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.

• This High-speed steel (HSS) Jobber Drill bit provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials. Their Spiral flutes are constructed with a higher flute angle to remove chips more easily. Oxide also known as black oxide or steam oxide is a surface treatment that prevents chip building galling and welding on the workpiece. It is commonly used on low carbon stainless steel and ferrous metals. Spiral flutes are constructed with a higher flute angle to remove chips more easily.
