I bought this for my home metal fab shop and a friend needed a bung welded into his exhaust and I’m also making a bumper with recovery points so I’ll need the 7/8 hole. I can see this lasting for dozens of cuts if not more so long as you apply oil.

Great bit for the money. I drilled 30 holes in 1/2” plate. Used a coolant/cutting fluid as would be normal for using this tool. Picture of bit is after drilling the holes. There in no discoloration at the tip and it’s still cutting just fine. Worth the money and lasts if used properly.

I drilled 84 holes with my 5/8 annular bit through 3/8” thick carbon steel. lt held up and kept sharp the whole process. I would definitely buy this again and again. Great price and great results. I will say to make sure when using a bit like this, to use a coolant of some kind.

I questioned these being worth the money, in that I can’t sharpen. I am double framing a truck. I purchased 3, 5/8 cutters. I’ve drilled more than 50 holes, in frame rail, I did have one shatter, 20+ holes in, but that could have been my fault for not being lined up. I’ve drilled 50 + holes, with two bits. 5/8 holes in mild steel is tough, I’m drilling truck frame. I bought 10 5/8 standard drill bits, hoping they’d be enough, with one man sharpening and one drilling? These are the deal, if you have the mag drill, buy them! I did keep them oiled/cooled, but that should be a given? Pleased!

Was hoping these would work drilling a truck frame. But these must have been over hardened or something because as soon as the bit started to cut it blew apart with a load bang. Put the other one in and it did the same thing. Ended up drilling it with a dull one we were using before. I'm sure this is just a messed up batch that made them this brittle. Just wish it wasn't my money wasted. I know it's a cheap brand but the other ones sold on here for almost half the price of these did fine.

I needed to drill 34 holes in 3/4" mild steel with this 7/8" bit. Unfortunately, I do not have a milling machine or mag drill, but only an underpowered drill press (1/2 max). Nevertheless, I got to 20 before it really bogged down. This could have been due to improper speed/feed rate/oil on my part which was impossible to perfect with my drill press. I drilled two more holes before realizing it's best to get another. I'm impressed regardless.The next bit I got was another brand (cheaper) and it bogged down after 10. Evolution is definitely worth a couple more bucks.

Really happy with this cutter so far. Goes right through 1/2 mild steel plate with ease. No chatter, breakage, or exsesive run-out. Makes clean perfectly sized 5/8 holes. Beats the heck out of a twist drill, hole saw or cheap ctc. Be sure to run at the proper speed, feed preasure, and lube/oil. I've been running this in an large variable speed industrial drill press with an accusize adapter without issue. If you are looking to run one of these in a drill press you will need a morse taper to 3/4 weldon shank adapter.
