T-slots for your requirements

Our precision machine tools incorporate slots in all dimensions & distance intervals

Cast constructions from Stolle offer many different clamping options for all types of workpieces. We use computer-controlled precision machines to work the longitudinal and latitudinal slots required for this purpose into our products.


The T-slots can be designed individually to suit your requirements – in all dimensions and spacings on request.


Size of the T-slots

The size of the T-slots in the plates is determined by the tensile and pressure forces that occur. All standard dimensions in the sizes 14, 18, 22, 28, 36 or 42 can be fitted in accordance with DIN 650 H7 bis H12.

Spacing of the T-slots

The T-slot spacing of our standard products is 150, 200, 250 and 300 mm.

If several tooling plates are combined to form plate fields, the distance to the plate joints should be half of the slot spacing distance in each instance. This results in the even distribution of the slots over the entire surface.
