• Reach with Neck Relief: 53.5 mm to access tight pockets and shoulders without rubbing
• Shank: 20 mm Weldon shank for secure retention and compatibility with standard collet systems
• Material & Coating: Powder metallurgical HSS-E with Alcrona coating for enhanced wear resistance
• Helix & Rake: 45° helix with 12° rake angle optimized for shoulder milling and ramping
• Standard: DIN 844 K specification for reliable interchangeability
• Applications: Shoulder milling, slot milling, and ramping across multiple metals
• Material Range: Suitable for plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper or copper alloys, and high-temperature alloys

This end mill is engineered to deliver steady, predictable performance in demanding milling workflows. The Alcrona coating reduces wear and heat buildup, extending tool life while maintaining a clean, consistent chip flow. The 4-flute design provides a good balance between material removal and surface finish, making it a dependable choice for precision milling on CNC machines. The combination of a Weldon shank and DIN 844 K compatibility ensures secure tool seating and straightforward replacement within standard tooling setups. Ideal for machine shops or maintenance environments that require reliable metal removal across a broad material spectrum.
