Who is the 13 mm Drill Chuck with MK2 arbor for?
The 13 mm drill chuck with MK2 arbor is recommended for the following professional profiles:
-
Mechanical workshops and artisan turners: secure clamping of round or hexagonal workpieces on metal lathes during turning, drilling, and grooving operations.
-
Users with compatible flange Bernardo lathes: original replacement or upgrade for Bernardo range lathes (profi, hobby, etc.) with A2 attachment 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
What type of mounting does the 13 mm Drill Chuck with MK2 arbor have?
Check the indicated attachment (typically A2-5, A2-6, A2-8 according to DIN 55029) in the title or specifications.
The A2 flange mount is the standard for Bernardo Profi and Hobby range lathes. The number (5, 6, 8) indicates the flange size that must match the lathe's headstock.
How many jaws does it have and are they reversible?
Standard self-centering chucks have 3 jaws; typically supplied with 1 set of internal and 1 set of external reversible jaws plus a tightening key.
3-jaw chucks are suitable for round or hexagonal workpieces. For square or irregular workpieces, consider 4-jaw independent chucks. Soft jaws can be machined on the lathe for special applications.
What is the maximum rotation speed?
See "Max speed" in the technical table: typically 2,500-3,500 rpm for chucks up to Ø 200 mm.
The maximum speed decreases with diameter. Large chucks (Ø 400+ mm) typically have limits of 1,500-2,000 rpm. Exceeding the maximum speed risks jaw detachment.
What concentricity precision does it offer?
Professional Bernardo chucks comply with DIN 8386 class with typical concentricity of 0.03-0.04 mm.
Concentricity is critical for precision finishes. For high-precision machining (microns), higher-class chucks or dedicated clamping collets are needed.
How is it mounted on the lathe?
The chuck mounts directly onto the headstock flange via a camlock attachment for A2 systems.
The Camlock system allows quick mounting without an additional adapter flange. For lathes with a threaded connection, a dedicated adapter flange is required. Krollit supplies compatible flanges separately.
