About this series
CPCD-203 PCD-Tipped Composite Routers
The best trimming tool for composites.
The CPCD-203 is a 2-flute PCD-tipped router with a 118 degree drill point for trimming composites. It plunges into the part without blowing out the back side, and produces no delamination, no uncut fibers, and no fiber pull-out. The tool can be re-sharpened and has demonstrated over 13,000 linear inches in aircraft CFRP material. A new PCD grade and geometries are specifically designed for CFRP materials.

Recommendations are computed starting points based on typical conditions — not guarantees of performance, tool life, or fitness for your application. Machining involves inherent risk: you are solely responsible for safe operation, for verifying every parameter against your machine, spindle, toolholding, workholding, and guarding limits, and for proving all parameters on a test cut before production. RobbJack Corporation assumes no liability for tool breakage, machine damage, scrapped parts, production loss, or personal injury arising from use of these recommendations.
