Cobalt Jobber-Length Drill Bits
Available59 products
Cobalt jobber-length drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel drill bits. They provide some shock absorption and can be used in handheld power tools. Jobber-length drill bits are the most commonly used drill-bit length. They provide a good balance of strength and accuracy when drilling into a variety of materials.

TiCN-Coated Parabolic-Flute Cobalt Jobber-Length Drill Bits
The TiCN coating on these drill bits protects them from wear and is harder and more wear-resistant than a TiN coating. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drills move deeper into the workpiece.
