Standard :
Similar to E-DIN 69882-8, form G.

Application :
For clamping tools with parallel shank to h6 tolerance.

Optional extras :
Pull studs (PS), No. 308760 − 308806,Shrink-fit chuck extension No. 302410 − 302417,Shrink-fit units No. 354210 − 354400.

High-temperature steel.Integral tool length adjustment, adjustment track 10 mm.Suitable for shrink fitting of HSS and carbide tools.All shanks hard turned (for smooth running!).With RFID/Balluffchip bore.

Advantage :
The double contact between the taper and the flat flange creates a more stable and precise clamping situation:Better surface qualityLonger tool life timesConsistent seating in the headstock (even at high speeds)Smaller radial run-outA BT double contact arbor can also be used in a standard BT machine spindle – and vice versa. The advantages of the double contact are however achieved only when a double contact arbor and double contact spindle are used together.
