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

#52 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,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和最佳切削孔性能。黑色氧化表面處理提供更高的耐磨性和耐腐蝕性。

      Sofia T. ★★★★★

      The black oxide coating held up nicely through a dozen holes in mild steel without any chipping. Each #52 bit came out of the pack sharp and seated snug in my pin vise, so the set feels like solid value for the price.

      Leo N. ★★★★★

      Used the #52 bits for a few small pilot holes in steel, and they held up better than my old ones. The black oxide finish seems to be reducing friction just like it should.

      Joseph ★★★★★

      Just used a couple of these bits to drill through some thin steel brackets, and the black oxide coating really helped them bite in without walking. They fit my drill chuck perfectly, so far no chips or dulling after several holes.
