Walter Surface Technologies01E618 29-Piece Jobber's Length Bits, Round Shank

Finally, I have found a quality set of bits. These babies are sharp, and stay that way a long time. I love good quality tools.

Excellent drill bits. I drilled through stainless with no problem. I did not have lube, but the bit did not burn.

I received these in a timely manner and arrived just as pictured in Amazon. These are meant to replace a set of cheapies and a set of irwin hss.The first thing i tried these on was broken leaf spring along side the others. the cheapies drilled into the leaf spring about 1/16 of an inch and the stopped. the irwins hss drill 3/32 into the spring and stopped drilling. and the walter pulled itself all the way through the spring. then i tried a couple other walter sizes and the same result. then we had a broken alternator bolt in a bracket housing that needed a 1 and 1/4 inch section of bolt drilled out for a easy out. again i tried the others and they failed. tried the walter bits and it was no problem. i used the same coolant on all the bits and drilled at a moderate speed. i will post more as i use them .Update: ok so I used this set in a small automotive shop for 1 1/2 years and every time i used them it was always with slow to moderate speed with cutting oil. I never spun the drill too fast, just enough that nice large shavings were produced. Most of the time they were used to drill out broken bolts and I never suffered a snapped bit which I was warned about with these. In that time I never had to sharpen the bits. When the owner ordered another set of bits I stopped using this set. I am very happy with this set.Please click helpful if this was of use to you.

Very good quality drill quick and last with every day use in steel

Great drill bits, they get the job done

I thought I was getting cobalt, and i am almost sure i got hss cobalt, they cut about the same as good as high speed steal, no where close to a good quality cobalt set, they dull very easy, they are equal to your average 39 dollar set. Probably my own fault for not doing the research before i made the purchase

Already had to replace some and the container tips over and bits fall out.

The best bits I have ever used and still remain sharp after constant use.
