complete junk
Would Not RecommendI had an aluminum tool box which I was adding onto my alloy steel headache rack. The small 9/64 bit for the pilot hole ripped thru the aluminum breezed thru the alloy steel and right thru the side rail of the bed, perfect. Put the new 1/2 in bit in right thru the aluminum hit the alloy steel and nothing a complete dead stop mind you this was the very first hole was using a cutting oil and wasnt over heating the bit but she just flat out refused to go thru the steel. So after much cussing I went ...
Quality materials.
Would RecommendExactly like the description.

Long, brittle bits. Use only in drill press.
Would Not RecommendThey broke very easily when used in a hand drill. Might work okay in a drill press. They cost little and still provided decent value.
