quality item
they are well made and come in a nice box...3 flats on the shank insure positive grip in the chuck...that extra bit of manufacture tells you they are superior in build.

I use gear oil as a cutting fluid. Works great, bits last a long time, Amazon has it too
I've been working with metal for the better part of 50 years. This NEIKO Bit Set is great I used them so I could use counter sink screws in 3/16" metal (NOT aluminum) Metal Diamond plate. Mighty sharp Like a hot knife through butter. I'm very happy with this purchase. We were putting this metal diamond plate down on the bed of a box truck. About 75 holes before we weld it in. 5 bits come in a little case. It took 2 days to get.......... Thanks for hooking me up Amazon.
