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.

This Ojaiune 2" Hole Saw BI-Metal Heavy Duty Hole Cutter work great. I’m making an instrument panel for my Kayak. I purchased a water tight box to hold my instruments in. I had to drill holes for the instruments so that they would have only their screens out and the electronics protected from splashing and moisture. It worked great, now I have a compass and a battery gauge available for me to use while I’m fishing or just cruising on the lake. It also looks very professional.

This thing is super sharp and cuts a nice clean and accurate hole. I haven't used it a ton a ton but the dozen or so cuts I have made don't seem to have dulled the bit at all so it seems super durable. As safe as a sharp bit can be with the spring assist to get the cot piece out of the bit. A nice compact fit and great value for the money.

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

I purchased this over a year ago for installing recessed lighting and it's still cutting holes with ease.Great value for the money.I will definitely reorder when needed.

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.

Worked like a champ

Great product and seems pretty durable.
