PVD-Coated Milling Inserts Increase Production Efficiency With Less Downtime

Kyocera Precision Tools introduces the PR18 Series, a lineup of indexable milling inserts meticulously crafted to elevate the mold and die machining experience, amongst other machining applications, across Kyocera’s most popular milling lines. At the core of this series is the company’s new PVD coating technology, designed to eliminate frequent tool replacements and costly downtime. Each insert features multiple cutting edges.

The PR18 Series incorporates a proprietary Megacoat Nano Ex coating. The double lamination technique with two nanolayers for abrasion, wear and heat resistance is optimal for durability and high performance. Moreover, improved oxidation resistance and coating toughness suppresses crack growth and remains tougher longer, according to Kyocera. This results in prolonged tool life, reducing the need for frequent tool changes in the middle of production runs. Milling operations also maintain their precision and surface finish.

PR18 grades are available across more than 16 milling series cutter lines. The PR1825 is recommended for steel (wear resistance oriented), the PR1835 for stainless steel and and steel (stability oriented) and the PR1810 for cast iron. A compatible cutter series include various milling operations (facing, slotting, ramping, helical milling, shouldering, etc.) .
