The Dormer Pramet A553 8.50 mm HSS-E TiAlN-TOP straight shank drill with coolant feed is a high‑performance holemaking tool designed for reliable, precise drilling across a range of metals. The straight shank (DIN 6535 HA compatible) fits standard drill chucks with ease, making it a practical choice for workshops, fabrication shops, and production environments.
A 130° thinned point helps the drill start cleanly and self‑center, reducing the push force required and minimizing wandering during initial engagement. The TiAlN‑TOP coating extends tool life and enhances performance when drilling harder materials, while convex cutting edges with coolant feed improve chip breakage and removal. This combination supports higher cutting speeds and feeds, delivering consistently clean holes with tight tolerances (H9) across steel, aluminium, and stainless steel.
- 130° Thinned Point for Self-Centering: Starts holes with minimal wandering and lower operator effort, improving first‑pass accuracy.
- TiAlN-TOP Coating for Longer Life: Increases tool life and sustains performance when drilling harder materials such as stainless steel and high‑strength alloys.
- Convex Cutting Edges with Coolant Feed: Enhances chip control and removal, enabling higher speeds/feeds without overheating for cleaner, more consistent holes.
Designed to deliver reliable, precise drilling across steel, aluminium, and stainless steel, this drill minimizes downtime and rework by providing clean starts, stable hole sizes, and effective heat management. The premium HSS‑E core, combined with TiAlN‑TOP coating, ensures dependable performance from production runs to demanding one‑off jobs, while the straight shank supports quick, confident tool changes in standard equipment. For professionals and serious hobbyists who demand repeatable results and efficient workflows, this drill is a dependable choice that helps you complete projects faster with professional‑quality holes.
