Carbide Micro End Mill

Micro-machining requires uncompromising accuracy and exceptional tool stability. Sundi’s solid carbide micro end mills are engineered for the most demanding miniature applications, featuring cutting diameters starting from an ultra-fine 0.2mm. Manufactured from premium sub-micron grain tungsten carbide, these miniature cutters deliver extraordinary rigidity, minimizing tool deflection and preventing breakage during high-speed, tight-tolerance milling operations.

Key Applications for Micro End Mills

Medical Device Manufacturing: Ideal for machining intricate features on surgical instruments, orthopedic implants, and dental components using challenging, biocompatible materials like titanium and stainless steel.
Micro-Mold & Die Making: The ultimate solution for executing fine details, microscopic ribs, and complex micro-cavities in hardened tool steels with extreme dimensional accuracy.
Electronics & Semiconductors: Optimized for high-speed routing, precise slotting of miniaturized electronic components, PCBs, and complex copper electrodes (EDM).
Aerospace & Watchmaking: Delivering sub-micron surface finishes for micro-mechanical parts, watch gears, and micro-fluidic channels where absolute precision is non-negotiable.

Advantages of Sundi Micro End Mills

Strict TIR Control & Anti-Breakage Design

At the micro-scale, runout is the enemy. Our micro end mills are ground with strict Total Indicator Reading (TIR) control and optimized core diameters, drastically reducing vibrations and preventing premature tool breakage.

Ultra-Fine Grain Carbide Substrate

Utilizing extremely pure, ultra-fine grain tungsten carbide rods to ensure the cutting edges remain razor-sharp and intact, even when machining challenging alloys at micro-diameters.

Optimized Nano-Coating Technology

Featuring advanced, ultra-thin PVD coatings (such as Blue Nano or TiSiN) that provide superior heat resistance and lubricity without blunting the microscopic cutting edges, ensuring smooth chip evacuation.

0.2mm Capability & Custom B2B Solutions

Ground on world-class 5-axis CNC machines, we reliably manufacture tool diameters down to 0.2mm. As a direct factory, we also offer custom neck lengths, clearance angles, and specific geometries to match your exact blueprints.
