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

#49 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度分岔點設計,可防止晃動、偏移或滑動,並無需預先打孔。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和最佳切削效能。黑色氧化處理提供更高的耐磨和耐腐蝕性。

      Ellie ★★★★★

      These black oxide bits cut through the aluminum bracket I was drilling without any chatter, and the 12-pack covers most of the tiny sizes I reach for on small jobs. The finish seems more durable than standard HSS bits I've used before.

      Olivia Y. ★★★★★

      Just finished a small circuit board project and the 12-pack meant I had extras when I snapped one. The black oxide coating held up well against the brass I was drilling.

      Lily ★★★★★

      These #49 bits cut through steel like butter, and the jobber length gives me just the right reach for most tasks. I've already used four from the pack, and they're all holding up great with no chipping.
