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

#33 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,可防止鑽頭晃動、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。

      Ella L. ★★★★★

      Bought these for drilling pilot holes in oak and they cut through cleanly without wandering. The black oxide coating seems to be holding up fine after a dozen holes, no dulling yet. Having the exact #33 size on hand beats digging through a mixed set every time.

      Penelope ★★★★★

      Bought these for a furniture repair job and the black oxide coating really does seem to help them bite into metal without wandering. Getting 12 of the same size means I'm not stopping to resharpen halfway through a project. The jobber length is perfect for my drill press.

      Zoe ★★★★★

      Bought these for my hobby bench and the 12-pack means I'm not stopping mid-project when one dulls. The black oxide coating seems to be holding up fine drilling through mild steel plate.
