ER-Precision collet chuck SK 50 - 2/20 - 200 | ER 32Application: For mounting straight shank tools in 2 m collets. Advantage: Excellent concentricity in the system (chuck + collet + clamping nut) 3 m radial run out with a 2 m clamping nut, 6 m radial run out with a 5 m clamping nut Extremely strong holding force (increases the holding power by at least 60% compared to standard ER chuck) Plain clamping nut without grooves for high speed machining

Clamping positions: horizontal

For mounting straight-shank tools in collets
