6 1/4 inch Hole Saw, Bi-Metal & Heavy Duty Hole Saw with Arbor Mandrel, Hole Drilling Cutter for Cornhole Boards, Metal, Drywall, Plasterboard, Wood and Plywood

I ordered this because it had the size I needed; 2 1/2 diameter. Well, it is actually more like 2 1/4 so the hole I drilled is too small. I measured the hole saw labeled 2-1/2 64mm and it is 2-1/4. Such a disappointment!

Used once to cut through sheet metal. Worked fine.

Definitely worth the purchase

Drill bit fit perfect, worked perfect, absolutely the exact thing that we needed to drill a hole to install an exhaust vent/fan

I got the bi-metal set and so far they works absolutely perfectly

Great value for this hole saw. Ideal for drywall and soft materials.

I cut 3 6 inch holes in painted 1/2 half inch drywall. The hole saw is worn out and will not cut anymore. No bueno.

Dont expect this to last you a long time. We have used one blade and it was beginning to dull before we even cut through the side of a cabinet (particle board, not even hardwood).... So, I expect well get about one use out of each size we have to use. Didnt expect it to be disposable but thats about what it is. I worried when I got it because the shank was huge .... but the chuck on my husbands Craftsman did manage to open enough to hold it - definitely a 1/2 shank on the mandrels.

Plenty of hole saws for every size

Used it to cut holes for 6 vent pipe. This thing is heavy and very sturdy. For the price its a bargain. Im not sure how long it will stay sharp, but it it will do the job without complaint.
