#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.

135 度分叉點設計,可防止晃動、偏移或滑動,無需預先打孔。這些鑽頭採用 M2 高速鋼製造,並經過熱處理,以確保延長使用壽命並達到最佳鑽孔效能。黑色氧化處理提供更高的耐磨性和耐腐蝕性。

      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.
