Dormer Pramet A553 18.00 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

The Dormer Pramet A553 18.00 mm HSS-E drill with TiAlN-TOP coating combines robust performance with versatility for metalworking tasks. Featuring a straight shank and coolant feed, it fits standard toolholders (DIN 6535 HA) and is ready for reliable drilling in steel, aluminium, and stainless steel at speed.

Its 130° thinned point helps with self-centering and reduces the push force required at start, while the Titanium Aluminium Nitride coating extends tool life and improves performance when drilling harder materials. Convex cutting edges with coolant feed further enhance chip breakage and removal, enabling higher cutting speeds and feeds without sacrificing durability.

• 130° thinned point for self-centering: Starts holes cleanly and reduces starting resistance, speeding up setup and reducing wear at the initial cut.
• TiAlN-TOP coating for longer life: Increases tool life and maintains performance when drilling harder materials like stainless steel and hardened steels.
• Convex cutting edges with coolant feed: Improves chip control and removal, enabling higher speeds/feeds while protecting tool life and delivering consistent hole quality.

Designed to deliver high-quality, accurate holes at high speeds and feeds, this drill maintains tight tolerances (including h9 hole tolerance) across a broad material range. With premium HSS-E material and reliable geometry, it supports efficient production, fewer tool changes, and predictable results in demanding applications.
