About This Product

This MOLLOM hole saw is a serious piece of cutting gear for bigger jobs.

It's 222mm (8-3/4 inches) in diameter, with a cutting depth of 38mm (1-1/2 inches)—plenty for cutting through thick materials like plywood, drywall, plastic, gypsum board, rubber, and even thin sheet metal.

The teeth are made from M42 high-speed steel with 8% cobalt content, which gives it a hardness of 67-70 HRC.
That means it stays sharp longer and handles heat better than basic hole saws.

It comes with two titanium-plated pilot drill bits and a hex shank arbor that fits 11mm (7/16 inch) chucks or larger.
The arbor has a spring ejector that pops out the cut disc automatically, so you don't have to pry it out.

Variable tooth pitch reduces vibration and gives you a smoother cut.

Works great for DIY projects like recessed lights, air ducts, cornhole boards, or speaker installs.

Just go slow with metal and use cutting oil.

Solid build, good value.
