Koopi 4.25 Hole Saw with Heavy Duty Arbor, 38mm Depth Bi-Metal 4 1/4 inch Hole Cutter for Easily Drilling Wood, Plastic, Plywood, Drywall, Thin Metal (108mm)

This little saw cut 8 holes through Hardy Soffit and I beleave it remains sharp enough to cut 8 more

This was an awesome investment. I used it for cutting holes in drywall to install Round outlet boxes for lights.

I was tall was as described I recommend using your drill and reverse when sawing sheetrock

I used this to drill one hole through steel siding, osb and some spray foam insulation in order to vent a bathroom basement exhaust fan. It worked perfect for my single hole. I ran it backwards at the beginning of the cut so it didn’t catch and I had a nice clean hole in the end.

Arrived safe and sound, used it to cut sheet steel. Easy cut through.

Its not crazy high quality, but if youre a DIYer putting in some wafer lights, it will do the job without falling apart. Pro tip: run it in reverse to keep your drywall cuts clean and dont push too hard.

Ordered this hole saw to install ceiling cans. It works great on the first three. After that It dulled quickly.

I HAD 50 LIGHTING ADAPTERS TO MAKE THAT I NEEDED TO MAKE A 6-3/8 HOLE IN 3/4 PLYWOOD TO INSTALL A WAFFER LIGHT IN , AND A SKILL SAW WAS GOING TO TAKE FOR EVER. SO I OREDRED THE HOLE SAW AND MADE A FIXTURE TO HOLD THESE IN A DRILL PRESS AND THE SAW DID THE TRICK SLICK AND EASY, QUALITY WAS GREAT COMPAIRED TO HIGH PRICED UNITS IT COMES WITH 2-DRILL BITS AND THE HOLDING ADAPTER AND HEX WRENCH, WOULD BUY AGAIN!!!

The hole saw diameter was perfect. The hole saw tool seemed of very good quality. But. But it will fit only 1/2 drills, not the more common 3/8 that I have (nor the smaller 1/4 size. My goof. The small print specifies this.

Fast shipping exactly what I needed
