Dormer Pramet A620 2.90 mm HSS-E STRAIGHT SHANK STAINLESS STEEL STUB DRILL X2.5D DIN 1897

The Dormer Pramet A620 2.90 mm HSS-E Straight Shank Stub Drill is engineered for high-performance drilling in stainless steel and other tough materials. With a 2.90 mm diameter, this stub drill is ideal for precision holes in confined spaces where accuracy matters.

Made from HSS‑E (high-speed steel with cobalt), it offers superior heat resistance and durability. The stub length provides exceptional rigidity, reducing deflection for clean, accurate holes even in demanding applications. Designed to DIN 1897 standards, this drill features a 2.5xD depth ratio for precise work in limited spaces.

• HSS‑E cobalt alloy for heat resistance: Extends tool life and maintains sharp cutting edges when drilling stainless steel and other hard materials, reducing wear-related downtime.
• Rigid stub design: Stub length minimizes deflection and chatter, delivering consistent hole size and better surface finish in tight or awkward setups.
• DIN 1897 compatibility with 2.5D depth: Ensures reliable mounting on standard machines and controlled drilling depth for precision in space-constrained work.

This drill supports efficient, repeatable results across demanding machining tasks. The cobalt-enriched HSS, combined with a stiff stub geometry and standard DIN sizing, helps engineers, builders, and technicians achieve accurate holes with fewer passes, smoother finishes, and dependable performance in stainless steel and other tough materials.
