Dormer A777 HSS-E Cobalt Jobber Drill Bits 16mm Pack of 1

Engineered for demanding professional and industrial applications, this 16mm Dormer A777 drill bit delivers exceptional durability and consistent cutting performance even in high-stress environments. The premium HSS-E cobalt construction provides superior heat resistance and edge retention, enabling efficient drilling in tough materials such as stainless steel, alloy steels, and hardened metals. With a 135-degree split point, the bit starts cleanly without wandering, reduces thrust force, and ensures accurate hole positioning every time. The advanced geometry also helps to break chips effectively, minimising jamming and prolonging tool life.
