Sealing disc | ER 40 DCONWS = 1,5Application: For sealing tools with internal cooling. Note: Sealing capacity up to 80 bar Clamping range 0. 5 mm (+0. 1 ? 0. 4)

Surface hardened HRC 58~60

For sealing tools with internal cooling in collet chucks

Mainly for external machining

In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet

- Rustproof

Taper angle tolerance < AT 3 according to DIN 2080

Tensile strength in the core of min

For sealing the spindle of the turret

Sealing capacity up to 80 bar

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance

For safe clamping of taps

Only nominal size d can be clamped
