Jonathan R. –
Good quality sharp drill bits made in the USA. They did the job really well.
David S. –
Good quality drill bits, handy for removal of a snapped bolt in a car engine, being a left handed thread. Cobalt can be brittle, but with care it did the job nicely for me and I used a drilling and cutting oil.

Good quality

Correct use in slow speed reverse and the 5/32 bit died on first day of use. Took the remnants out of the chuck to inspect and “made in Brazil” have I just paid over the odds for a knock off?

These work very well for drilling out manifold bolts. The bits are a “jobber” length. From factory the cutting faces on these bits are consistent at 135°. The bits are all straight and cut straight as well.

You get what you pay for
Used 4 sizes, including the smallest and the largest and so far, they are cutting through thick metal like butter. I remember such drill bits when I was young, before the markets got saturated with cheap bits that don’t last or don’t even do the job. These are remarkably well made and are worth the money. Just remember to use oil to cool them while drilling.
