Dormer Pramet A413 M10 HSS ST STRAIGHT SHANK STEP 180 DEG SHORT SERIES (X2.5D) DRILL

The Dormer Pramet A413 M10 HSS ST STRAIGHT SHANK STEP 180 DEG SHORT SERIES (X2.5D) DRILL is designed to streamline hole preparation by drilling and counterboring in a single operation. Its 118-degree pilot and 180-degree counter bore create clean clearance pockets for standard metric threads, making it ideal for assemblies, fastener installations, and mating parts. Compatible with both CNC and conventional machines, this tool suits a wide range of production environments.

Built from premium High-Speed Steel and finished with a steam oxide coating, this drill resists sticking and built-up edge, helping you maintain sharp cutting edges and consistent hole geometry across materials, including steel, aluminium, and stainless steel. The straight shank and compact short-series form deliver reliable rigidity and ease of use in busy workshops.

• 118° Pilot with 180° Counter Bore: Enables drilling and counterboring in one pass to create a precise clearance hole for standard metric threads, reducing setup time and improving throughput.
• Steam Oxide Finish for Smooth Cutting: Minimizes material sticking to the edge and improves chip flow, extending tool life and delivering cleaner holes across steel, aluminium, and stainless steel.
• Premium HSS for CNC and Conventional Machines: Designed for versatile use in both CNC and traditional machines, with broad material compatibility (steel, aluminium, stainless steel) and dependable, repeatable performance.

This drill helps you complete clearance-hole tasks quickly and reliably, reducing rework and downtime while delivering consistent hole depth and diameter. Its robust HSS construction and protective surface finish give you confidence in everyday production, whether you’re outfitting a CNC mill or a manual drill press. The result is smoother setups, fewer tool changes, and dependable performance across a variety of materials.
