Dormer Pramet C922 14.0mm HSS-E-Powder Metal Alcrona Primax Flatted Shank Multi-Flute Roughing (HRA) Standard Length End Mill DIN 844 K

The Dormer Pramet C922 14.0 mm HSS-E-Powder Metallurgical End Mill is a short-series roughing tool built for high-load milling in demanding metals. Designed for shoulder milling, slot milling, and ramping, it delivers consistent performance in alloy and tool steels, stainless steel, cast iron, and copper alloys.

• Diameter: 14.0 mm
• Length of cut: 26 mm
• Overall length: 83 mm
• Reach with neck relief: 37.5 mm
• Shank: Weldon 12 mm
• Material & coating: HSS-E powder metallurgy with Alcrona Primax coating
• Flutes: 3-flute configuration
• Cutting geometry: HRA asymmetrical fine-pitch profile; 35° helix and 12° rake
• Standards: DIN 844 K
• Applications: Shoulder milling, slot milling, ramping in various metals

The tool’s HRA asymmetrical fine-pitch profile minimizes chatter and promotes steady material removal even under aggressive roughing passes. The 3-flute design balances rapid chip clearance with robust chip formation, supporting higher feed rates while maintaining control. Powder-metallurgical HSS-E combined with the Alcrona Primax coating delivers improved hardness and wear resistance, extending tool life in abrasive alloys and high-temperature materials. A 35° helix enhances chip evacuation, while the 12° rake reduces rubbing on shoulders and ramps, contributing to better surface finish and longer tool life. With a 12 mm Weldon shank and DIN 844 K compatibility, it fits standard tool holders and supports efficient integration into existing setups. This end mill is ideal for operators needing reliable roughing performance across alloys, stainless steels, cast iron, copper alloys, and high-temperature alloys, delivering predictable results from pocketing operations to deep-slot work.
