Dormer Pramet A553 11.50 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

The Dormer Pramet A553 11.50 mm HSS-E TiAlN-TOP straight shank drill with coolant feed is built for reliable, high-precision hole making across a range of materials. Its 130° thinned point promotes self-centering and reduces the push force required to start cutting, helping you achieve clean starts and accurate holes with less effort.

Designed for versatility and long life, this drill uses premium HSS-E base material with a TiAlN-TOP coating to extend tool life and maintain performance when drilling tougher materials. The coolant feed, combined with convex cutting edges, improves chip control and removal, enabling higher cutting speeds and feeds without sacrificing edge life or hole quality.

• 130° Thinned Point for Self-Centering: Guides the drill into the workpiece smoothly, improves starting accuracy, and reduces the force needed to begin cutting, leading to cleaner holes and faster setups.
• TiAlN-TOP Coating for Longer Tool Life: The coating reduces wear and heat build-up, delivering extended service life and better performance when drilling harder materials like steel and stainless.
• Convex Cutting Edges with Coolant Feed: Enhanced chip breakage and removal with active coolant, allowing higher speeds and feeds while preserving tool life and hole finish.

This drill is capable of delivering high-quality, accurate holes at high speeds and feeds, achieving precise H9 hole tolerances with a reliable straight-shank design. Ideal for engineers, machinists, and hobbyists alike, it supports efficient workflows, reduces downtime, and helps you achieve consistent results across a variety of materials.
