TECWERK Weldon clamping holder HSK‑A63 — Weldon-style holder with 25 mm clamping Ø, A = 110 mm

The Weldon shank holder HSK‑A63 is a HSK‑interface toolholder designed to clamp cylindrical shank cutters with a lateral drive flat, suitable for machining applications where secure axial and radial locking is required.

• HSK‑A63 interface, DIN 69893 Form A
• 25 mm clamping diameter for Weldon shanks
• Bore tolerance H4 for precision fit
• Compact design: 65 mm diameter, A = 110 mm

Secure, standards-based clamping that reduces setup uncertainty

The holder uses the HSK‑A63 interface in accordance with DIN 69893 Form A, giving a rigid connection between spindle and toolholder that reduces runout and improves repeatability. With a 25 mm clamping capacity for tools with a lateral drive flat to DIN 1835‑B, the unit provides a reliable mechanical stop and positive torque transmission. The Bore tolerance H4 guarantees a tight fit at the mating surface, which helps maintain clamping accuracy during repeated tool changes and reduces the likelihood of vibration-related tool wear.

Compact form factor for tighter tool magazines and stable machining

With an outer diameter of 65 mm and an overall length A = 110 mm, the holder’s compact design permits installation in confined tool magazines without compromising rigidity. The short projection and robust construction improve stiffness at the cutting edge, which leads to better surface finish and extended tool life under typical milling and drilling loads. The Weldon-style lateral flat ensures axial retention while the HSK taper delivers radial support, creating a balanced connection for high-precision tasks.

Practical benefits for workshop and production environments

Engineered for repeatable performance in both single-machine shops and production cells, the holder accepts cylindrical shanks with a Weldon flat and clamps them securely for reliable machining cycles. The precise fit and standardised interface simplify inventory management—one adapter type covers a range of cutters—while the robust connection supports consistent process outcomes and reduced rework. The combination of standard compliance and mechanical simplicity supports quick changeovers and predictable setup times.

Compliance and traceability for consistent quality

Conformance to DIN 69893 Form A and compatibility with DIN 1835‑B tooling mean the holder integrates seamlessly into established HSK tooling systems. The clear specification and measurable parameters—clamping 25 mm, 65 mm diameter, A = 110 mm, and Bore tolerance H4—provide verifiable criteria for quality control and procurement. Supplied by TECWERK and listed as SKU 2000832397NW, the holder is described with the data necessary for procurement teams to compare options and ensure correct fitment.
