Jobber Length Drill Bit, Drill Bit Size 3/16 in, Drill Bit Point Angle 135 °, Cobalt
- Item # 1G873
- Mfr. Model # 46612
- UNSPSC # 23171609
- Catalog Page # 2243 2243
These drill bits meet National Aerospace Specification (NAS) 907 Type J for drill bits used in aircraft repair and production. They have a have a straw/bronze finish that improves their wear resistance, and they have spiral flutes that evacuate chips as the bits drill into a workpiece.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.
