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

I had to cut a bunch of 6.1 inch holes into drop ceiling panels for canless LED lights. I tried to use a utility knife first... That was awful! This blade cut it nice and smooth. You need a bigger drill... It is large and you need to get the speed up before you dig in. Saved me a ton of time and frustration! Worth much more than the cost.

Not much to say it made a hole so success!?

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

Has done its job thru plywood for recessed lights, no issues cant say that about the light unfortunately. Would recommend

Bought this hole saw because I thought it would be the better option. Came with 3 bits. One bit was broken in the box upon receiving it. Not a big deal, there was 2 more. Attempted to use it on some sheet metal, wouldnt cut through it. The Allen screw to secure the drill but doesnt stay tight, just vibrates loose and falls out no matter how tight you make it. Also the locking mechanism fell apart so its no longer usable. I ended up getting done what I needed, it at least made a nice template in the sheet metal and I cut the rest out with a dremel.

The second time we used this, it busted off the base. Completely useless after that.

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!

Turns out my wife wanted me to make some corn hole boards. 6 to be exact. I know a jigsaw was not the answer. This was. Easy to use. Made a nice 6 circle and that is what I needed. Good buy.

This comes with everything you need right in the box. Sometimes you have to spend more money on an arbor or center mount. This has all of that so you can just open, assemble, and get to work in a few minutes. It is a beast on the cut teeth. I purchased to use to install a 6 inch ducting system for a laser cutter exhaust. It cuts 152 mil which is 2 mil larger than the ducting I am using. Duct hose and fittings all fit perfectly with this size. You will get years of service from this.

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