29件 M7 1/16英吋至1/2英吋替換鑽頭，僅鑽頭，無收納盒

Snapped a 3/16 bit on a hinge job and these replacements fit right in my old index. The full range from 1/16 up to 1/2 covers basically everything I drill, and they bite clean through oak without wandering.

I already had a case from an old set, so paying less for just the bits was perfect. Every size from 1/16" to 1/2" is in here, and they cut through metal cleanly without wandering.

The 29-piece range from 1/16" up to 1/2" covers every size I actually reach for, so no more digging through mismatched singles. The bits bite cleanly through mild steel and the flutes clear chips well. Buying the refill only was perfect since I already had a case.
