PCD cutting tools


5 times more productive
Whether drilling into precast holes or solid, KYOCERA UNIMERCO's family of PCD reamers can achieve more than 5 times the feed rate of traditional padded, adjustable PCD reamers. 

Lower total cost
Choosing a PCD tool solution is often the best way to reduce the cost per part. PCD tools offer a number of advantages: 

  • longer tool life
  • higher workpiece quality
  • better process reliability
  • reduced rejection

The result is lower machining costs and thus the lowest unit price.
