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

#55 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,並免除預先打中心孔的步驟。這些鑽頭以M2高速鋼製造,並經熱處理,確保延長使用壽命並達到最佳鑽孔效能。黑色氧化表面處理提供更高的耐磨性與抗腐蝕性。

      Robert ★★★★★

      Started drilling into some stainless steel brackets today and these #55 bits didn't even squeak, the black oxide coating clearly helped. After about a dozen holes they still feel sharp—no skipped or wandering tips. Solid pack for the price.

      Lucy ★★★★★

      The black oxide finish handled a full afternoon of drilling into steel without any chips peeling off, and the #55 size cut clean holes exactly where I marked them. I've already burned through cheaper bits in one sitting, so getting a full 12-pack of these feels like a solid deal.

      Natalie U. ★★★★★

      Grabbed these for some tight tolerance holes I had to drill and they cut cleanly right out of the pack without any wandering on start. The black oxide finish seems to hold up better than plain steel bits I've used before.
