Dormer Pramet A553 5.50 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

Introducing the Dormer Pramet A553 5.50 mm HSS-E drill with a straight shank and coolant feed. This high-performance tool is designed for professionals and hobbyists alike, delivering precise, high-quality holes in steel, aluminium, and stainless steel—even at higher speeds. The 130° thinned point promotes self-centering and reduces the push force at entry for smoother starts.

• 130° Thinned Point for Self-Centering and Easy Starting: The 130° thinned point helps the drill find its center and reduces the force required to start, minimizing wander and improving hole alignment.
• TiAlN-TOP Coating for Longer Tool Life: The premium HSS-E material paired with Titanium Aluminium Nitride coating delivers exceptional wear resistance, enabling drilling across steel, aluminium, and stainless steel with reduced wear and heat, even at higher speeds.
• Convex Cutting Edges with Coolant Feed for Superior Chip Breakage and Removal: The convex edge geometry, combined with coolant delivery, breaks chips more effectively and evacuates them quickly, enabling higher speeds and longer tool life.

This drill is built to boost your productivity by combining precision, durability, and versatility. The self-centering point reduces rework and startup delays, while the TiAlN-TOP coating and HSS-E core deliver reliable performance across common metals. With efficient chip control and coolant-assisted cutting, you can maintain higher feeds and speeds without compromising hole quality, achieving precise h9 hole tolerance and reducing downtime across workshops, fabrication shops, and production lines.
