Composite Tools Aerospace and Medical Industry

Using metal cutting tools to machine today’s highly abrasive composite materials can be costly in terms of tool wear and damage to workpieces. LMT Onsrud makes an extensive line of cutting tools designed for today’s difficult-to-machine, space-age materials. LMT Onsrud manufactures solid carbide and PCD cutting tools designed specifically for machining CFRP (Carbon Fiber Reinforced Plastic), GRP (Glass Reinforced Plastic), Fiberglass, Phenolic, Kevlar®, Carbon Graphite and other composite materials.
