32mm Combination Adapter Holder With 16mm Clamping, DIN 69871 Form AD/B - TECWERK

Benefit from a precise SK40 interface, a hardened and ground finish, and a 16 mm clamping bore that together deliver consistent concentricity and long tool life; order through Metav Werkzeuge or consult their specialists for application checks and compatibility advice.

Combination mounting milling arbor DIN 69871 AD/B – SK40, clamping Ø 16 mm (TECWERK)

The Combination mounting milling arbor is a DIN 69871 Form AD/B adapter designed for secure mounting of milling cutters with longitudinal or transverse keys in SK40 spindles for general machining and production environments

• Steep taper to DIN 69871 AD/B
• Hardened and ground for wear resistance
• Clamping bore 16 mm for cutter shanks
• A-length 55 mm for reliable axial support

Precision interface for repeatable machining results

The steep taper DIN 69871 Form AD/B provides a rigid, repeatable connection between spindle and toolholder that reduces runout and vibration during milling. The adapter's 16 mm clamping bore is intended for cutters with longitudinal or transverse keys, ensuring secure axial and radial placement of the shank. By using a standardised taper and a ground seating surface, the assembly improves repeatability across setups, which translates into fewer scrap parts and less rework on the shop floor.

Built for durability and low maintenance in production

Manufactured case-hardened and ground, this arbor resists wear at the seating and clamping zones, extending service intervals and maintaining concentricity over prolonged use. The hardened surface counters micro-movement under load, while the ground finish aids precise alignment with the spindle taper. For continuous or batch machining, this means a more stable cutting process and predictable tool life, supporting leaner production planning and reduced downtime.

Compatibility, mounting and practical benefits explained

The adapter is suitable for use with SK40 spindles and accepts milling cutters fitted with a longitudinal or transverse key. The specified A-length of 55 mm provides adequate axial support for most standard cutter shanks while keeping the tool projection manageable for accurate machining. Mounting is performed by seating the taper and securing the cutter in the clamping bore; if concentricity or runout is critical, a simple dial-indicator check after assembly confirms correct positioning. This approach delivers an efficient balance of rigidity and accessibility for tool changes.

FAQ

What spindle standard does this arbor fit?
The arbor conforms to DIN 69871 Form AD/B and is intended for use in SK40 spindles, providing a standardised, repeatable interface.

Which cutter shank types are supported?
The arbor accepts milling cutters with a longitudinal or transverse key and a clamping bore of 16 mm, ensuring secure axial locking of keyed shanks.

How is concentricity checked after mounting?
After seating the taper and clamping the cutter, a dial indicator on the cutter periphery is the recommended method to verify concentricity and runout.

Is the arbor suitable for heavy-duty milling cycles?
The case-hardened and ground construction increases wear resistance and stability, making the arbor appropriate for standard industrial milling tasks where a robust toolholder is required.

Can the arbor be re-ground or refurbished when worn?
Surface wear on the seating faces can be assessed by a tooling specialist; refurbishment depends on condition and must preserve the original taper geometry for safe use.
