4-Flute Long Neck Flat Diamond Coated End Mill

Specialized Tool for High-Efficiency Machining of Graphite and Ceramic Materials

Engineered specifically for high-hardness, brittle non-metallic materials such as graphite and electrical ceramics, this 4-flute long neck flat end mill features a high-performance diamond coating. With excellent wear resistance, tool rigidity, and dimensional stability, it’s ideal for dry cutting or MQL on CNC machining centers. Real-world testing shows tool life exceeding 18 hours under continuous operation.

High-Hardness Diamond Coating for Extended Tool Life
Utilizes a durable, high-adhesion diamond coating that delivers extreme surface hardness and chemical stability. It significantly reduces wear and edge chipping during dry machining of abrasive materials like graphite, while maintaining sharp cutting edges over prolonged use.

Extended Neck Design for Deep Cavities and Fine Features
The long neck geometry enhances reach and clearance, making it ideal for precision machining in deep cavities, narrow slots, and complex geometries—perfect for graphite electrodes and intricate ceramic components.

4-Flute Configuration Increases Rigidity and Cutting Efficiency
The multi-edge design improves tool rigidity and vibration control, enabling stable high-speed operations. It’s well-suited for side milling, face finishing, and contouring, delivering high-quality surface finishes with improved productivity.

Ultra-Fine Grain Carbide Substrate for Toughness and Stability
Crafted from premium micro-grain carbide, the tool offers exceptional resistance to thermal cracking and fracture, ensuring consistent performance when machining abrasive and brittle materials such as ceramics and graphite.

High-Precision CNC Grinding with ±0.01mm Tolerance
Manufactured using advanced 5-axis CNC grinding technology, the tool maintains tight dimensional tolerances, supporting critical applications in moldmaking, electrodes, and high-precision ceramic structures.

Why Global Buyers Choose SAMHO as Their Graphite End Mill Supplier？

Exceptional Wear Resistance: CVD Diamond Coating Tailored for Graphite

Graphite is highly abrasive. It causes rapid flank wear on cutting tools. Standard uncoated or TiAlN-coated tools wear out almost instantly when machining graphite.

  • The Technology: SAMHO’s 4-flute long-neck graphite end mills feature a high-density, high-adhesion Nano Diamond Coating. This premium coating delivers an ultra-high hardness of up to 10,000 HV and exceptional thermal conductivity.

  • The Buyer Benefit: SAMHO’s diamond tools last 8 to 10 times longer than standard tools. This drastic increase in tool life minimizes your machine downtime for tool changes and drastically lowers your cost-per-part.

Optimized Geometry: The Ideal 4-Flute & Long-Neck Combination

Machining graphite electrodes or 3D molds often requires milling deep cavities and narrow slots. Standard tool geometries simply cannot handle these geometries efficiently.

  • Long-Neck Clearance Design: We have optimized the neck length-to-diameter ratio. This engineering choice provides maximum clearance without sacrificing rigidity. The tool easily reaches the bottom of deep slots while preventing tool holder interference.

  • High-Efficiency 4-Flute Balance: Compared to 2-flute alternatives, our 4-flute design offers superior rigidity and a higher Material Removal Rate (MRR). In high-speed machining (HSM), 4 flutes allow for a finer feed-per-tooth. This eliminates edge chipping on the graphite and delivers a flawless surface finish.

Strict Dimensional Tolerance and Runout Control

High-end industries like automotive molding and semiconductor manufacturing demand extreme precision. Often, parts require a dimensional tolerance within 0 – 0.005 mm.

  • The Technology: SAMHO utilizes top-tier European 5-axis CNC grinding machines (such as Rollomatic and Walter) for edge grinding. We strictly control the radial runout to  ≤ 0.002 mm.

  • The Buyer Benefit: Ultra-low runout ensures perfectly even load distribution across all four cutting edges. This prevents premature wear on any single flute. For your workshop, this means guaranteed dimensional consistency during batch production. You will no longer need to make frequent tool compensation adjustments.

Robust Digital Support & Flexible OEM/ODM Supply Chain

In today’s digital procurement landscape, overseas buyers want more than just a product. They want trust, efficiency, and convenience.

  • Transparent Speeds & Feeds (Speed & Feed Calculator): The SAMHO website features a comprehensive E-Catalog and cutting parameter charts. Engineers can instantly access recommended cutting speeds (Vc) and feed per tooth (Fz) for various graphite grades. This eliminates trial-and-error costs at your factory.

  • Rapid Non-Standard Customization: Graphite parts often require custom corner-clearing or deep-cavity milling. Backed by a responsive supply chain, SAMHO can customize 4-flute long-neck tools based on your CAD drawings. We offer custom neck lengths and flute lengths with industry-leading turnaround times.
