Dewalt 21/64 in. Black Oxide Jobber Drill Bit

The Dewalt 21/64 in. Black Oxide Jobber Drill Bit is engineered for durability, wear resistance, and long-lasting performance. Featuring a black oxide finish, this drill bit provides enhanced lubricity and resistance to corrosion and wear during heavy drilling applications. Designed with a 135-degree split point tip, this bit minimizes walking on contact for clean, accurate hole starting. The parabolic flute design promotes efficient chip removal, while the tapered web and patented core diameter deliver increased strength and resistance against bit breakage.
