EvolutionCC437L 7/16-Inch Diameter x 2-Inch Depth of Cut Cyclone High Speed Steel Annular Cutter

Had to cut some holes in a steel bench top for mounting some vises and hold-downs, and this thing could not have performed better. I used it in a Milwaukee mag drill and the holes were like they were cut with a laser. Didn't drill enough to evaluate its durability, but it got the job done for a fair price. Super happy with it.

Made very well drills holes and stays sharp

Drilled 150 13/16" holes in 1/2" thick A36 steel with a magnetic drill press, and still going strong!

Cuts cleanly with little wear to cutter

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.

great annular cutter did good job on 60 holes. on number 62 it barely finished drilling. 1/2' mild steel plate

Used this bit to drill a welding table. I have punched about 100 holes in 1/4 steel and the bit is cutting like new. I use proper cutting/cooling fluid and the bit stays cool cut after cut. Great cutter and good value for the money.

i bought 2 of these thinking that the process of drilling 315 holes on my fabrication table will consume both.. boy i was wrong, the bid cut like butter hole 1 until the very last hole 315.. very clean edge and the cutting edge remain sharp through out the whole process. the chip it makes it long like bird nest, just make sure to wear PPE when doing it and lube bottle on your Mag drill , it works very well for me to complete the job.

I bought this cutter to use with our new mag drill. Having little experience with annular cutters i bought this to see if they were more practical than traditional twist drill bits.This product arrived quickly and was put to work immediately. So far it has far exceeded my expectations for a ‘cheap’ annular cutter.We have drilled 400 holes in 1/2” mild steel and it still cuts almost as well as the first hole we cut. The price was active not all that great as I have since managed to source 5/8” annular cutters locally that are US made and are 5 dollars cheaper…. But in a pinch, or if there are no other available options, this cutter WILL do the work.

I have made about 40 holes in 3/16 mild steel and it is still cutting as if it were the first cut ie still very sharp. Very good value for the money. I use this with cutting fluid on a milling machine.

Have this cutter in several sizes and they’ve been doing good cutting clean holes and staying sharp.

Fit well , fast delivery, cuts like a champ

These are great cutters, crazy sharp, accurate and long lasting....well worth the asking price.
