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

#57 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.

A 135 度分離點設計，可防止搖晃、滑動或偏移，並無需使用中心沖。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與抗腐蝕性。
