Neiko Super-Hard 13 Pcs Cobalt Drill Bit Set These drill bits are the 13 piece sets in a compact folding index box. They are machined from hardened blanks that are alloyed with 18% Cobalt, giving them a durable core that will not easily snap and they'll hold their edge much longer and stay cooler. They will last ten times the life of standard high speed drill bits. They have 135° split points so they are self starting and won't walk all over your material. They will drill right where you put the bit, so there is no need for a punch or starter spot. The 13 piece bit set ranges from 1/16" to 1/4" by 64th's These bits all have round shanks
