James Carver –
Great tool. Eliminates multiple bits
Rafael Jones –
I’ve drilled through a whole bunch of different metal with varying thickness, and hardness and am pleased to report these have held up better than expected! They’re still sharp after a few months, and a bunch of projects.
Ronald Ogletree –
They came sharp and the plastic it cut spiraled out the top as expected and made quick work of the job
Jack Schmidt –
Worked perfect for getting through some aluminum. Used a little bit of lube and had no issues. Will definitely keep it
Brian Stadler –
So far excellent quality. Works better than a drill bit and you don’t have to de-burr your holes. Cuts real clean.
Zachary Solis –

Very satisfied with my purchase
William Basham –
It works great in car body sheet metal and that’s what i got it for
Brian Kratz –
So far I have used these to drill into a bunch of aluminum and a little bit of really thin steel. Worked well. The finish is starting to wear off but they still bore through fine. Again I would only look for great results with thin or softer metals.
Arturo Caplinger –
Anybody that uses step bits daily knows that these are the ones you use for heavy duty drilling, because they are good enough for the job.
