Turning Tool

About these products Robust HT300 material: Made of durable HT300 cast iron with 20Cr steel jaws (53 HRC) and a 40Cr steel worm (45 HRC), these chucks offer high hardness and corrosion resistance. The hardened construction ensures reliable performance with both small and large workpieces. High precision: Thanks to precise machining and a stable structure, these models guarantee accurate clamping performance. The self-centering 3-jaw versions feature a bevel gear and pinion for smooth power transmission. The bearing tolerance is ≤0.05 mm on selected models. Internal and external jaws: Depending on the model, the jaws are reversible, significantly expanding the clamping range. The clamping range extends from 2 mm to 250 mm, depending on the model, and allows for the secure clamping of various workpiece shapes. User-friendly design: The compact design with integrated self-centering allows for quick setup without recalibration. The T-shaped wrench allows for easy workpiece adjustment and secure clamping. Wide application: Suitable for turning, drilling, and milling on various lathes. The models in 80 mm, 160 mm, 200 mm, and 250 mm diameters cover a wide range of requirements in workshop and production environments. Key differences The K11-250 10' 3-jaw model offers a clamping range of 6–110 mm internal and 80–250 mm external with an 80 mm bore.
