Dormer Pramet A553 8.00 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

The Dormer Pramet A553 drill is an 8.0 mm HSS-E drill with a straight shank and coolant feed, designed for fast, reliable hole making across a variety of metals. Its 130° thinned point helps with self-centering and reduces the push force required to start cutting, delivering quicker setup and cleaner starts.

This high-performance drill features a Titanium Aluminium Nitride (TiAlN-TOP) coating that extends tool life and enhances performance when drilling harder materials. Built to DIN 6535 HA standards, it combines strength with precision to maintain accuracy at higher speeds and feeds.

• 130° thinned point: Promotes self-centering and reduces starting resistance, enabling quicker, more accurate hole starts.
• TiAlN-TOP coating: Increases service life and sustains performance on harder materials, reducing tool changes and downtime.
• Convex cutting edges with coolant feed: Improves chip breakage and removal, supports higher speeds and feeds, and extends overall tool life.

Designed for versatile use—drilling steel, aluminium, and stainless steel with high precision—the A553 delivers consistent hole quality with h9 tolerance. Its combination of self-centering geometry, durable coating, and efficient coolant delivery helps you complete jobs faster, reduce rework, and maintain reliable results across demanding applications.
