Highlights


The new ECP-H7-CF family features 3xD, 4xD and 6xD cutting length to diameter ratios for 6 to 16 mm diameter tools and 3xD and 4xD for 20 mm diameter tools. The new chip-splitting solid carbide endmills are intended for rough to semi finish machining at high cutting speed and can also be applied to high speed milling (HSM) operations. ECP-H7-CF endmills provide an improved performance and higher versatility than the tools available up till now, which possess cutting edges without chip-splitting grooves, particularly at high overhang.

Designation key code



Features

• 7 flute different helix and variable pitch solid carbide endmills with chip-splitting geometry for rough to semi-finish operations as well as HSM by trochoidal method
• Unique design of chip-splitting grooves on the cutting edge provides satisfactory surface finish for most requirements
• Enlarged chip flute for effective chip evacuation
• Produced from IC902, an ultra-fine carbide grade with TiAlN PVD coating providing excellent performance in machining various materials, especially, hard steel and cast iron.
• h6 shank tolerance

Advantages

• Very high productivity on most material types
• Excellent chip evacuation
• Low cutting forces
• Designed mainly for rough to semi-finish operations, it also provides a satisfactory surface finish even at maximum ap
• High performance in a wide range of machining speeds
• Optimal flute design delivering maximum metal removal rates

Application Instructions
Endmill that is longer than necessary is less rigid and requires reducing the cutting conditions.
The new cutting length options with chip-splitting provide an optimal tool for very high-speed machining and enable machining even under less favorable conditions.

Width of cut (ae) should be set depending on the cutting length:

• For endmills with 3xD cutting length - up to 0.3xD max. according to system stability
• For endmills with 4xD cutting length - up to 0.25xD max. according to system stability
• For endmills with 6xD cutting length - up to 0.1xD max. according to system stability

Cutting data
The attached table provides estimated starting cutting data. For machining in unstable conditions, the table data should be reduced by 20-30%.
