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

#41 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度分割點設計,可防止搖晃、偏移或滑動,並無需預先打孔。這些鑽頭由M2高速鋼製造,並經熱處理,以確保延長使用壽命並獲得最佳鑽孔性能。黑色氧化表面處理提供更高的耐磨性和耐腐蝕性。

      Elizabeth ★★★★★

      Needed a #41 bit for a tiny pilot hole and the black oxide finish kept it from skating on the metal surface. It cut through cleanly without any binding, and having a dozen of these means I won't be running to the store for a while.

      Robert V. ★★★★★

      The black oxide coating on these bits seems to hold up better than the plain steel ones I’ve used before, and the #41 size is perfect for my precision model work. I've already gone through a couple of holes in aluminum without any chipping.

      Jacob ★★★★★

      Twelve bits in one pack is the reason I grabbed these, and I've already dulled two on a metal bracket without a single snap. The black oxide coating seems to help them hold up better than the shiny cheap ones I used before.
