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

#56 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度分裂點設計,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達到最佳鑽孔性能。黑色氧化表面處理提供更高的耐磨性和耐腐蝕性。

      Emily L. ★★★★★

      These tiny #56 bits are perfect for my hobby electronics projects, and the black oxide coating seems to give them a good grip in the chuck. I've used three so far on brass and thin steel without any breakage or dulling.

      Andrew ★★★★★

      Tiny #56 bits, but the black oxide finish means they don't skate around on slick metal like my old bright-finished ones did. Punched through a steel bracket cleanly on the first try, and the 12-pack means I've got spares when I inevitably snap one.

      Julian Z. ★★★★★

      Bought these to restock my workshop and the black oxide coating seems to be holding up well even after several uses in hardwood. The 12-pack covers the common sizes I need for most jobs, so I don't have to hunt for individual bits.
