OSG USA Inc. offers the EXOPRO AERO-D-REAM drill/reamer for cutting carbon and glass-fiber composites. The tool has a tapered 4-flute design to limit peel-up at the hole entrance and an elongated, double-angle geometry to reduce thrust and limit exit delamination. Compared to its uncoated counterpart, the standard diamond-coated tool drilled 14 times the number of holes and provided better hole quality, according to company tests. The diamond-coated tool did not exhibit margin wear after 180 holes.
