LMT Onsrud

LMT Onsrud manufactures its cutting tools in the USA, supplying solid carbide end mills and router bits for CNC routing and milling. This line is built around aerospace, composites, plastics, woodworking, and metalworking applications, where consistent geometry and tight tolerances matter as much as raw cutting speed.


For composite and wood-composite work, Onsrud's compression-style bits cut from both directions at once: the upward-spiraling lower flutes and downward-spiraling upper flutes press fibers inward from the top and bottom surfaces simultaneously, which is what keeps edges clean and chip-free on materials that would otherwise tear out under a standard up-cut or down-cut bit.


Because the tooling is engineered for high-speed production environments, it's a common choice in shops running long unattended cycles, where tool life and predictable wear matter as much as any single cut. It covers everyday routing and milling work just as well as specialty production runs.
