Frequently Asked Questions
Are TF30, 157E and F30 76-63 the same collet?
They are commonly used as cross-references for the same general dimensional family. Confirm the outside diameter, overall length, taper and machine application before ordering.
Does every 25 mm-class Swiss-type lathe use a TF30 collet?
No. Machines with a similar nominal capacity may use different collet dimensions. Confirm the machine model, tooling position and original tool.
Can TF30 collets be produced with hexagon or square bores?
Yes. PRONIXT reference capacities are Ø25 round, 21 AF hexagon and 17 AF square. Other profiles can be evaluated from a drawing or sample.
