About LMT Tools
LMT Tools is a specialized manufacturer of precision tools for turning processes. The company consolidates the expertise of the brands LMT Fette (Schwarzenbek), LMT Kieninger (Lahr), and LMT Onsrud (Waukegan, USA), manufacturing turning cutters, roller heads, special tool systems for cavity and mold construction, carbide cutters, as well as tools for fiber composites and plastics. Following the acquisition of the PWS precision tool competencies at the end of 2024, the portfolio also includes tools for roll shaping (modules 0.5–8.0) and roll piercing (modules 0.7–12). Production includes CNC grinding, post-grinding, coating, and re-profiling of cutting tools; processed materials range from steel, cast iron, and aluminum to titanium, PKD/PCD, CBN, and hardened steels up to 55 HRC. Customers come from Automotive, Aerospace, Mechanical Engineering, Robotics, Energy, and Medical Technology. The company employs around 800 employees at 13 global locations and is part of the family-owned LMT Group, which achieved a turnover of 377 million Euro in 2022.
