51mm/2" Hole Saw BI-Metal Heavy Duty Hole Cutter for Wood Cornhole Boards Plastic Drywall Fiberboard

Worked perfectly for mounting JL Audio 7.7” marine speakers, cut through my gel coat with out chipping! Great Purchase.

I needed this to cut door handle holes in two ABS panels for my 1985 VW Vanagon, and it worked like a charm. Now that I see what this is capable of, I'll no doubt find more uses for it around the house, such as drainage holes in plastic flower pots.

As expected, this hole saw is heavy duty, great quality, and SHARP. It got the job done: cutting through hardwood flooring. True to size, and definitely burn resistant.

Convenient and efficient, arrived on time to do some work.

Great product and seems pretty durable.

This product works just fine, but there is a safety issue. The arbor that comes with this hole saw does NOT have pins to couple it to the blade. That means if you stop the drill while it is going at high speed, the momentum of the hole saw will keep it spinning as the arbor stops. The hole saw unthreads itself from the arbor and keeps spinning. The fix to this is an arbor with pins that doesn't allow the hole saw to keep spinning when the drill turns off.No complaints about how it actually cuts, it does that just fine.

After a few seconds of going nowhere with a 1-1-1/2” spade blade in old 3/4” plywood in a hot attic, I ordered this hole saw. It ripped through to the other side in no time! Very sharp and the extra drills are a plus. I’ll remember this brand for future project.

Worked like a champ
