Dormer Pramet A553 11.00 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

The Dormer Pramet A553 11.00 mm HSS-E drill with TiAlN-TOP coating is built for professionals who need reliable, repeatable holes across a range of materials. Featuring a straight shank and coolant feed, it is compatible with standard chucks and coolant systems, helping you maintain consistent performance in both workshop and production environments. Its design supports high-quality, precise holes with tight tolerances (h9) for demanding applications.

A 130° thinned point aids self-centering and reduces the push force at start, helping you begin holes smoothly and with less effort. The TiAlN-TOP coating extends tool life and sustains performance when drilling tougher materials, while the convex cutting edges paired with coolant feed improve chip breakage and removal. Together, these features enable higher cutting speeds and feeds without sacrificing hole integrity or accuracy.

• 130° Thinned Point for Easy Start: The precision point centers quickly and minimizes starting resistance, delivering clean entry and smoother hole initiation.
• TiAlN-TOP Coating for Longer Life: The coating shields the drill from wear, extending service life and maintaining sharpness when drilling steel, aluminium, and stainless steels.
• Convex Cutting Edges with Coolant Feed: Optimized edge geometry and integrated coolant delivery improve chip control and evacuation, supporting higher speeds and feeds with consistent hole quality.

This drill is a versatile, high-performance choice for everyday fabrication and precision hole-making. It combines reliable HSS-E substrate performance with advanced coatings and geometry to deliver accurate, consistent results, reduce downtime, and support efficient workflows across various materials and applications.
