ECI-H4/5R-CF Variable Helix and CHATTERFREE Endmills

Product catalog summary

New Product Announcement
ISCAR introduces the ECI-H4/5R-CF series of CHATTERFREE solid carbide endmills, designed for improved performance in roughing and finishing operations. These endmills feature variable pitch and different helix angles to enhance chatter dampening.

Product Specifications

ECI-H4R-CF Endmills: 4-flute design with variable pitch and helix angles of 35° and 37°. Available in cylindrical and relieved shank versions, with diameters ranging from 0.250 to 1.000 inches.
ECI-H5M-CFR Endmills: 5-flute design with helix angles of 36°, 37°, and 38°. Available in diameters from 0.250 to 0.750 inches.
All endmills are made from IC900, a versatile PVD coated grade, and include cylindrical and Weldon shank options.

Performance and Benefits
The new endmills offer improved dampening, resulting in a 20-25% increase in tool life. They reduce cutting forces and power consumption, enhance chip evacuation, and provide better surface quality on stainless and alloyed steel. These tools are particularly beneficial for low power machines with CAT40 or BT40 adaptations.

Recommended Machining Data
Detailed specifications for each endmill variant are provided, including dimensions, recommended feed rates, and machining parameters.

Test Report Summary
Field tests demonstrate the superior performance of the new endmills compared to standard CHATTERFREE models. Notable improvements include increased tool life and reduced wear during shoulder milling applications on materials such as AISI 4340 and AISI 304L.

Highlights ISCAR is introducing a new evolution of the CHATTERFREE solid carbide endmills with variable pitch and different flute helix angles for roughing and finishing operations. The new ECI-H4R-CF endmills feature a 4 flute, variable pitch (similar to the standard CHATTERFREE endmills) and in addition different helix flute angles: two 35° and two 37° helix flutes. Two 4-flute families are available: cylindrical and relieved shank endmills. The cylindrical family includes endmills in a diameter range of .250 to 1.000” and the relieved shank family includes endmills in a diameter range of .250...
