• Flutes: 4-flute design for smooth cutting and steady chip evacuation
• Length of Cut: 15 mm
• Overall Length: 59 mm
• Shank: 6 mm Weldon shank for secure clamping and repeatable performance
• Material: Powder-metallurgical HSS-E with bright finish for improved hardening and wear resistance
• Helix Angle: 30° to promote efficient chip removal and smooth entry
• Rake Angle: 12° to optimize cutting in shoulder and slot milling
• Standard: DIN 844 L compliant for compatibility with standard tool holders
• Applications: Shoulder milling and slot milling in free machining steel, plain carbon steel, copper, and copper alloys

Benefits: The combination of HSS-E powder metallurgy and a bright finish delivers durability and reliable cutting performance in challenging materials. The 30° helix and 12° rake angle reduce cutting forces and minimize built-up edge, helping you achieve clean shoulders and precise slots. The long-series geometry provides reach into deeper pockets without compromising rigidity, while the 6 mm Weldon shank ensures secure, repeatable clamping in your milling spindle. Designed to meet DIN 844 L standards, this end mill pairs well with common tool holders, making it a dependable choice for workshops and production environments that demand consistency, accuracy, and versatility in small-diameter milling tasks.
