End mill for hardened steel

Dohre's End Mills for Hardened Steel

As a trusted carbide end mill manufacturer in China, Dohre’s specializes in producing cutting tools that deliver outstanding performance when machining hardened steel.
Our end mills are engineered to maintain sharpness, precision, and stability even under extreme hardness and high-temperature conditions — ensuring excellent productivity and long tool life for mold, die, and tooling industries.

Why Hardened Steel Requires Specialized End Mills

Hardened steel (typically above 50 HRC) presents significant challenges in machining due to its high hardness, low machinability, and strong abrasive properties.
Standard tools tend to wear quickly or lose cutting edge integrity, resulting in poor surface finish and dimensional inaccuracies.

Dohre’s end mills for hardened steel are built with ultra-fine tungsten carbide substrates and advanced TiSiN or AlTiN coatings to resist wear, oxidation, and thermal deformation.
They are ideal for dry or semi-dry machining of materials up to 65 HRC, providing consistent results and superior efficiency.

Key Features of Dohre’s Hardened Steel End Mills

High-Hardness Carbide Substrate: Ensures rigidity and durability during high-load cutting.
TiSiN / AlTiN Coating: Provides exceptional heat resistance and anti-oxidation properties.
Optimized Flute Design: Reduces cutting force and enhances chip evacuation.
Sharp & Stable Cutting Edge: Prevents chipping and maintains accuracy under high pressure.
Precision Grinding: Manufactured on 5-axis CNC machines to ensure geometric consistency.

Each Dohre’s carbide end mill undergoes strict quality inspection to guarantee high precision and reliability in hardened material cutting.

Material Excellence

We strictly select 100% virgin tungsten carbide as the raw material for all our milling tools. Compared to recycled powders, virgin carbide offers significantly better hardness, toughness, and stability. This ensures excellent wear resistance, consistent quality, and longer tool life, even in high-speed or high-hardness machining environments.
Advanced Imported Equipment

Our production line features state-of-the-art CNC grinding machines imported from Germany, Koera, including brands like WALTER, ANCA, and DECKEL. These high-precision machines enable us to achieve superior tool geometry, tight tolerances, and stable quality in mass production to meeting the demands of even the most challenging machining applications.
In-House Coating Equipment

Our factory is equipped with advanced PVD and CVD coating systems, allowing us to apply and control various high-performance coatings such as AlTiN, TiSiN, and nano-layer coatings. With full in-house capability, we can optimize coatings based on different materials—whether for steel, aluminum, or hardened alloys, ensuring better heat resistance, smoother chip flow, and extended tool performance.
Strict Quality Control

Every tool goes through multiple quality inspection stages, from raw material testing and in-process checks to final dimensional and coating inspections. Our comprehensive QC system ensures that only fully qualified products leave the factory.
