PRECORP INC was founded in 1986 to manufacture PCD drills using a new patented vein process. These drills found success in the aerospace industry drilling precision fastener holes in Carbon Fiber Reinforced Composites (CFRP). Over the years we have added new PCD cutting tools and entered new markets expanding our PCD tool offering to reamers, end mills, spot facers, milling and turning inserts, and countersink tools.
