65 Mold Steel Long Neck Corner Radius End Mill【2 Flutes Φ0.2-2】

Get 65 Mold Steel Long Neck Corner Radius End Mill with 2 Flutes at SAMHO

At SAMHO, we pride ourselves on offering high-quality tools for your machining needs and introducing our 65 Mold Steel Long Neck Corner Radius End Mill, featuring 2 flutes and a diameter range of Φ0.2-2. With its long neck design and corner radius feature, this end mill is perfect for precise and efficient cutting applications in the mold and die industry.

  1. Purpose-Built for Hardened Steels up to 65HRC – Combines Reach, Strength, and Surface Quality
    Crafted from ultra-fine grain carbide and designed for superior wear resistance, this tool is optimized for machining high-HRC mold steels and hardened components. The long neck structure allows for extended reach in deep or complex cavities, while the corner radius improves tool strength and edge durability.

  2. Corner Radius Design Reduces Edge Chipping and Enhances Tool Life
    Compared to sharp-edged tools, the reinforced corner radius minimizes stress concentration and delays edge breakage—especially important when machining hardened materials. It delivers longer tool life and consistent part quality over extended runs.

  3. 2-Flute Geometry Optimized for Chip Evacuation and Finishing Control
    With wide flutes and fewer edges, the 2-flute design improves chip removal, reduces cutting heat, and provides better control in tight-radius or fine-detail finishing applications. It’s particularly effective in high-precision mold core and cavity machining.

  4. Long Neck + Short Flute Ratio Ensures Stability in Deep Features
    Engineered with a balanced neck-to-flute ratio, the tool maintains high rigidity even during deep reach operations, reducing tool deflection and vibration. Ideal for mold inserts, narrow walls, and ribs requiring excellent dimensional control.

  5. High Red Hardness Coating Supports High-Speed and Dry Machining
    Applied with a thermal-resistant nano-coating (e.g., HG), the tool retains edge sharpness at elevated temperatures, enabling dry or MQL (Minimum Quantity Lubrication) machining—supporting both performance and sustainability goals.

  6. Cutting Parameters Provided – Reduce Setup Time, Improve Consistency
    Each tool includes tested cutting data optimized for hardened steels, covering speed, feed, and depth of cut. This helps operators shorten trial-and-error setup, stabilize the cutting process, and maximize overall machining efficiency.

Why Choose the SAMHO HRC65 2 Flute Long Neck Corner Radius End Mill?

Material and Coating System Engineered for HRC65 Hardened Steel

This is not a general-purpose tool. It is specifically designed as a long neck corner radius end mill for hardened steel applications up to HRC65.

It is optimized for high-hardness mold steels such as SKD11, H13, D2, and ASP23.

Key engineering features include:

  • Ultra-fine grain tungsten carbide substrate
    Improves fracture resistance and flexural strength under heavy cutting loads.
  • High-performance heat-resistant coating system
    Reduces thermal wear and prevents edge softening during high-speed machining.

In real production, hardened steel tools fail mainly due to chipping and thermal cracking, not gradual wear.
This HRC65 end mill is designed to control both failure modes.

Stable Machining Window for Real Production Conditions

The main advantage of this long neck corner radius end mill for hardened steel is its wide and stable machining window.

It performs reliably even under unstable shop-floor conditions.

  • Resistant to light vibration during cutting
  • Works well on medium-rigidity machine setups
  • Maintains stability under long tool overhang conditions
  • Suitable for continuous mold production environments

For global buyers, this means:
Lower trial-and-error cost, reduced scrap risk, and more consistent batch quality.

Excellent Surface Quality for Mold Finishing

This tool is optimized for finishing hardened steel mold cavities and complex 3D surfaces.

It provides:

  • Smooth and stable contour transitions
  • Reduced tool marks during finishing passes
  • Lower risk of “digging” or surface gouging
  • Less manual polishing after machining

In mold shops, this improves pre-polish surface quality and reduces downstream finishing time.

Improved Surface Consistency in Finishing and Semi-Finishing

In hardened steel machining, stability is more important than material removal rate.

This long neck corner radius end mill for hard steel delivers:

  • Reduced chatter marks on finished surfaces
  • Better dimensional consistency on 3D profiles
  • Lower risk of burr formation and overcutting
  • Improved repeatability in batch production

It is especially effective in electrode finishing and precision cavity machining.

Core Engineering Value for Global Buyers

The SAMHO HRC65 2-flute long-neck corner radius end mill provides a balanced solution for deep cavity and hardened steel machining.

Key advantages include:

  • Stable cutting performance in HRC48–62 hardened steels
  • Long-neck geometry for deep cavity and anti-interference machining
  • 2-flute design for improved chip evacuation and lower cutting heat
  • Corner radius edge for improved strength and reduced chipping risk
  • High reliability in complex mold geometries
  • Extended tool life with reduced risk of scrap and rework
