Frequently Asked Questions
Are TF44 and F44 76-92 the same collet family?
They are commonly used as cross-references for the same dimensional family. Confirm the outside diameter, overall length, taper and machine application before ordering.
Does every 38 mm-class Swiss-type lathe use a TF44 collet?
No. Machines with a similar nominal capacity may use different collet dimensions. Confirm the machine model, tooling position and original tool.
Can TF44 collets be produced with hexagon or square bores?
Yes. PRONIXT reference capacities are Ø38 round, 32 AF hexagon and 27 AF square. Other profiles can be evaluated from a drawing or sample.
