My Counter Bit Set
Pictured is a set of the Milescraft counter bits that I use in my shop. I use the to drill pilot holes for screw sizes #6, #8, #10, and #12. I mainly use my to do this task. I have tried to use the hex bit in my drill but it always falls out as I am pulling out of the hole. I now take the bit holder out and use the counter sink right in the chuck. I do have another drill but it is kind of bulky. I like this set because it has the brad points and is relatively inexpensive.
