Product Specification

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

#44 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.

      Sebastian ★★★★★

      Finally, a set of #44 bits that doesn't wander on the first plunge into brass. The black oxide coating seems to grip the chuck better and the jobber length gives me just enough reach without flexing. Twelve in the pack means I actually have a spare when I inevitably snap one.

      Thomas ★★★★★

      Grabbed these for jewelry work and the black oxide finish really helps them bite into stainless steel without wandering. The #44 size is perfect for my pin vise, and the pack gives me plenty of spares.

      Riley ★★★★★

      These are holding up well on some thin steel I’m drilling through for a model project. The black oxide coating seems to be keeping the chips from clogging, which was my main worry.
