TECWERK Weldon Face Clamping Holder HSK-A63 – 20 mm clamping diameter, 80 mm length

The TECWERK Weldon Face Clamping Holder HSK-A63 is a hollow-shank taper holder built to DIN 69893 Form A standards for secure clamping of tools with cylindrical shanks and lateral drive flats

• HSK-A63 hollow-shank taper DIN 69893 Form A
• Weldon flat for secure lateral drive
• 20 mm clamping diameter for cylindrical shanks
• Compact Ø 52 mm body, 80 mm projection length

Stable interface for precision tooling and repeatable results

The holder features an HSK-A63 hollow-shank taper manufactured to DIN 69893 Form A, which delivers a repeatable mechanical interface between spindle and tool. This standardised taper, combined with the Weldon lateral drive, reduces slip under torque and improves positional repeatability during interrupted cuts. The controlled 20 mm clamping diameter is optimised for tools with a cylindrical shank and a drive flat to DIN 1835‑B, translating into predictable tool behaviour and fewer changeover adjustments in series production.

Compact design that preserves machine dynamics and accessibility

A compact body diameter of 52 mm and a projection length of 80 mm minimise overhang while still accommodating common tool lengths, supporting higher spindle speeds and reduced vibration compared with longer holders. The reduced envelope improves access to tight fixtures and lowers inertial forces at the cutting zone, which contributes to longer tool life and steadier surface finishes. Integration into HSK-A spindles is straightforward thanks to the hollow-shank geometry.

Standard conformity and practical compatibility for workshop use

Built to comply with industry norms, the holder is suitable for clamping tools with cylindrical shanks and a lateral drive flat as specified in DIN 1835‑B, ensuring interchangeability across compatible tool sets and machines. The Weldon feature provides a clear mechanical drive interface that prevents rotation of the tool under side loads. The standardised interface simplifies tool inventory management and supports reliable set-up procedures in both jobbing and production environments.

Suitable for demanding machining applications and streamlined logistics

The holder is designed for use in milling and drilling operations where precise axial and radial restraint is required. With its standardised interfaces and compact form, this clamping solution integrates easily into existing tool-change workflows and supports faster set-up times. For operators seeking a balance of rigidity and space efficiency, the TECWERK Weldon Face Clamping Holder HSK-A63 represents a practical component to keep machines productive and predictable.

FAQ

What spindle interface does this holder use?
The holder uses an HSK-A taper (HSK-A63 as specified) per DIN 69893 Form A for a standardised spindle-to-tool connection.

Which tool shank types are compatible with this clamping holder?
Compatibility covers tools with a cylindrical shank and a lateral drive flat to DIN 1835‑B; the holder clamps a 20 mm shank securely.

What are the key dimensional values to check for machine fitment?
Relevant values: body diameter 52 mm, clamping diameter 20 mm, projection length A 80 mm; verify these against machine tool envelopes.

How does the Weldon flat improve tool retention?
The Weldon flat provides a mechanical lateral drive that prevents rotational slip under torque, enhancing retention when used with tools meeting the DIN 1835‑B flat specification.
