Frequently Asked Questions
Are TF25, 145E and F25 76-64 the same collet?
They are common cross-references for the same general family. Confirm the outside diameter, length, taper and machine application before ordering.
Does every 20 mm Swiss-type lathe use a TF25 collet?
No. Machines with the same capacity may use different collet dimensions. Confirm the machine model, tooling position and original tool.
Can TF25 collets be produced with hexagon or square bores?
Yes. PRONIXT reference capacities are Ø20 round, 17 AF hexagon and 14 AF square. Other profiles can be evaluated from a drawing or sample.
