Product Description

Product Description:

Chamfer end mills are commonly used for various applications, such as deburring, edge breaking, and chamfering. They are particularly useful for creating chamfers on holes or slots, where a countersink or chamfered edge is desired.

When selecting a chamfer end mill for CNC machining, there are a few factors to consider:

  • Material: Choose an end mill that is suitable for the material you are working with. Different materials require different cutting tool geometries and coatings for optimal performance.
  • Angle: Chamfer end mills come in various angles, such as 45 degrees, 60 degrees, or custom angles. The angle determines the width and depth of the chamfered edge.
  • Diameter: Consider the size of the chamfer you want to create and choose an end mill with an appropriate diameter. Smaller diameters are suitable for finer chamfers, while larger diameters are used for more substantial chamfers.
  • Flute Count: The number of flutes on the end mill affects chip evacuation and surface finish. Higher flute counts can provide better performance in certain applications.
  • Coating: Coatings, such as TiN (Titanium Nitride) or TiAlN (Titanium Aluminum Nitride), can enhance the tool's durability, reduce friction, and improve chip evacuation.


Carbide chamfer end mills have several features that make them well-suited for machining applications. Here are some notable features of carbide chamfer end mills:
  • Material Composition: Carbide chamfer end mills are typically made from solid carbide, which is a composite material consisting of tungsten carbide particles bonded together with a cobalt or nickel binder. Carbide is known for its exceptional hardness, wear resistance, and heat resistance, making it suitable for demanding machining operations.
  • Hardness and Wear Resistance: Carbide chamfer end mills offer high hardness, allowing them to maintain their cutting edge sharpness for extended periods. This hardness enables them to withstand the high cutting forces encountered during machining and resist wear, resulting in longer tool life compared to other materials.
  • Heat Resistance: Carbide has excellent heat resistance, enabling carbide chamfer end mills to withstand high cutting temperatures without significant deformation or loss of hardness. This heat resistance is particularly important when machining materials that generate high heat, such as stainless steel or titanium.
  • Cutting Edge Geometry: Carbide chamfer end mills can be manufactured with various cutting edge geometries, including single-flute, two-flute, or multiple-flute designs. The specific geometry impacts factors such as chip evacuation, cutting stability, and surface finish. Manufacturers offer a range of options to suit different machining requirements.
  • Coating Options: Carbide chamfer end mills may be available with various coatings to further enhance their performance. Common coatings include TiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), and AlTiN (Aluminum Titanium Nitride). These coatings can provide additional benefits such as increased hardness, improved lubricity, reduced friction, and enhanced chip evacuation.
  • Precision and Accuracy: Carbide chamfer end mills are manufactured with high precision and tight tolerances, ensuring consistent performance and accurate results. This precision is crucial for achieving precise chamfers and maintaining dimensional accuracy in the machined workpiece.

Overall, carbide chamfer end mills offer excellent hardness, wear resistance, heat resistance, and precision, making them a reliable choice for a wide range of machining applications. Their durability and performance make them well-suited for demanding materials and machining operations, improving productivity and reducing tooling costs in the long run.


Technical Parameters:

When using chamfer end mills, several important cutting parameters should be considered to achieve optimal results. Here are some key parameters to keep in mind:

Feed Rate: The feed rate refers to the speed at which the cutting tool advances into the workpiece. It is typically measured in distance per revolution (inches per minute or millimeters per minute). A proper feed rate ensures efficient material removal and helps prevent tool wear. Adjust the feed rate based on the material being machined, the tool diameter, and the machine's capabilities.

Cutting Speed: The cutting speed is the relative surface speed between the cutting tool and the workpiece. It is typically measured in surface feet per minute (SFPM) or meters per minute (m/min). The cutting speed is influenced by the material being machined and the tool material. Consult cutting speed recommendations provided by the tool manufacturer or refer to machining handbooks for appropriate cutting speed ranges.

Depth of Cut: The depth of cut is the distance between the original surface of the workpiece and the final machined surface. It determines how much material is removed during each pass. It's important to consider the tool's diameter and the desired chamfer width when determining the appropriate depth of cut. Avoid excessive depths of cut that can overload the tool or machine, leading to poor surface finish or tool breakage.

Stepover: The stepover, also known as radial depth of cut or scallop height, is the distance between each pass of the tool. It determines the width of the tool path and affects the surface finish. A smaller stepover provides a finer finish but may require more passes, while a larger stepover can remove material more quickly but may result in a rougher surface. Experiment with different stepover values to find the optimal balance between productivity and finish quality.

Coolant/Lubrication: Depending on the material being machined, using coolant or lubrication can help dissipate heat, reduce friction and chip welding, and prolong tool life. Some materials, like aluminum, benefit from the use of coolant to prevent chip buildup and improve surface finish. Refer to the manufacturer's recommendations or machining guidelines for specific coolant/lubrication requirements.

Tool Path Strategy: The choice of tool path strategy can also impact the performance of chamfer end mills. Common strategies include conventional milling (climb milling), where the tool rotates against the feed direction, and climb milling, where the tool rotates in the same direction as the feed. Each strategy has its advantages and considerations, such as tool deflection, surface finish, and chip evacuation. Evaluate each strategy to determine which is best for your application.



Chamfer end mills are widely employed for machining materials ranging from metals to ceramics. Metals like aluminum, steel, stainless steel, brass, and copper can all benefit from the use of these milling tools for chamfers on edges, countersinking holes, and removing burrs. Plastics like acrylic, polycarbonate, nylon, and ABS can produce clean chamfered edges without causing melting or chipping. Woodworking applications like creating chamfers and beveled edges on wooden pieces work best with chamfer end mills and can be used on both softwoods and hardwoods. Even composite materials such as fiberglass-reinforced plastics (FRP) and carbon fiber composites can be suitably machined with the use of the appropriate tools, to prevent delamination and precise chamfers.

When selecting the ideal chamfer end mill and different cutting parameters to use, it is important to consider the material properties such as hardness, brittleness, and thermal conductivity. This will help to ensure optimal machining performance and extended tool life.
