• Boring
  We specialize in long deep hole boring services. We bore up to 70′ lengths to improve straightness, wall thickness, surface finish or to facilitate balancing. Be sure to ask about our Large Honing facilities and Trepanning.
• Drilling
  Drilling provides a given hole size with a single machining pass. It may be through the part, or partially through (blind). We provide drilling services for holes ranging from 1.375″ to 8.25″ diameter. Grand Valley can machine your flat bottom or radiused blind holes as well.
