2-Flute Long-Neck Ball-End Diamond-Coated End Mill

Precision Tool for Machining Graphite & Ceramic Materials

Engineered for high-hardness, brittle non-metallic materials such as graphite and electrical ceramics, this 2-flute long-neck ball-end carbide end mill features a high-adhesion diamond coating. It offers outstanding wear resistance, thermal stability, and surface finish. Proven in real-world dry and MQL conditions, the tool consistently delivers a service life of over 18 hours, making it ideal for high-efficiency CNC machining applications.

High-Hardness Diamond Coating for Extended Tool Life
Utilizes a high-adhesion diamond coating with exceptional hardness and chemical stability. This layer effectively resists abrasive graphite dust and edge micro-chipping, ensuring long-lasting performance in dry machining environments.

Long-Neck Design for Deep Cavity and Complex Part Access
The extended neck geometry allows improved reach into deep cavities and narrow features while minimizing interference. Ideal for machining graphite molds, electrode undercuts, ceramic components, and other geometrically complex parts with high precision.

2-Flute Ball-Nose Geometry for 3D Contours & Smooth Finishes
Perfect for freeform surfaces, 3D cavities, and fillets, the ball-end profile supports continuous cutting with reduced tool marks. Delivers superior surface integrity, especially on curved or contoured features.

Ultrafine-Grain Carbide Substrate for Strength & Crack Resistance
Manufactured from premium ultrafine-grain carbide, the tool body combines high hardness with excellent resistance to thermal cracking—critical for machining abrasive and brittle materials like graphite and ceramics.

5-Axis CNC Precision Grinding with Tight Tolerances
Each tool is precision-ground using advanced 5-axis CNC grinding technology, with dimensional tolerances controlled to within ±0.01 mm. This ensures consistent performance in applications demanding tight geometric and positional accuracy, including graphite electrodes, ceramic molds, and microstructure components.

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

Premium Diamond Coating for Extended Tool Life

Graphite machining requires specialized protection. SAMHO utilizes industry-leading Nanodiamond coating technology, delivering extreme surface hardness and exceptional adhesion to the solid carbide substrate. This superior bond prevents delamination and micro-chipping. As a result, SAMHO tools last up to 10 times longer than uncoated tools, significantly lowering your cost-per-part.

Optimized 2-Flute Geometry for Dust Evacuation

Unlike metals, cutting graphite produces highly abrasive, fine dust instead of traditional chips. SAMHO’s engineered 2-flute configuration provides maximum chip pocket space. This geometry ensures rapid, smooth dust extraction during high-speed machining. By preventing dust re-cutting, it protects both the tool edge from premature wear and the workpiece from surface scratches.

Rigidity and Reach: Precision Long-Neck Design

Manufacturing deep-cavity molds or narrow slots for EDM electrodes requires specialized reach. SAMHO’s long-neck design extends your machining depth without sacrificing tool rigidity. The optimized neck taper prevents tool deflection and clearance interference. It is the perfect choice for high-precision finishing on complex 3D surfaces.

High-Precision Ball Nose Tolerances

The contour accuracy of your graphite electrode directly impacts the final molded part. SAMHO maintains extremely tight tolerances on the ball nose radius (R). This geometric precision ensures a flawless surface finish straight out of the CNC machine, eliminating hours of manual polishing and benchwork.

Data-Driven Engineering: Transparent Technical Data

We eliminate the guesswork for overseas manufacturing engineers. SAMHO provides clear, comprehensive Speed & Feed Calculators and cutting parameter charts. Accurate data for spindle speed, feed rate, and depth of cut (ap / ae) are readily available. This data-driven support shortens your trial-and-error period and ensures optimal performance on day one.

One-Stop Sourcing with Comprehensive Specifications

Every mold shop faces unique challenges, requiring diverse neck lengths, shank diameters, and micro-diameters. SAMHO offers an extensive product matrix to meet these demands. Whether you need a standard high-volume order or a small-batch custom tool, our flexible production line ensures rapid response and short lead times.

Top-Tier Performance with Competitive Global Cost

You don’t have to compromise between quality and cost. SAMHO matches the tool life and reliability of premium European and American brands, but at a much more competitive price point. Backed by a responsive global logistics network, SAMHO helps global buyers optimize their supply chain costs while upgrading their machining efficiency.
