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

#19 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。

Brian K. ★★★★★

The black oxide coating held up surprisingly well through a dozen holes in steel without any chatter or dulling, and the #19 sizing was spot-on for my pilot holes. I’ve already burned through cheaper sets, but these still feel sharp when I grab them from the case.

George ★★★★☆

The black oxide finish seems to hold up well so far, and having a dozen in one pack means I won't run out mid-project. The point started true on the first few holes I drilled into mild steel, which was a pleasant surprise for this price.

Hazel B. ★★★★☆

Been reaching for these #19s constantly since they arrived, and the jobber length gives just enough reach for most of my work without flexing. The black oxide finish has already shrugged off a couple of hot passes through mild steel, so they're holding up better than the cheap ones I used before. On
