• Length of cut: 10 mm
• Overall length: 60 mm
• Shank: Weldon (10 mm) for secure, repeatable clamping
• Material: HSS‑E with powder metallurgy for enhanced wear resistance and durability
• Finish: Bright finish to promote smooth cutting and reduced built‑up edge
• Helix angle: 30° for steady cutting and effective chip evacuation
• Rake angle: 12° to improve cutting action in shoulder milling and ramping
• Standard: DIN 327 D
• Applications: Slot milling, shoulder milling, and ramping in free machining and plain carbon steel, copper and copper alloys
• Series: Extra‑short length designed for reach in confined pockets without sacrificing rigidity

This tool is tailored for situations where space is limited but precision is critical. The PM‑HSS‑E construction offers improved wear resistance and heat tolerance, helping maintain diameter and edge integrity over longer runs. The combination of a 30° helix and a 12° rake angle aids smooth entry and efficient chip formation, reducing cutting forces and helping achieve cleaner slots and shoulders. With a Weldon shank and DIN 327 D compatibility, it fits standard holders and collets for reliable, repeatable performance in production environments and tool rooms alike.
