28mm Face Clamping Holder Weldon 8mm Shank HSK-A63 DIN 69893 Form A - TECWERK

Take advantage of the secure axial drive of the Weldon interface and the DIN‑compliant HSK‑A63 shank for consistent tool alignment; the compact 28 mm body with an 8 mm clamping bore reduces runout and simplifies tool changes. Order the Flächenspannfutter directly via Metav Werkzeuge or ask our consultants if needed.

Flächenspannfutter DIN 69893A – Weldon clamping, HSK‑A63 shank, 8 mm bore (TECWERK)

The Flächenspannfutter DIN 69893A is a face clamping holder designed for HSK‑A63 spindles, intended to clamp tools with a cylindrical shank and a lateral drive according to DIN 1835‑B.

HSK‑A63 shank to DIN 69893 Form A
Weldon flat for secure axial drive
Clamping bore Ø 8 mm with H4 tolerance
Compact Ø 28 mm body, length A = 65 mm

Precise interface and standardised compatibility for reliable toolholding

The holder features an HSK‑A63 connection complying with DIN 69893 Form A, which delivers high axial and radial stiffness at increased spindle speeds. The Weldon flat provides positive axial drive for tools with a lateral engagement surface, eliminating slippage under torque. The clamping bore of 8 mm manufactured to H4 tolerance ensures repeatable concentricity, reducing runout and improving finish quality on the workpiece. These characteristics make the component suitable where consistent tool position and low vibration are essential for productivity.

Faster set‑ups and reduced machining variation in daily workshop use

By combining a compact 28 mm diameter with an effective clamping interface, the holder shortens tool change and set‑up times while maintaining rigidity during cutting. Compatibility with tools to DIN 1835‑B means a wide range of cylindrical‑shank cutters can be used without adapters, lowering inventory complexity. Improved concentricity extends cutter life and reduces rework, which supports more predictable cycle times and a steadier production flow in both jobbing and series environments.

FAQ

What spindle interface does this holder use?
The holder uses an HSK‑A63 spindle interface compliant with DIN 69893 Form A, ensuring high stiffness and repeatable seating.

Is the clamping bore suitable for standard cylindrical shanks?
Yes, the 8 mm clamping bore (H4 tolerance) is intended for tools with a cylindrical shank and a lateral drive surface per DIN 1835‑B.

How does the Weldon flat improve clamping performance?
The Weldon flat provides a positive axial drive that prevents tool rotation under torque, improving axial positioning and reducing the risk of slippage during heavy cuts.

Can this holder reduce machining runout?
When mounted and clamped correctly, the combination of HSK‑A63 seating and the precision H4 bore contributes to reduced runout and more consistent surface finish.

What information is available for machine compatibility checks?
Technical data such as shank type, overall diameter, clamping bore and applicable norms (e.g., DIN 69893, DIN 1835‑B) are provided to verify compatibility with the spindle and tooling system.
