6 inch/152mm Hole Saw Heavy Duty Bi-Metal HSS Hole Saw for Cornhole Boards, Plywood, Iron Board, Acrylic, Ducts, Ceiling Lights, Cinder Wall

Pretty heavy duty, worked great!

Its trash, Complete garbage, did not cut one metal hole. After trying to cut metal the teeth were complete ruined...

One part of the description says this hole saw is for soft metal. Another part of the description says it is for thin metal. The description also states the Compatible Material as being Engineered Wood, High Speed Steel, Wood, Glass, Plastic, Iron, Metal. **I wonder how this hole saw is supposed to cut through glass??? LOL! Then the description contradicts the previous statements by stating Applications: drywall, plywood, acrylic, wood, plastic, thin metal, etc. (Note: not used in ceramics, glass, thick iron, cement and other hard materials). ** So now it cant cut through glass, or any other hard materials. AWESOME! ;-) The first one of these hole saws I purchased cut through several pieces of 1/8 plywood without difficulty, but was completely dull after cutting through 2 pieces of common sheet metal, such as that used for standard HVAC duct work. Notice the flattened teeth in the attached picture. Nevertheless (and against my better judgement,) I ordered another one to cut through more 1/8 plywood to finish the job, but it didnt have the center bit holder. Save yourself some frustration, and dont waste your money or time on this WORTHLESS JUNK. Buy a well known name-brand. At least you will probably get all the pieces and parts. NOT RECOMMENDED WHATSOEVER!

I am setting up cornhole boards using Baltic Birch. I had to switch to a corded drill as i couldnt get very far in a cordless. Overall I think it would work better with something like a drill press, but just wasnt as easy to get thru multiple board surfaces to make the 6 hole. Even though it was a fair price, i decided to return it. Teeth for me werent as sharp as i felt they could have been.

It made making our cornhole boards a breeze

Used these on a remodel to cut in a couple can lights through plaster walls. This worked great. Only used for two holes but cut like butter.

Cutting large holes can be a challenge. This saw worked great.

Seems well built. Biggest issue is I did not receive the allen screw that is clearly shown in the pictures. Not a huge deal I can just go out and buy one - buts its annoying that I have to. Review Update. First time using it (in drywall - nothing tough) the drill bit snapped on the 5th hole. My opinion now is its garbage

This hole saw cut 16 (sixteen) 6 holes through 3/4 Shop Birch plywood and still in good shape. Each hole was somewhat slow going, about 10-15 minutes per hole with pauses to keep from overheating and to brush teeth. Cutting from both sides assured clean cuts on both sides and did router to smooth edges, but no chipping or gouging. Super happy with results.
