Shanks hard turned. With Balluffchip bore. The collet is clamped by a threaded connection from behind through the chuck, no clamping nut required. Advantage: Extremely slim design permits machining of components where access is difficult, e.g. during toolmaking and mould-making. Application: For clamping tools with plain shank to DIN 6499. Supplied with: Clamping screw and wrench with T-handle. Optional extras: Pull studs (AB) No. 308600 - 8806, PS pull stud wrenches No. 308820 / 8830, collet No. 309563.
