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

Bought for someone else

Bought this to cut a few holes for a cat tree I’m making. Worked flawlessly. Holes were cut into particle board. Very heavy duty. I was able to use this on my 20V Dewalt battery powered drill just fine.

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!

This item is dull and had difficulty cutting through sheetrock. One of the two locking pins broke while drilling the first hole.

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

I installed 24 spotlights in my basement and the first 5 I hand cut the ceiling. Then I got this product which really made my life east. Marking the spot and then boom, you got yourself a perfect hole. I wish the pilot bit was a bit longer so that placement would be a bit easier in high up places and your reaching.

I ordered this hole saw to drill a single hole to install a 6” vent pipe. For a single project, this is a great deal. The arbor was easy to connect and felt solid in the drill. Although it says compatible with glass, iron, and metal, I’m not sure I’d use it for any of them. Thin metal might work ok, but I can tell you the teeth are not as sharp or thick as my Milwaukee hole saw bits I normally use. Again, as this was a one-time use, I didn’t want to pay $35 for the name brand that would likely never be used again. I think it works fine for this, but if you plan to use it many times, especially with harder materials, you might be better served to buy a higher quality saw.

Tried drilling one hole with it on drywall and the bit broke off on the first one, I knew it was cheap but damn thought I could get at least 4 holes drilled.

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.

This is great but remember to have caution when using with a hand drill because it can catch and spin the drill and your arm with it.
