Dormer Pramet A110 2.10 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Engineered for precision and reliability, the Dormer Pramet A110 2.10 mm HSS Straight Shank Long Series Drill (DIN 340) delivers consistent performance for deep-hole drilling tasks in both handheld and machine setups. This compact, small-diameter drill pairs a robust tip with extended reach, making hard-to-access holes achievable with clean, accurate results.

Key features that drive precision and productivity

• 118° conventional point provides a strong, self-centering tip that starts true and tracks straight. The geometry is designed to hold an edge and is easy to re-grind to extend tool life between replacements.
• Steam oxide finish reduces friction and prevents workpiece material from sticking to the cutting edge, resulting in smoother holes and easier chip evacuation across metals like steel, aluminium, and stainless steel.
• Long length series delivers extended reach for deep-hole drilling and applications where access is limited. The straight shank preserves rigidity and ensures compatibility with a wide range of chucks and collets.
• Premium HSS material stands up to heat and wear, making this drill suitable for drilling a variety of materials—from alloys in steel to light aluminium workpieces and stainless steels.
• DIN 340 compliant design guarantees consistent diameter, tolerance, and interchangeability with standard tooling in professional workshops.
• Versatility in one tool ideal for both hand-held drilling and machine-driven operations, enabling precise small-diameter holes in multiple setups without switching tools.

Practical use cases

Pro tips for best results

• Use a suitable cutting fluid or coolant when drilling metals to maximize tool life and ensure a smoother cut.
• Mark a center point or punch a starter spot to prevent wandering, then begin with a light feed and increase gradually as the bit engages the material.
• Maintain steady RPM appropriate for the material and diameter, and periodically back the drill out to clear chips and prevent binding.
• After drilling, deburr the hole for a clean finish and to protect any mating parts from edge burrs.
