Great value
Size: 1/16-13pcs
These are perfect for predirilling and pilot holes. As small as they are none have broken so far. Worth every penny they cost.

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

Bad! Dull almost instantly. Buy something else.
Size: 1/8-13pcs
Bad! These are not good. Dull instantly or won't cut when new. I needed to drill a dozen holes in thin 18/20 gauge automotive steel and all 13 dulled or wouldnt cut from new before getting the job done. Theses are a joke. Dont wast your time.

Simple to use
Size: 30pcs-HEX
These are ok but break very easily. I personally would not buy these again i would rather spend more money and purchase better material. I have approx 6 bits that have broken with no abuse and little use.
