    • Cheap replacement for all the small drills you break
Like most of us, it's always the small drills that break the easiest. One little goof with the drill press and plink, there's a couple of bucks you'll never get back. What I like about this drill bit set is that they include a large number of duplicate small bits. I replaced the missing ones earlier broken in my drill index and I imagine I'll get a few years of a full index before I have to buy another set. I went into this purchase fully knowing that considering the country of origin (China) the quality would be suspect. But they appear adequate - I was drilling some steel yesterday and no problems. Best advice: use a drill press if you can, always use a drop of cutting oil on the bit as you drill into metal, use a relatively slow speed, and be sure what you're drilling is firmly fixed in place; the smallest movement will snap the drill. For wood or plastic these work fine, for metal just be gentle. ... show more
