• Teeth: 6 cutting edges for efficient material removal
• Depth of cut: 6 mm
• Overall length: 57 mm
• Shank: 10 mm combi shank with Weldon flat and threaded end (screwed shank)
• Standard: DIN 851
• Material: HSS-E cobalt-based with bright finish
• Helix angle: 15° for smooth cutting and good chip evacuation
• Rake angle: 10° to optimize cutting forces
• Compatibility: suitable for T-slot milling in steel, cast steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys

Designed to create clean, accurate T-slots for fixtures, nuts, and bolts, this cutter excels in demanding environments where durability and precision matter. The cobalt-based HSS-E construction offers enhanced wear resistance and heat tolerance, helping extend tool life in tough materials. The 15° helix and 10° rake angle work together to reduce cutting forces and improve surface finish, while the DIN 851 compatibility ensures seamless integration with standard tooling setups. Ideal for machine shops and production environments, it supports reliable performance across a range of common engineering materials.
