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

#3 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,可防止晃動、偏移或滑動,並免除預先打孔的需求。這些鑽頭由 M2 高速鋼製成,並經過熱處理,以確保延長使用壽命和最佳切割效能。黑色氧化物表面處理提供更高的耐磨性和腐蝕抵抗力。

Henry ★★★★★

For the price of a single specialty bit at the hardware store, I got a whole box of #3s that have handled everything from steel brackets to brass without dulling. The black oxide coating seems to be doing its job, and the 12-pack means I don't panic when one snaps.

Edward ★★★★★

These are my go-to bits now for metal work; the black oxide coating really does cut through without grabbing, and the 12-pack means I always have a spare when one finally snaps. The jobber length gives me enough reach for most holes without flexing.

Scarlett N. ★★★★★

Punched through some tough steel shelf brackets without any wandering, and the black oxide coating looks like it'll hold up well. Nice having a dozen of these in a compact case, too.
