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

#18 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。

Customer Reviews (4.8 / 5 · 5 reviews)

Ryan W. ★★★★★

The black oxide coating on these #18 bits seems to grip the steel better than the plain ones I've used before. I put one through twelve holes in a 1/4-inch plate with no binding or breakage. They're a solid buy for the price.

Grace O. ★★★★★

Finally got a set that actually holds an edge through metal studs and conduit. The black oxide coating seems to keep them from grabbing and smoking like the cheaper ones I've used. So far all 12 bits have stayed sharp after a couple weeks of framing work.

Jason ★★★★★

Had to replace a bunch of worn-out bits on the jobsite, and these black oxide ones bite into steel nicely without walking. The 12-pack is great for keeping spares handy, and the #18 size is exactly what we needed for pilot holes.
