Dormer Pramet A620 3.00 mm HSS-E STRAIGHT SHANK STAINLESS STEEL STUB DRILL X2.5D DIN 1897

The Dormer Pramet A620 3.00 mm HSS-E Straight Shank Stub Drill is designed for precision drilling in stainless steel and other challenging materials. Made from HSS-E (high-speed steel with cobalt), it delivers excellent heat resistance and durable performance under demanding conditions. Its stub length enhances rigidity, reducing deflection for clean, accurate holes even in tight or awkward setups. Built to DIN 1897 standards with a 2.5xD depth ratio, this drill is ideal for precise work in spaces where control and reliability matter.

Whether you’re a professional machinist, a maintenance technician, or a dedicated hobbyist, this 3.00 mm drill provides dependable performance, straightforward setup, and consistent hole quality across tough metals and alloys.

• Rigid stub geometry: Minimizes deflection and chatter to produce straighter holes with tighter tolerances, improving hole quality and finishing consistency.
• HSS‑E with cobalt for durability: Enhanced heat resistance and wear resistance extend tool life in high-temperature drilling, reducing tool changes and downtime.
• DIN 1897 compatibility with 2.5xD depth: Optimized for work in restricted spaces, delivering precise, repeatable hole depths and reliable chip evacuation for challenging parts.

This combination of rigidity, advanced material composition, and standardized sizing translates into reliable everyday performance: straighter holes, fewer deflections, longer tool life, and a smoother workflow from setup to finished part.
