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

#30 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,並省去預先打孔的需求。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。

Nicholas J. ★★★★★

The black oxide coating on these is no joke—they’ve chewed through a dozen holes in steel without a single bit of chatter or dulling. The jobber length gives me just enough reach for tight spots, and the 12-pack means I can stop worrying about snapping one mid-project.

Steven C. ★★★★★

I’ve been using these #30 drill bits for a few weeks now, and the black oxide coating hasn’t shown any wear even after going through some tough steel. The 12-pack gives me plenty of backups, which is handy for my smaller precision hole work.

Abigail ★★★★★

The black oxide finish really helps these bits bite into steel without wandering, and I’ve gone through a dozen holes on a single bit so far. Good value for a 12-pack of a common size like #30.
