ER-Precision collet ER40 | 472EP | < 5µm | Ø 7 - 6

ER-Precision collet ER40 | 472EP | < 5µm | Ø 7 - 6Application: For mounting straight shank tools in collet chucks DIN 6499. To use for high speed cutting and high precision milling. Note: High flexibility: Large holding capacity up to 1 mm

d = 40/d = 60: For large diameter face mill cutters with four additional threaded holes according to DIN 2079

With built-in tightening bolt

Minimal length compensation on compression and expansion balances very small pitch differences between synchro spindle and tap

Taper angle tolerance < AT 3 according to DIN 2080

shank form UF

low warpage hardened

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance3

For mounting tools with Morse taper shank and tang according to DIN 228-1 form B

Collets sealed with seal for IC

Only nominal size d can be clamped with sealing plug for internal cooling (applicable up to 21 bar) In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet
