ALUMINUM'S FASTEST, FINEST, FINISH
with Kyocera's Ultra Fine Pitch Cutters

The MD90 delivers high-speed aluminum finishing with exceptional surface quality. Its fine-pitch design with PCD inserts reduces burrs, resists chatter, and supports aggressive feed rates. Whether you're machining EV housings, aerospace panels, or battery trays, the MD90 is built to keep your cycle times low and your finish standards high.

MD90 Display

Surface Quality + Stability

High-speed aluminum machining often means burrs, chatter, and inconsistent finishes. The MD90 counters this with a fine-pitch, low-vibration design and PCD inserts that suppress burrs and deliver mirror-like finishes up to 0.18 μmRa even in long-reach setups.


Productivity + Tool Life

From abrasive aluminum alloys to uncontrolled chip flow, aluminum machining presents constant challenges. The MD90’s PCD inserts resist wear at over 9,800 sfm, while optimized chip flow and high flute count support 30–40% faster feeds without sacrificing finish or stability.

PREMIUM FINISH WITH HIGHER FEEDS

Get more done in less time. Capable of 945 ipm feed rates, the ultra-fine pitch design boosts efficiency while delivering precision finishes and long-lasting tool life in aluminum machining.
