Dormer Pramet A620 5.50 mm HSS-E STRAIGHT SHANK STAINLESS STEEL STUB DRILL X2.5D DIN 1897

The Dormer Pramet A620 5.50 mm HSS-E Straight Shank Stub Drill is engineered for high-performance drilling in stainless steel and other tough materials. Built around a 5.50 mm diameter and a straight shank, this tool delivers reliable, precise holes in confined spaces, supported by the enhanced heat resistance and durability of HSS-E (high-speed steel with cobalt).

• 5.50 mm HSS-E cobalt alloy for durability: Delivers improved heat resistance and longer edge life when drilling stainless steel and hard alloys, helping maintain sharpness and reduce tool changes.
• Stub length for rigidity and precision: The compact flute length minimizes deflection and chatter, producing accurate, clean holes even in challenging workpieces.
• DIN 1897 compliance with 2.5xD depth ratio: Ensures consistent geometry and predictable performance in tight spaces, enabling efficient drilling and repeatable results across jobs.

Choose this drill to streamline workflows and gain confidence on demanding tasks. The combination of cobalt-enhanced HSS, a rigid stub form, and DIN-standard geometry delivers reliable hole quality, fewer reworks, and smoother setup in stainless steel and other tough materials. Whether you’re in a machine shop or a field workshop, it helps you finish precision work faster with consistent results.
