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

#60 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,可防止鑽頭晃動、偏移或滑動,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並達到最佳切削性能。黑色氧化處理提供更高的耐磨性和抗腐蝕性。

    John F. ★★★★★

    Been using these #60 bits for circuit board work and they're precise enough to hit tiny pads without wandering. The black oxide coating holds up well through several holes in FR4, and the 12-pack means I won't run out mid-project.

    Joseph ★★★★★

    The black oxide finish on these #60 bits seems to hold up well against heat, and the jobber length gives just enough reach for tight spots. I drilled through some model parts without any wobble or binding.

    Evelyn ★★★★★

    I've been using these #60 bits for some precise PCB work and they fit perfectly in my pin vise without any wobble. The black oxide coating seems to hold up well through several holes in fiberglass board. A solid 12-pack at this price point.
