“These 1/4” carbide burrs work so well with all the various composite materials we deal with. They leave a great finish and when boring holes and cavities, produce little to no chipping of surface finishes.”

- M. Masterson - Composite materials expert



They show little to no wear in regular use on composites. Great for use on fiberglass or carbon fibre aircraft or race car bodies.

High Performance:

Good for use in 1/4” (6mm) drills and die grinders. They are strong and aggressive, won’t fracture, shatter or bend and the grit won’t tear loose. They just get the job done - over and over again
