3 Cutting Edge Tapered Step Forming Cutter Internal Coolant Carbide Tool Uncoated for Aluminum

Introduction:

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.

Features:

✔ 3-Cutting Edge Design

• Balanced 3-flute geometry reduces vibration while maintaining chip space

• 30° spiral flutes ensure efficient chip evacuation in gummy aluminum alloys

✔ Tapered Step Profile

• Integrated step geometry eliminates tool changes for chamfering, deburring, and multi-diameter holes

• 5°-15° taper angles (customizable) for smooth transitional cuts

✔ Internal Coolant System

• 2-4 precision coolant holes (Ø1.2mm) direct lubricant to cutting edges

• Enables 300% higher feed rates vs. external coolant tools

• Prevents built-up edge (BUE) in aluminum alloys

✔ Uncoated Micro-Grain Carbide

• Special carbide grade optimized for non-ferrous materials

• Polished flute surfaces minimize chip adhesion

• No coating = zero chemical affinity with aluminum

✔ High-Rigidity Shank

• Weldon flat shank (optional) prevents slippage in heavy cuts

• h6 tolerance for precise collet/chuck mounting

Advantages:

50% Longer Tool Life vs. coated tools in aluminum (no edge peeling)

Mirror Finishes (Ra ≤0.4µm) achievable with polished flutes

One-Tool Solution for drilling, tapering, and profiling
