Maintenance Drill Bits are a versatile tool designed for drilling various materials with ease. Constructed from high-quality cobalt material, they provide enhanced durability and wear resistance while reducing chipping or breaking when coming into contact with hardened materials such as stainless steel, cast iron, and tool steel. With a 135 degrees point angle, these drill bits offer an aggressive tip that starts on contact for faster penetration without skidding or wandering. Their 4mm size (0.157 inches) makes them ideal for precision drilling while the hex shank provides secure grip when in use. With a high-speed steel finish, they maintain their sharpness longer, resulting in smooth, clean holes even in challenging applications. These bits are widely used in automotive repair and maintenance industries, plumbing repairs, woodworking projects or any application requiring precise drilling into various materials.
