Wohlhaupter Precision Boring Systems
Pioneers of modular precision boring for over 85 years, tried and proven across Tier-1 German automotive leaders including Mercedes-Benz, Volkswagen, BMW, and Robert Bosch. From the versatile PrimeBore modular kit (Ø 6–128 mm) with 0.002 mm vernier accuracy, to the world-renowned MultiBore MVS connection with < 3 µm repeatability, and Alu-Line large-diameter tools spanning up to 3,255 mm.
