Frequently Asked Questions
What exact sizes are included in this 13-piece set?
The set covers sizes from 1/16" to 1/4" in 1/64" steps: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", and 1/4".
What is the advantage of the black oxide finish?
The black oxide treatment increases abrasion resistance and helps retain cutting lubricants on the bit, which reduces friction and extends the working life of the high-speed steel during standard drilling operations.
