The Dormer Pramet A777 0.55 mm HSS-E Straight Shank Jobber Drill (DIN 338) is a precision small-diameter drill designed for metalworking where tight hole tolerances matter. With a 0.55 mm diameter and a straight shank, it fits easily into standard drill chucks and holders, making it a reliable choice for engineers, machinists, technicians, and hobbyists tackling delicate or pilot-hole work.

Its 135-degree split point, bronze oxide finish, and premium HSCO material work together to deliver self-centering starts, reduced friction, and broad material compatibility for clean, accurate holes across steel, aluminium, and stainless steel. This combination is designed for durability in demanding applications where consistency is key.

135° split point: Self-centering start with reduced push force, helping prevent wandering and enabling cleaner holes on the first pass.
Bronze oxide finish: Minimizes sticking of workpiece material to the cutting edge and improves chip flow, reducing rework and extending edge life.
Premium HSCO material: Delivers versatile performance across metals (steel, aluminium, stainless) with enhanced heat resistance and longer tool life.

With these design traits, the A777 drill supports quicker setups, more consistent hole quality, and fewer interruptions in busy workshops. Its DIN 338 straight-shank form, combined with robust materials, provides dependable performance from first hole to last, making it a trusted choice for precise, repeatable results in both professional and DIY environments.
