The 29-piece Black & Gold super premium set covers 1/16" through 1/2" by 64ths in a plastic Ultra Dex index case — every size in order, every bit accounted for, in a case built for the bench or the toolbox.

Toolbox and bench storage — the Ultra Dex plastic case keeps every bit in its labeled slot and travels well

About Black & Gold Jobber Bits

Black & Gold oxide is a super premium surface treatment that increases surface lubricity, reduces friction during cutting, and extends bit life compared to standard black oxide. It's the go-to finish for shops drilling steel regularly and running bits hard.

The 135° split point eliminates the need for a center punch on most materials — the bit self-centers on contact and begins cutting immediately. On the 3/16" and larger bits, three flats machined into the shank prevent the bit from rotating in a keyless chuck, which is the most common failure point when drilling under heavy load with hand-held equipment.

Jobber length is the standard working length for general drilling — long enough for most through-hole applications, short enough to stay rigid and accurate. This set covers every 64th-inch increment from 1/16" to 1/2", so you always have the exact size rather than forcing a close-enough substitute.
