Product Description

Product Description:

Our Micro End Mills are specially designed for precise and accurate machining of brass, gold, and other metals. With a cutting diameter from 0.2-0.9mm and 2 flutes, these tools provide a high level of accuracy and precision. The square or ball nose cutting edge type ensures a smooth and efficient cut, while the 1/4" solid micro carbide 4 flute carbide end mill provides a durable finish. With a number of teeth of 2, this micro diameter end mill is perfect for intricate cutting and milling operations. With its superior cutting performance, our micro square end mill makes sure you get the best results every time you use it.



Carbide micro diameter end mills offer various advantages when compared to other types of end mills. They provide high precision and accuracy due to their small diameter, which is ideal for producing fine details and tight tolerances. Additionally, they are highly rigid and durable, providing excellent wear resistance that prolongs tool life. Furthermore, carbide end mills have exceptional heat resistance, making them suitable for high-speed machining operations. Their versatility enables them to machine a broad range of materials, with varying hardness levels. Moreover, they generate lower cutting forces, reducing machining stress, part deformation, and machine tool instability. However, these end mills are not suitable for general-purpose machining or roughing operations.

Adjusting Cutting Parameters


When using carbide micro diameter end mills, adjusting cutting parameters is essential to optimize machining performance for different materials. Here are some key cutting parameters to consider for machining specific materials:


Feed Rate: Generally, a higher feed rate can be used for softer metals like aluminum, while a lower feed rate is suitable for harder metals like stainless steel or titanium. Spindle Speed: Higher spindle speeds are typically employed for softer metals to increase material removal rates, while lower spindle speeds may be used for harder metals to reduce tool wear and heat generation.Depth of Cut: The depth of cut depends on the specific application and the stability of the machining setup. It is important to balance material removal rates with tool life and avoid excessive cutting forces.


Feed Rate: Plastics can be machined at relatively higher feed rates compared to metals. However, the feed rate should be adjusted based on the specific plastic material and its characteristics, such as hardness and heat sensitivity. Spindle Speed: Spindle speeds for machining plastics are typically moderate to high to prevent melting or excessive heat buildup. It is important to avoid excessive heat that can lead to material deformation or poor surface finish. Depth of Cut: Similar to metals, the depth of cut in plastics should be chosen carefully to balance material removal rates and prevent excessive cutting forces that might cause workpiece deformation or tool breakage.


Feed Rate: Composites like CFRP and FRP have unique machining properties. A lower feed rate is often recommended to prevent delamination or fiber pull-out during machining. Spindle Speed: Moderate to high spindle speeds are generally used for composites to maintain cutting efficiency and prevent excessive heat buildup. Depth of Cut: Composites are often machined with shallow depths of cut to minimize the risk of delamination and fiber damage. Multiple passes with increasing depth may be employed for roughing operations.


Feed Rate: Ceramics require lower feed rates compared to metals or plastics due to their high hardness and brittleness. Slow and controlled feed rates are necessary to prevent tool fracture and chipping. Spindle Speed: Moderate spindle speeds are typically used for ceramic machining. Excessive speeds can lead to tool wear or thermal damage, while too low speeds might result in poor surface finish. Depth of Cut: Ceramics are typically machined with shallow depths of cut due to their hardness. Multiple passes and proper cooling or lubrication methods are employed to dissipate heat generated during machining.

These parameters serve as general guidelines, and it's important to consider the specific material properties, machine capabilities, and desired machining outcomes. It's recommended to start with conservative cutting parameters and make adjustments based on the actual cutting performance and results achieved.



Carbide micro diameter end mills are capable of effectively machining a variety of materials, including:

Metals: Carbide micro diameter end mills can machine various metals, such as aluminum, stainless steel, tool steel, brass, copper, and titanium. They are well-suited for creating intricate features and precise cuts in these materials.

Plastics: End mills with small diameters are commonly used for machining plastics, including acrylic, polycarbonate, PVC, nylon, and ABS. The sharp cutting edges of carbide micro diameter end mills help produce clean cuts and smooth finishes in plastic components.

Composites: Carbide micro diameter end mills are suitable for machining composite materials, such as carbon fiber reinforced polymers (CFRP) and fiberglass reinforced polymers (FRP). These materials are commonly found in aerospace, automotive, and sporting goods industries.

Ceramics: While ceramics can be challenging to machine due to their hardness and brittleness, carbide micro diameter end mills can be used for machining certain ceramics like alumina and zirconia. Machining ceramics requires careful considerations in terms of tool selection, cutting parameters, and coolant/lubrication methods.

Printed Circuit Boards (PCBs): Carbide micro diameter end mills are extensively used in the electronics industry for machining PCBs. They can accurately mill traces, drill holes, and create fine features on the PCB surface.

It's important to consider the specific properties of each material and adjust cutting parameters accordingly when using carbide micro diameter end mills. Additionally, different coatings or geometries may be employed on the end mills to enhance performance and improve tool life when machining specific materials.
