124mm MT3 Taper Arbor With B12 Shank, Hardened And Ground, DIN 238 - TECWERK

The combination of a Morse taper 3 (MK3) seating and a B12 drill‑chuck arbor, together with a fully hardened and ground finish and a compact overall length of 124 mm, delivers secure mounting and long service life for routine workshop tasks; order via Metav Werkzeuge or consult their technical advisors for specification matching.

Taper arbor MK3×B12, hardened and ground – TECWERK

A taper arbor MK3×B12 designed for secure mounting of drill chucks on drilling and turning machines, compliant with DIN 238 and finished for consistent concentricity

• MK3 taper to DIN 238 standard
• B12 arbor for drill‑chuck mounting
• Fully hardened and ground construction
• 124 mm overall length for stable clamping

Secure mounting for reliable machining

The MK3 taper conforms to DIN 238, providing a standardised interface that ensures repeatable seating and low run‑out when used with compatible drill chucks. By combining the MK3 taper with a B12 arbor bore, the component creates a direct mechanical link between spindle and chuck, improving precision in hole‑making operations. This results in reduced rework and steadier tool behaviour during both drilling and light turning tasks, a rational advantage for workshops that prioritise measurable process stability.

Durability that reduces downtime

Manufactured in a fully hardened and ground execution, the arbor resists wear at the critical contact surfaces and preserves concentricity over extended service. The hardened finish limits fretting and deformation under repeated mountings, while the ground surface promotes accurate seating. Taken together, these properties extend maintenance intervals and contribute to predictable tooling performance, supporting efficient production flows in industrial and trade environments.

Compatibility and practical workshop use

With an overall length of 124 mm, the arbor offers compact handling and easy incorporation into existing setups. The design accepts standard drill chucks and is suitable for installation in drilling machines and lathes equipped to receive a Morse taper 3 spindle. The adherence to DIN 238 guarantees interchangeability with other standardised tooling, simplifying procurement and inventory management for maintenance departments and small workshops alike. The straightforward mechanical nature of the arbor makes it a practical, reliable choice for routine chuck mounting tasks.

FAQ

Which machines is the taper arbor suitable for?
The taper arbor MK3×B12 is intended for use on drilling machines and lathes that accept a Morse taper 3 spindle and is designed to receive standard drill chucks for general workshop applications.

How is the arbor mounted and secured?
Mount the MK3 taper into the spindle taper; the B12 arbor bore accepts the drill‑chuck mounting. The precise fits and DIN 238 conformity ensure stable seating and minimised run‑out for the chuck assembly.

What benefit does the hardened and ground finish provide?
The fully hardened and ground surface increases wear resistance at seating and contact zones, preserving concentricity and extending the service life of the arbor under frequent use.

Is the arbor suitable for precision drilling tasks?
Yes, the arbor’s standardised MK3 taper and careful finishing deliver the concentricity and secure clamping required for precise hole‑making with standard drill chucks.

Does the arbor meet international standards for interchangeability?
Compliance with DIN 238 ensures compatibility with other tooling produced to the same standard, simplifying replacement and integration into existing tool inventories.
