Meet the Dormer Pramet A940 8.20 mm HSS-E Long Series Drill — a high‑performance, multi‑use drill designed for demanding metalworking tasks where precision and depth matter. Built for consistently clean starts and dependable hole quality, this tool is engineered to elevate productivity in professional shops and engineering environments.

Precise starting and reduced thrust — the 130° point is engineered to self‑center and minimize push force, helping you plunge into material with less wandering and more control. This translates to smoother starts, fewer reworks, and faster cycle times on every hole.

Bright finish for smoother cuts — the polished, bright surface reduces material adhesion on the cutting edge, promoting cleaner cuts and less built‑up edge during high‑speed drilling. The result is steadier feeds and fewer chip‑related interruptions.

Parabolic flute design for deep holes — a distinctive parabolic web and parabolic flute geometry enable deeper hole drilling in a single pass. When you need 10xD or more of depth without pecking, this geometry helps maintain chip evacuation and consistent hole geometry, even in tougher materials.

Premium HSS‑E (5% Co) for versatility — made from cobalt‑based HSS‑E, this drill handles a wide range of materials, including steel, aluminum, and stainless steel, with improved wear resistance and thermal stability. It’s built for high performance at competitive speeds and feeds, delivering reliable hole quality across different job lots.

Long series, straight shank, DIN/ANSI compatibility — designed as a long series PFX drill with a straight cylindrical shank, this tool aligns with DIN/ANSI standards for dependable interchangeability. The extended flute and overall length provide reach in deep pockets and thick workpieces, making it ideal for engineered components and assemblies.

This drill is particularly well suited for environments where speed, accuracy, and hole tolerance matter. Expect high‑quality, repeatable holes with tight tolerances (H10) and excellent surface finish, even when transitioning between materials like mild steel, stainless steel, and aluminum. For shops performing precision drilling, automotive fabrication, machine‑building, or general engineering tasks, the A940 8.20 mm HSS‑E long series drill is a reliable workhorse that reduces tool changes and keeps production moving.
