Product Description

AlTiN Tungsten Solid Carbide Bull End Mill High Efficiency Radius Inconel Cutter

The AlTiN-coated tungsten solid carbide bull end mill is a high-performance milling cutter designed for high-efficiency radius milling in demanding machining applications.

Key Features:

Material: Solid Tungsten Carbide (WC) provides exceptional hardness, wear resistance, and thermal stability, making it ideal for high-speed machining of tough materials like hardened steels, titanium, and superalloys.
Coating - AlTiN (Aluminum Titanium Nitride):
- Enhances tool life by reducing friction and heat buildup
- Excellent oxidation resistance, allowing for higher cutting speeds
- Ideal for dry or near-dry machining due to its heat-resistant properties
Bull Nose Design (Corner Radius):
- The rounded corner (radius edge) increases strength compared to sharp-edged end mills, reducing chipping and prolonging tool life
- Suitable for contouring, profiling, and semi-finishing/finishing operations
High-Efficiency Milling (HEM):
- Optimized for high-speed machining (HSM) and trochoidal milling strategies
- Reduces cutting forces, improving tool life and surface finish

Applications:

Aerospace (titanium, Inconel)
Mold & die machining (hardened steels)
General CNC milling of high-strength materials

Product Advantages

Longer tool life due to AlTiN coating and carbide substrate
Higher feed rates & speeds compared to uncoated or TiN-coated tools
Better heat dissipation for stable performance in aggressive machining
Reduced shank more flexible for deep workpiece

Usage Tips

CNC machines with rigid setups (avoid excessive runout)
Coolant: Can be used with or without coolant (AlTiN works well in dry conditions)
Suitable for: Steel (up to ~55 HRC), stainless steels, titanium, nickel alloys
