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

#43 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,可防止鑽頭晃動、偏移或滑動,無需預先打孔。這些鑽頭由M2高速鋼製成,並經熱處理,以確保延長使用壽命和最佳切削性能。黑色氧化物表面處理提供了更高的耐磨性和耐腐蝕性。

      Mia ★★★★★

      Twelve bits for the price of a few singles is a solid deal, and the black oxide coating seems to be holding up fine after a dozen holes in mild steel. The jobber length gives me enough reach in tight spots without wandering.

      William ★★★★★

      Bought the 12-pack because I keep snapping my small bits, and having spares on hand is a relief. The black oxide finish seems to hold up fine drilling through mild steel plate. All twelve came sharp and straight in the case.

      Ella Z. ★★★★★

      Used these for pilot holes on a cabinet build and they cut clean through oak without wandering. The black oxide coating seems to hold up better than the shiny bits I had before. Having 12 of the same size means I'm not stopping mid-project when one dulls.
