Dormer Pramet A553 11.30 mm HSS-E TIALN-TOP STRAIGHT SHANK COOLANT FEED X5D DRILL DIN 6535 HA

The Dormer Pramet A553 drill is a robust, 11.30 mm diameter HSS-E drill designed for precision work across a range of metals. With a straight shank and coolant feed, it’s built for reliable registration and steady performance in production environments as well as workshop settings. Its versatility makes it suitable for drilling steel, aluminium, and stainless steel with consistent results.

A 130-degree thinned point ensures self-centering and lowers the push force required to start a hole, helping you achieve clean starts with fewer jams or wandering. The TiAlN-TOP coating extends tool life and enhances performance when drilling harder materials, while convex cutting edges paired with coolant feed improve chip breakage and removal. This combination supports higher cutting speeds and feeds without sacrificing hole quality.

• Self-centering 130° thinned point: promotes accurate hole initiation and reduces startup effort for clean, true holes
• TiAlN-TOP coating for longer life: increases wear resistance and performance in harder materials, extending tool life
• Convex cutting edges with coolant feed: enhances chip control and removal at higher speeds/feeds for reliable, smooth drilling

Designed for reliability and consistent results, this drill delivers high-quality, accurate holes even at elevated speeds and feeds, with tight tolerances (H9). The premium HSS-E material and DIN 6535 HA straight shank make it a dependable choice for everyday production and demanding projects alike, helping you finish tasks faster with fewer tool changes.
