Dormer Pramet A110 7.00 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 7.00 mm HSS ST Straight Shank Long Series Drill (DIN 340) is engineered for precision, reach, and dependable performance when you need to drill deeper holes with confidence. This drill bit combines a robust 118‑degree point with a long, straight shank, making it ideal for both handheld and machine-driven applications across a range of metals.

• 118-degree conventional point — delivers a strong, self-centering tip that minimizes wander and regrinds cleanly for repeated use.
• Steam oxide finish — reduces friction and prevents workpiece material from sticking to the cutting edge, improving chip flow and reducing built‑up edge.
• Long length series — specifically designed for deep-hole drilling and tasks requiring extended reach without sacrificing rigidity.
• Premium high-speed steel (HSS) — versatile across materials including steel, aluminium, and stainless steel, delivering consistent hole quality and long tool life.
• Versatile for handheld and machine operations — a reliable choice for workshop tasks, fabrication lines, and production environments where depth and precision matter.

Use cases and practical tips — secure clamping is essential for long-reach drilling to prevent deflection. Start with a conservative feed and maintain steady speeds appropriate for the material. When drilling thicker sections or materials prone to grabbing, apply a light cutting fluid or oil to enhance chip evacuation and edge life. The 7.00 mm diameter is well-suited for through-holes, pilot holes for larger counts, or clearance openings in metalworking projects.
