I will never use hole saws again.
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.

Works as advertised
We used this to do our fixture table. Unfortunately I didn’t think far enough in advance to get the 2” cut depth. It works as intended & holds tolerance.

Worked awesome
This bit worked fantastic. Had no problem cutting out the 14 holes in 3/4" steel plate.

No 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.

Good low cost annular bits
Using these at a fabricating company that I own. No issues so far. Works great and lasts with proper coolant application. We double check dimensions prior to cutting with them. Sizing is spot on.

Very sharp, good quality
Chucked it in a 3/4" standard collet and it spun with no runout. Machines fishmouths in 1"x.035" tubing perfectly. Also used to machine lightening holes in a case hardened sprocket, and it worked great. No loss in cut quality after 20 holes
