90mm MK1 Taper Shank With B12 Drill Chuck Mount, Hardened And Ground - TECWERK

Take advantage of a DIN 238 drill‑chuck taper with a true‑to‑size MK1 taper and a B12 chuck mount in one compact arbor; the hardened and ground finish ensures repeatable seating and long service life. Order the taper arbor directly via Metav Werkzeuge or consult the technical advisers for compatibility checks and fast delivery.

Taper arbor MK1 x B12, hardened and ground – 90 mm (TECWERK)

Taper arbor MK1 x B12, hardened and ground, for drill‑chuck mounting on drill and lathe spindles

• DIN 238 drill‑chuck taper
• Hardened and ground seating
• For drill and lathe chuck mounting
• Overall length 90 mm

Precise seating for accurate drill‑chuck mounting

The taper arbor provides a controlled interface between machine spindle and chuck: the MK1 taper mates to standard Morse‑taper spindles while the B12 bore accepts a matching drill chuck taper. Conformance to DIN 238 guarantees dimensional compatibility with common chucks and spindles, which reduces run‑out and wobble. With a fully hardened and ground finish, the arbor maintains concentricity over repeated mounting cycles, so operators benefit from consistently accurate hole positions and longer tool life.

Robust design for workshop reliability and low maintenance

Manufactured for daily workshop use, the arbor’s hardened and ground surfaces resist wear and minimise fretting between taper faces. This construction improves repeatability and lowers the need for frequent re‑setting or adjustment. The compact 90 mm overall length keeps the centre of mass close to the spindle, reducing overhang and vibration during drilling and light turning operations. Where dependable alignment matters, this component supports stable, efficient machining with minimal upkeep.

Clear standards and simple compatibility checks

Marked to the applicable standard (DIN 238), the arbor simplifies equipment matching: the MK1 external taper and B12 chuck mount form a direct, measurable specification for procurement and machine setup. For integrators and workshop managers, this removes ambiguity when specifying chucks or spindle adapters, enabling faster purchasing decisions and fewer returns. If uncertainty remains about compatibility with a specific chuck or spindle, Metav’s advisers can supply the necessary fit data and confirm suitability for the intended machine.

FAQ

Is this arbor compatible with standard drill chucks?
The taper arbor is manufactured to DIN 238 and accepts chucks with a B12 drill‑chuck taper, so it is compatible with standard B12 chucks when the machine spindle provides an MK1 external taper.

What does the hardened and ground finish mean for workshop use?
The hardened and ground finish on the arbor improves wear resistance and keeps the seating surfaces stable, which in turn reduces run‑out and extends the service life of both the arbor and the mounted chuck.

Can the arbor be used on lathes as well as pillar drills?
Yes. The arbor is intended for the mounting of drill chucks on both drill and turning machine spindles when the spindle taper is MK1 and the chuck uses a B12 mount.

How should the taper arbor be maintained to preserve accuracy?
Keep the taper faces clean and free from chips or coolant residue; periodic inspection and light cleaning before mounting helps preserve concentricity. The hardened and ground surface reduces servicing frequency compared with untreated components.

Which SKU identifies this product for ordering?
The product is listed under SKU 2000832312NW and supplied under the TECWERK designation for a taper arbor MK1 x B12, overall length 90 mm.
