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

#48 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,並免除預先打中心孔的步驟。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。

      Riley ★★★★★

      Punched through a few 1/2" steel plates without any wobble—these bits stayed sharp and didn't snap like cheaper sets I've used. The jobber length is perfect for getting into tight spots, and the black oxide finish still looks new after a dozen holes.

      Claire C. ★★★★★

      The black oxide coating held up perfectly through a full weekend of PCB work, and the 12-pack means I finally have spares within arm's reach instead of hunting the garage. Jobber length gives just the right rigidity for clean holes in thin steel, no wobble or chatter.

      Richard ★★★★★

      I've been through a dozen of these #48 bits this month and they still cut clean without wandering. The jobber length gives me just enough reach for most of my PCB and brass work, and the black oxide coating seems to keep them from rusting in my damp garage.
