New Solid Carbide 7 Flute CHATTERFREE Endmills with Chip-Splitting Cutting Edge
ISCAR is expanding the SOLIDMILL line of 7-flute CHATTERFREE solid carbide endmills by adding tools with chip-splitting cutting edges.
The new ECP-H7-CF family features 4xD and 6xD cutting length to diameter ratios for
.25” to .625” diameter tools and 4xD for .750” 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 already available tools,
which have a cutting edges without chip-spiltting groves tools especialy at high tool overhang.

Main Product 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 for machining
h6 shank tolerance
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

When using an endmill that is longer than necessary, it 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 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
The attached table provides estimated starting cutting data. For machining in unstable conditions,
the table data should be reduced by 20-30%.
