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.

The LMT Onsrud 66-900 Series burr point composite router pairs multi-flute ESG-coated geometry with a burr-style tip that bites into slick, hard laminate surfaces — the answer when standard tips skate or wander on glossy fiberglass, carbon fiber, and dense composite plastic.

Why choose the burr-point geometry

  • Burr point tip grips hard, polished laminate faces on entry — no skating, no scrapped panels.
  • ESG coating stands up to the abrasive fillers that rapidly dull uncoated tooling.
  • Multi-flute geometry reduces vibration and heat for tight-tolerance profiles and clean edges.
  • Proven in hand-fed trim work and CNC nesting for marine, aerospace, and industrial composite fabrication.

Available part numbers

Imperial: 66-902ALTIN (1/8"), 66-906ALTIN (3/16"), 66-910ALTIN, 66-914ALTIN and 66-918ALTIN (1/4"), plus 3/8" and 1/2" sizes. Metric shanks 6 mm through 12 mm. Choose your cutting edge diameter, length, and shank from the options above.

Starting cuts with a plunge? Use the 66-900 drill point. For pure edge trimming and the finest profile finish, the 66-900 no-point version is the pick.
