The Ultra Marathon Compression is the newest addition to the LMT Onsrud compression offering and the next generation of the tools currently served by the Marathon series. An optimised cutting geometry is paired with a newly formulated Ultra Marathon coating that protects the cutting edge and extends tool life in panel materials.
Ultra Marathon coating
- Nanocomposite layer structure for enhanced wear resistance through hardness, helping the cutting edge stay effective longer.
- High surface quality — the coating carries the precision of the underlying grind through to the finished surface.
- Distinct copper / rose-gold appearance for immediate visual identification of a UMC tool on the shop floor.
Features and benefits
- All-new geometry engineered specifically for melamine, MDF, laminate and plywood.
- Three-flute geometry for higher-feed production running.
- A more precise, consistent cutting edge helps minimise chipping and produce better-quality finished parts.
- Compression geometry shears up on the lower flute and down on the upper flute, sealing both faces of a laminated panel.
Applications
Slotting, pocketing, profiling and high material removal in melamine laminated particleboard, melamine laminated MDF, plywood and MDF.
