This 3-flute tapered step forming cutter combines precision geometry with advanced coolant delivery for optimal aluminum machining. Designed as a solid carbide, uncoated tool with internal coolant channels, it excels in high-speed forming, profiling, and step-milling applications where coating-free cutting edges prevent aluminum adhesion.

• 3-Cutting Edge Design - Balanced 3-flute geometry reduces vibration while maintaining chip space with 30° spiral flutes for efficient chip evacuation
• Tapered Step Profile - Integrated step geometry eliminates tool changes for chamfering, deburring, and multi-diameter holes with 5°-15° customizable taper angles
• Internal Coolant System - 2-4 precision coolant holes (Ø1.2mm) direct lubricant to cutting edges, enabling 300% higher feed rates vs. external coolant tools
• Uncoated Micro-Grain Carbide - Special carbide grade optimized for non-ferrous materials with polished flute surfaces to minimize chip adhesion
• High-Rigidity Shank - Weldon flat shank (optional) prevents slippage in heavy cuts with h6 tolerance for precise collet/chuck mounting

• Aerospace - Wing rib profiling, fuselage components
• Automotive - Engine block lightening pockets, transmission housings
• Heat Sinks - Base plate milling and fin machining
• 3C Industry - Laptop chassis, smartphone frames

• Advanced grinding machines: All of our grinding machines are WALTER and SAACKE brands
• Advanced inspection machines: We have ZOLLER, OMEGA, PG1000 for inspecting each carbide tool
• Fast feedback: 24 hours online service
• Strict quality control: Three-stage inspection process (raw material, semi-finished, final pre-shipment)
