Frequently Asked Questions

What is a base jaw and what is its purpose compared to a complete jaw?

The base body (or base jaw) is the lower part of the top jaw system — it slides in the chuck's guides and receives the upper insert (the actual jaw). The base body is purchased when you want to replace only the worn lower part or when you want to build a customized clamping system by mounting specific inserts (soft, hardened, special profile) on a standard base body. The base body alone does not clamp — it requires the corresponding upper insert.

Is this Ø 315 mm base body compatible with my chuck?

DK12 series: DIN 6350 connection with 12 bolts. Verify that your chuck has this connection before purchasing. The Ø 315 mm size indicates the diameter of the chuck for which it is designed — not interchangeable between different sizes. Also, verify that the number of fixing bolts of the base body matches that of the chuck.

Are the upper inserts (top jaws) purchased separately?

Yes — the base body is designed to accommodate the top inserts of the STJ, TJ, DSTJ, DTJ series corresponding to the same size and connection. The inserts are purchased and replaced independently of the base body. Original spare parts available with 3–5 business day shipping. Customer service available in Italian.
