tool life in carbon fiber
Delamination, uncut fibers, and fiber pull-out are what make composites brutal to machine. RobbJack's polycrystalline-diamond (PCD) tools are engineered for exactly that fight — a sharp diamond edge that shears the fiber cleanly instead of tearing it.
From the 135°/20° 8-facet Single Shot drill that drills and reams in one operation to single-pass CFRP trimming routers, PCD turns the worst operations on the line into the most predictable.
Why it wins
- Solid-diamond edges that shear fiber cleanly — no delamination or pull-out.
- Single Shot drills drill and ream in one operation.
- Single-pass CFRP trimming routers replace rough-plus-finish processes.
- Re-sharpenable for even longer service life.
- PCD form tools, tipped slitting saws, and hole saws available.
