The Dormer Pramet A777 0.50 mm HSS-E Straight Shank Jobber Drill (DIN 338) is a precision small-diameter drill designed for clean, accurate holes in metal. With a 0.50 mm diameter and straight shank, it excels in tight spaces and micro‑machining tasks across steel, aluminium, and stainless steel.

Its 135-degree split point improves self-centering and reduces starting push force for less wandering and faster starts. The bronze oxide finish minimizes built-up edge by preventing workpiece material from sticking to the cutting edge, helping you maintain a smooth cut and longer tool life. Crafted from premium HSCO material, this drill delivers versatile performance across a wide range of materials—including steel, aluminium, and stainless steel—and it is designed for demanding applications with a heavy-duty build.

  • 135 Degree Split Point: Self-centering and reduces push force, helping start holes accurately and minimize wandering.
  • Bronze Oxide Finish: Prevents sticking and built-up edge, promoting smoother cuts and longer tool life.
  • Premium HSCO Material: Broad material compatibility (steel, aluminium, stainless steel) with enhanced wear resistance for durable, reliable drilling.

These features help you achieve consistent hole quality, reduce deburring and rework, and improve overall drilling efficiency across a range of metals and applications.
