Accusize Launches M42 Cobalt End Mill for Alloy Steel Machining

2026-01-06

Imagine facing a challenging alloy steel machining task that demands both high efficiency and extended tool life. Conventional end mills wear out quickly, requiring frequent replacements that significantly impact productivity. A specialized milling cutter emerges as the solution to this industrial challenge.

Product Overview

This high-performance roughing end mill is engineered for demanding machining operations. Combining premium materials, advanced coating technology, and optimized geometry, it delivers exceptional durability, thermal stability, and cutting efficiency. The tool excels when machining difficult materials like alloy steels and stainless steels, offering potential productivity gains while reducing tooling costs.

Key Advantages

The milling cutter's superior performance stems from several critical features:

Advanced Material Composition: Constructed from M42 high-speed steel with 8% cobalt content, the tool demonstrates enhanced hardness, wear resistance, and heat resistance. This composition maintains cutting performance at elevated temperatures, resisting softening and wear better than standard high-speed steel tools.
Cutting-Edge Coating: The TiAlN (titanium aluminum nitride) coating provides exceptional hardness and thermal stability. This surface treatment reduces friction during cutting operations, minimizing heat generation while protecting against wear and thermal deformation. The coating also enhances chemical stability, preventing adverse reactions between tool and workpiece materials.
Precision Engineering: The five-flute design balances cutting efficiency with reduced cutting forces and vibration. Multiple cutting edges enable higher metal removal rates, while the fine-tooth configuration improves surface finish, potentially reducing secondary finishing operations. With a 2-inch cutting length and 4.5-inch overall length, the tool offers versatile machining capabilities.
Dimensional Precision: The 1-inch diameter and matching shank diameter ensure stable mounting and reliable operation. The robust shank design withstands significant cutting forces while minimizing vibration for improved machining accuracy.

Technical Specifications

The milling cutter's performance characteristics are defined by these precise specifications:

Coating: TiAlN (titanium aluminum nitride)
Material: M42 high-speed steel with 8% cobalt
Diameter: 1 inch
Shank Diameter: 1 inch
Cutting Length: 2 inches
Overall Length: 4.5 inches
Number of Flutes: 5
Tooth Type: Fine

Industrial Applications

This milling solution proves particularly effective in several machining scenarios:

Alloy Steel Machining: Performs well with various alloy steels including tool steels, die steels, and bearing steels, overcoming the machining challenges posed by these hard materials.
Stainless Steel Processing: Effectively machines austenitic stainless steels (304, 316 series) while resisting built-up edge formation that can compromise surface quality.
Heavy-Duty Machining: Suitable for high-volume material removal and roughing operations where cutting performance and stability are paramount.
Production Environments: Offers economic advantages in batch production settings through extended tool life and reduced changeover frequency.

Conclusion

This specialized milling cutter represents a robust solution for challenging machining applications. Its combination of premium materials, advanced coating technology, and precision engineering addresses the demanding requirements of alloy steel and stainless steel machining. For manufacturing operations facing productivity challenges with difficult-to-machine materials, this tool offers a potential path to improved efficiency and reduced tooling expenses.
