TECWERK drill chuck arbor — DIN 69871 Form A, SK40 to B16

A TECWERK drill chuck arbor designed for secure mounting of B16 chucks on SK40 spindles, engineered for standard machining and retrofit applications.

• Steep taper to DIN 69871 Form A
• Accepts drill chucks to DIN 238 taper
• SK40 shank with B16 chuck cone

Reliable, repeatable chuck mounting for precision machining

The adaptor's steep taper compliant with DIN 69871 ensures a tight machine-to-tool interface that reduces runout and maintains concentricity during drilling and light milling. By using an industry-standard taper seat, the arbor provides mechanical rigidity and a predictable contact surface, which translates into more consistent hole quality and longer useful life for both chucks and spindles. The short overall length contributes to reduced overhang and improved stability in close-tolerance operations.

Broad compatibility for seamless integration into existing tooling

Designed to accept drill chucks made to DIN 238, the adaptor bridges common chuck cones and machine spindles without complex modifications. The SK40 shank delivers compatibility with a wide range of collet and taper holders, while the B16 chuck cone interface preserves established chuck mounting practice. This combination simplifies tool changes and reduces set-up times, offering a straightforward path to retrofit older machines or unify fixtures across a production group.

Practical shop design for dependable everyday use

With an effective length of 24 mm and a chuck-seat diameter A = 25 mm, the adaptor is compact and suited to workshops where space and accessibility matter. The single-piece configuration and standardised interfaces make it easy to store and identify among tooling sets; packaged per unit, it is ready for immediate use. For demanding production routines, the arbor supports predictable performance and helps to maintain process stability over repeated changeovers — a pragmatic choice for engineering and maintenance teams.

FAQ

What machine spindles is this arbor compatible with?
The TECWERK drill chuck arbor is compatible with spindles accepting an SK40 taper; the adaptor provides the DIN 69871 Form A interface and a B16 chuck cone for standard chuck mounting.

Can standard drill chucks be fitted to this adaptor?
Yes. The arbor accepts drill chucks produced to DIN 238, enabling direct mounting of industry-standard chucks onto an SK40 shank via the B16 interface.

What are the key dimensions to check before ordering?
Check the taper standard (DIN 69871), the shank type (SK40), and the chuck cone (B16). Relevant dimensions include the effective length L = 24 mm and the seat diameter A = 25 mm for correct fitment.

Is the adaptor suitable for heavy milling or only drilling?
The compact design and steep taper provide good rigidity for drilling and light milling; for heavy milling, select tooling specified for higher radial loads. The TECWERK arbor is optimised for stable chuck mounting and repeatable holemaking.

How is the item supplied?
The product is supplied as a single unit (packaging unit: 1) and is ready for installation in compatible tool-holding systems; refer to the item label for exact identification (SKU 2000832821NW).
