Tungsten Carbide 12mm 2-Flute Square End Mill For Steel/Stainless Steel CNC Milling Tool AlTiN Coated

Tungsten Carbide 12mm 2-Flute Square End Mill For Steel/Stainless Steel CNC Milling Tool AlTiN Coated

Introduction:

Our 12mm 2-flute square end mill combines premium micro-grain tungsten carbide with advanced AlTiN coating to deliver exceptional performance in steel and stainless steel machining. Engineered for CNC milling centers, this tool provides optimal chip evacuation and extended tool life in slotting, profiling, and side milling operations. The precision-ground geometry ensures ±0.01mm runout accuracy for high-tolerance applications.

Features:

✔ High-Quality Carbide Substrate

• 0.5μm ultra-fine grain tungsten carbide

• 10% cobalt binder for enhanced toughness

✔ Advanced AlTiN Coating

• 3μm coating thickness for maximum wear resistance

• 1,100°C oxidation resistance

• Reduces friction by 30% vs. uncoated tools

✔ Optimized 2-Flute Design

• 35° helix angle balances cutting force and chip removal

• Center-cutting capable for plunge milling

• Polished flutes prevent chip adhesion

✔ Precision Manufacturing

• Grinding accuracy: ±0.005mm

• Dynamic balance: G2.5 grade

• h6 shank tolerance for perfect collet grip

Advantages:

▶ 5X Longer Life vs standard TiN-coated end mills in 304 stainless steel

▶ 20% Higher Feed Rates achievable in carbon steels

▶ Superior Surface Finish (Ra 0.4-0.8μm) reduces post-processing

▶ Consistent Performance maintains tolerance through entire tool life

Applications:
