Dormer Pramet A110 2.20 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Introducing the Dormer Pramet A110 2.20 mm HSS straight shank long-series drill, engineered for precision metalwork and reliable, repeatable holes. Built to DIN 340 standards, this micro-diameter drill combines a robust construction with thoughtful design to deliver clean starts and consistent results across a range of materials.

• 118° conventional point — a strong, self-centering tip that bites quickly into the workpiece and stays sharp longer. It’s easy to re-grind, helping you extend tool life without sacrificing accuracy.
• Steam oxide finish — a friction-reducing coating that minimizes workpiece sticking at the cutting edge, reducing chatter and improving hole finish in many metals.
• Long length series — designed for deeper holes and applications where reach matters. The extended flute length provides ample clearance while maintaining rigidity for straight, true drilling.
• Premium HSS material — versatile enough for drilling steel, aluminum, and stainless steel, delivering dependable performance across common workshop materials.
• Straight shank — universal compatibility with a wide range of hand-held drills and machine chucks, ensuring straightforward setup and stable cutting
• DIN 340 compliance — trusted dimensional standards that ensure reliable interchangeability with compatible drill systems and fixtures.

Who benefits most: machinists, hobbyists, and fabrication professionals who need precise, small-diameter holes in metal with predictable behavior. This A110 drill shines in delicate pilot holes, thin-walled components, electrical enclosures, and intricate assemblies where accuracy and control are paramount.

Use scenarios and tips for best results:

• Apply light, steady feeds and moderate speeds to maximize life and edge quality on steel, aluminum, and stainless steel.
• Use cutting fluid or light lubrication to further reduce heat and extend edge life on harder materials.
• Start with a pilot hole if working in harder alloys to guide the bit and prevent wandering.
• Cool and inspect after use; resharpen when you notice any chipping or dullness to maintain drilling accuracy.
