Dormer Pramet A553 12.50 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

The Dormer Pramet A553 12.50 mm HSS-E drill with TiAlN-TOP coating and a straight shank is engineered for dependable, high-precision metal drilling. With a 12.50 mm diameter, DIN 6535 HA straight shank, and coolant feed, it delivers consistent hole quality across a wide range of materials—including steel, aluminium, and stainless steel—while achieving precise H9 hole tolerance.

Its 130° thinned point promotes easy starts, self-centering, and reduced push force. The TiAlN-TOP coating extends tool life and improves performance when drilling harder materials. Convex cutting edges with coolant feed enhance chip breakage and removal, enabling higher speeds and feeds while maximizing tool life. Constructed from premium HSS-E material, this drill handles a broad spectrum of metals with reliable results.

• 130° Thinned Point for Easy Start and Self-Centering: The 130-degree thinned point helps with self-centering and reduces the push force required when starting holes.
• TiAlN-TOP Coating for Extended Life: Titanium Aluminium Nitride coating increases tool life and improves performance when drilling harder materials.
• Convex Cutting Edges with Coolant Feed for Efficient Chip Control: Convex edges with coolant feed improve chip breakage and removal, maximizing tool life and enabling higher cutting speeds and feeds.

This combination translates to faster, more reliable drilling—fewer reworks and longer tool life—across common metals. The drill maintains hole quality at higher speeds, supports production-friendly setups with its straight shank and DIN 6535 HA compatibility, and delivers consistent performance that engineers, machinists, and hobbyists can trust for demanding applications.
