Aerospace Industry



LMT Onsrud has created an extensive line of cutting tools designed for these difficult to machine, space age materials.

Composite Tooling

Using metal cutting tools to machine today's highly abrasive composite materials increases costs in terms of tool wear and damage to work pieces. LMT Onsrud has created an extensive line of cutting tools designed for these difficult to machine, space age materials. Our Solid Carbide and PCD cutting tools are designed specifically for machining Carbon Fiber Reinforced Plastic (CFRP), Glass Reinforced Plastic (GRP), Fiberglass, Phenolic, Kevlar, Carbon Graphite and other composite materials.


Composite Drills

Drilling holes in composite materials is just as important as machining. 60% of all rejected parts are due to hole imperfections due to delamination of the material caused by excessive pressure while drilling. Our many styles of solid carbide and PCD Drills ensure accuracy of the hold being drilled based on the material and application.



LMT Onsrud produces the industry's largest selection of cutting tools used to machine honeycomb core and sandwiched structured composite panels. These materials are strong, while being lightweight in construction and being used within the aerospace, marine, transportation and wind energy applications.

Exotic Metals Milling

LMT Onsrud's broad offering of high performance End Mills for Exotic Metals & Stainless Steels include TV series for versatility in slotting, roughing and semi-finishing. The TF Series for superior finishing. Maximize the output of your spindle while producing accurate and quality parts. Features such as variable flute indexing, rigid tool design, and built in dampening effects increase productivity. Largest selection of corner radii and neck and flute lengths!


Aluminum Milling/Aluminum Routing

Our aluminum tools are suitable for use in both low and high speed machining applications and when used at the proper settings, will reduced chatter increasing tool life, higher quality parts and optimizes cutting efficiencies. Lowest cost per part possible!


Our Aluminum Rougher series are designed for heavy metal removal rates and with a ground in chipbreaker and open flute geometry, one can slot 30% faster than our standard AF series tool. Coolant and non-coolant through tooling!
