The iEcho ER series tungsten carbide end mills are carbide end mills specifically designed for high-precision industrial CNC cutting machines (such as the iEcho RZ series high-speed, high-power CNC end mill spindle systems). These tools are primarily used for cutting high-hardness or composite materials such as acrylic, aluminum sheets, MDF, rigid foam, polycarbonate, plastics, and wood.

To facilitate your production procurement and equipment parameter matching, the following is a summary of the specifications, design classifications, and operating process suggestions for the core models in this series:

Core Model and Geometric Structure Analysis

Different part numbers represent different cutting diameters , shank diameters , cutting lengths , and flute designs for the cutting tools. Common standard model parameter patterns are as follows:

iEcho ER64.2:
- Specifications : Typically has a shank diameter of 6mm and a cutting diameter of 4mm , with a maximum cutting depth (cutting length) of approximately 22mm .
- Structure : Featuring a double-edge up-cut design, it improves cutting efficiency while ensuring extremely high surface finish, making it ideal for precision machining of plastics and wood.
iEcho ER64.3:
- Specifications : It has a shank diameter of 6mm and a cutting diameter of 4mm , with a maximum cutting depth of approximately 14mm .
- Structure : Featuring a **Single-edge Up-cut** design, suitable for high-temperature, high-speed environments. The single-edge design provides a larger chip groove, significantly reducing heat buildup and preventing materials such as acrylic from melting and sticking to the tool during high-speed machining.
ER62.1A / ER63.1A / ER65.1A / ER66.1A / ER66.3A series :
- Models with the "A" suffix are typically dynamically balanced specifically for iEcho's 1.0KW or 1.8KW high-frequency spindle (Milling Spindle).
- ER62 / ER63 are typically used for micro-machining with smaller cutting diameters (such as 2mm - 3mm), for fine engraving or small radius corner clearing.
- The ER66 series (such as ER66.1A and ER66.3A) typically corresponds to a larger depth of cut or a larger cutting diameter (such as 6mm cutting diameter), and is often used for rapid roughing and cutting of thick plates.

Key technological advantages

100% Premium Solid Tungsten Carbide : Made by hot pressing and sintering high-purity tungsten steel and cobalt powder, it possesses extremely high red hardness (high temperature resistance) and wear resistance. Even when the spindle generates high heat through high-speed friction, the cutting edge remains sharp for a long time.
Single/double-edge up-cut spiral design : The spiral groove can force the chips to be discharged upward along the tool axis, avoiding secondary cutting or jamming of chips in the machining area, fundamentally reducing burrs on the workpiece edge and greatly extending tool life.
Vibration-resistant large core diameter design : The high-precision cutting edge combined with a reasonable negative rake angle enhances the rigidity of the tool body, effectively suppressing vibration at extremely high speeds of up to 60,000 RPM, ensuring that the cutting edge is vertical and does not tilt.
