LMT Onsrud introduces a new cutting tool to machine composite materials. LMT Onsrud’s 66-700 series is designed to produce a superior edge in carbon fiber material, says the company.The tool’s low helix flute design results in reduced vibration and quiet cutting compared to PCD end mills, adds LMT Onsrud, and the open flute geometry allows for heat dissipation, which prevents resin flow.  The multi-flute configuration results in faster feed rates than a PCD tool, according to the company. LMT Onsrud’s 66-700 series, DFC Multi-Flute Low Helix Tools, are coated with a diamond film coating to extend tool life when used with highly abrasive composites, says the company.
