Precision & Innovation
ALMÜ Präzisionswerkzeug GmbH is a mid-sized company based in Zell unter Aichelberg at the foot of the Swabian Alb, specialising in the development, manufacture and distribution of precision and special tools for machining production. The portfolio includes PKD and PKD monoblock tools, VHM tools, drill/countersink combination tools, indexable-insert tools, the HSC-Flex cutter and hydraulic clamping fixtures. In addition, the company offers CNC parts production as contract manufacturing – with milling, turning, hard turning, wire EDM and grinding on machines from Grob, DMG, Heller, Chiron, Gildemeister and Studer – including heat treatment, coating, assembly of ready-to-install assemblies and logistics. Materials include aluminium, steel, cast iron, brass and plastics. Customers come from the automotive and supply industry, mechanical engineering, aerospace engineering, semiconductor equipment manufacturing and the consumer goods industry. With just under 40 employees, ALMÜ focuses on speed, precision and flexibility; since 2026 the company has been part of the Sandvik Group.
