, 49-56-7240, 49-56-7250 and 49-56-9100.
