Large Small Index Overall Size. Has the four most used bits in my work. Good coverage, excellent tip geometry. In combination with the right speed and feed, they cut very well. In the photo these drill bits are drilling through hardened 1095 steel on a knife and architectural steel rod for a scribe.

Very good drills. Get the job done with no complaints on most projects. Plain and harder steel was not a problem. However, they are far inferior to the hardest and strongest hardened steel.
