Cheap, low quality bit. We barely got through one cut and couldn't pull out the slug. Without applying much pressure and also backing off the cut, the bit heated up rather quickly. Used lots of cutting oil but still didn't help.
We cut through 1" thick steel plate. Im not sure thinner material would make it better as we weren't even half way through when this thing quick cutting.

I will never use hole saws again.2016年12月21日 - 已在美国亚马逊上发表
I will never use hole saws again. Oh man, in a good drill press or mag drill these things are a life saver. Hole saws dont last but these do. I drilled 8 holes in half inch plate steel with this and it took it like a champ and can still cut more. Dont forget to use some cutting oil to prolong the life also dont forget the pilot pin.

Item not as described. No pin. We couldn't use it and held up the job. If people want to sell industrial supplies on Amazon. they should realize how a little that we depend on accurately described products. MSC might be expensive but they get it right.

Drilling holes in 7/8" thick ibeam and this thing was much faster and took less force to pass through the beam than the other cutters I own by jancy and others. In short it does the job well.
