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

#28 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,可防止搖晃、偏移或滑動,並免除預先打孔的需要。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。

I needed a #28 bit for a small project and this 12-pack gave me plenty of extras, plus the black oxide coating seems to handle the heat well without binding up.

David ★★★★★

I’ve been drilling through some old hardwood shelves, and these black oxide bits bite in cleanly without walking—much better than the standard silver ones I used before. The set gives you a good range of sizes, and not one has snapped or dulled yet.

Chloe ★★★★★

These #28 bits are spot on for the size I needed, and the black oxide coating seems to hold up well against rust so far. They came in a sturdy plastic case, which I wasn't expecting but really appreciate for keeping everything organized. I've already used three of them on some mild steel and they cu
