Product Specification

#28 HSS BLACK OXIDE JOBBER LENGTH DRILL BITS - 12 PACK

#28 HSS Black Oxide Jobber Length Drill Bits - 12 Pack is a drill bit that has a long length compared to its diameter. These bits provide more flexibility and absorb more shock and vibration than cobalt, powdered-metal, and carbide jobber-length. These jobber bits have a good balance of strength and precision when drilling into a range of materials. Each jobber bit is commonly used in softer materials such as wood, soft metals, or composite. They come in a wide range of sizes, finishes, and materials. Our jobber bits are designed, engineered, and superbly crafted to provide long-lasting durability.

A 135 degree split point designed to prevent wobbling, walking or skating and eliminate the need for a pilot punch. These bits are manufactured from M2 high speed steel and heat treated to ensure an extended life and optimal performance cutting holes. The black oxide finish provides increased abrasion and corrosion resistance.
