Evolution CC625 5/8-Inch Diameter x 1-Inch Depth of Cut Cyclone High Speed Steel Annular Cutter

Having finally bit the bullet and procuring a mag-drill recently, I've been slowly buying annular cutters as the need arises. First few I bought were Jancy Sluggers, but I decided to give these a try as they are also highly rated and somewhat less expensive. I like that these come with the pins without having to dig through the listings, having the buy those separately is a pain (and typically pricey). I used the cutter I purchased to gang drill 1/2 plate (4x plates, so 2" at a time, and yes I got a 2" depth cutter). Cutter performed very well, no chips or even discoloration on any teeth even after drilling a total of 16" of steel. I did use cutting oil (and yes it's required if you're not familiar with machine tooling), nothing too specific, just the general purpose cutting oil I had on hand. Note: If you gang drill as I did, you will have to remove the slugs from each layer as you go, the last bit of the cut always stays on the slug and that will not cut when it's spinning in the hole, this is not a fault of the cutter, there's really no way to prevent this with annular cutters. I am quite pleased with these cutters and will be looking at more of these as I run into a need for them.

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.

Good quality bit it served it's purpose and still usable

Worked well on 1/4" aluminum. Stayed sharp.

I bought this 5/8" Annular drill bit because, 1- it's an Evolution bit and 2- because of the high ratings it received, However, after drilling only 25 holes in 1/2" steel sheet for my welding table build the bit shattered. The mag drill I used has a water cooling port with constant flow through the center of the drill bit and keeps the bit fairly cool and lubricated during the drilling process. Not sure if it failed because it was defective or because of other reasons, but either way I was very disappointed, especially given the price I paid for the bit.

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!

Drilled about 400 holes in a piece or 1/2 steel for a welding table…I was using a magnetic drill press but the bit worked flawlessly and I think it’s good for quite a few more.

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.

Used to drill holes in a double frame truck" works awesome

Cuts holes, lasts decent.

Buen cortador, hasta el momento sin problemas, para taladros magnéticos..

Did the job, we drilled a lot of holes with it!!

Great product! Worked perfectly.
