Dormer A777 HSS-E Cobalt Jobber Drill Bits 11.5mm Pack of 5

These Dormer A777 drill bits are engineered to deliver exceptional durability and precision in the most demanding professional and industrial applications. The high-speed steel (HSS) cobalt construction provides superior heat resistance and edge retention, making them ideal for drilling tough materials such as stainless steel, cast iron, and high-tensile alloys. With a carefully designed 135° split point, these bits start cleanly without wandering, reducing the need for pilot holes and improving drilling accuracy in high-stress environments.
