EC-H5M-CFR Variable 5 Helix and CHATTERFREE Endmills

Product catalog summary

New Product Announcement: EC-H5M-CFR Endmills

Introduction: ISCAR has introduced a new line of CHATTERFREE solid carbide endmills, the EC-H5M-CFR, designed for both roughing and finishing operations. These endmills feature a variable pitch and five different flute helix angles, enhancing dampening performance and extending tool life by 20 to 25% compared to standard models.

Specifications: The EC-H5M-CFR endmills come with 5 flutes and variable pitch, available in helix angles of 36°, 37°, and 38°. They are offered in cylindrical and Weldon shank designs, made from the versatile IC900 PVD coated grade. The diameter range is from 4 to 20 mm, all with corner radii.

Performance and Benefits: These endmills reduce cutting forces and power consumption, improve tool life, and provide better chip evacuation and surface quality on stainless and alloyed steel. They are particularly beneficial for low power machines with ISO40 or BT40 adaptations, enhancing material removal rates and minimizing vibration. They support full slot machining up to 1.5XD.

Dimensions and Machining Data: The document provides detailed dimensions and recommended machining data for various endmill models, including diameter, shank type, and feed rates.

Test Report: A test conducted on AISI 316L material for shoulder milling showed that the EC-H5M-CFR endmills achieved a tool life of 97 minutes compared to 75 minutes for the previous model, with similar wear rates.
