Who is the B16 1–13 mm self-tightening precision chuck for?
The B16 1–13 mm self-tightening precision chuck is recommended for the following professional profiles:
-
Mechanical workshops and artisan turners: secure clamping of round or hexagonal workpieces on a metal lathe for turning, drilling, and grooving operations.
-
Users with a Bernardo lathe with a compatible flange: original replacement or upgrade for Bernardo range lathes (profi, hobby, etc.) with A2 taper compliant with DIN 55029.
-
Irregular or non-round workpieces: for non-symmetrically centered workpieces, consider 4-jaw independent chucks or universal faceplates.

Frequently Asked Questions
When to use this chuck?
It is a self-centering chuck for clamping workpieces on the lathe during turning operations.
Self-centering chucks allow quick clamping of the workpiece with a single key. The choice depends on the shape of the workpiece (cylindrical, square) and the material of the body (steel or cast iron).
What material is the chuck body made of?
The material is indicated in the title: steel (PO series) for maximum precision, cast iron (DK/PS series) for standard use.
The choice depends on the intensity of use and the required tolerance: steel for production and precision, cast iron for general use.
Which diameter should I choose?
The choice of diameter depends on the lathe spindle nose (it must match the mounting) and the dimensions of the workpieces to be machined.
Typical diameters: 80-160 mm for hobby lathes, 200-315 mm for professional lathes, 400-630 mm for industrial lathes.
How do I check compatibility with my lathe?
Check the type of mounting on the lathe spindle nose (Camlock D3-D15, or threaded M-taper) and the corresponding diameter.
On modern lathes, Camlock mounting is the most common. On older lathes, there may be a threaded (M-) or flanged taper. The lathe's technical documentation indicates the exact type.
How is chuck precision maintained?
Regular cleaning of the spiral mechanism, periodic lubrication with specific chuck grease, concentricity check every 6 months with a dial indicator.
A jaw that moves with difficulty indicates chips or rust in the mechanism: disassemble, clean, and grease. Concentricity is checked by mounting a ground bar and measuring with a dial indicator: acceptable tolerance 0.03-0.1 mm depending on the model.
