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

#20 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,並免除預先打中心孔的步驟。這些鑽頭以M2高速鋼製造,並經熱處理,以確保延長使用壽命並提供最佳鑽孔性能。黑色氧化表面處理提供更高的耐磨性和耐腐蝕性。

Sofia ★★★★★

Picked up this 12-pack of #20 bits for a metalworking project, and the black oxide coating really helps keep them from walking on smooth surfaces. All twelve bits were sharp out of the box and held up well through several holes in mild steel.

Madison ★★★★★

The black oxide coating on these #20 bits really helps them stay sharp longer than standard ones I've used. Drilled through some tough steel without any binding or wandering.

Amelia A. ★★★★★

Been using these #20 bits in my shop for a few weeks now—the black oxide coating handles heat way better than my old set, and the 12-pack means I’ve got backups on the bench. Exactly what my drill press needed.
