ER-Precision collet chuck SK 50 - 2/20 - 125 | 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

For sealing tools with internal cooling in collet chucks

Low-vibration boring barsWith internal coolingLonger durability of insertsFor longitudinal and plane turningSetting angle: 93°Delivery: without inserts

The clamping screw incorporates a through hole

All tool sizes can be combined

Improves chip evacuation and decreases the risk for chip jamming

without the illustrated cutting tools

Collets sealed for high pressure cooling 120 bar with IC DIN 6499 B (ISO 15488 B) ER-system

clamping depth = 58

the coolant tube can be moved only to a minimum degree according to DIN (±1°)

Adapters HSK / PSK with axial clamping

Hydraulic or manual clamping
