Face clamping holder HSK‑A63, Weldon flat, 6 mm clamping – TECWERK

Face clamping holder HSK‑A63, Weldon flat, ideal for clamping DIN 1835‑B cylindrical shanks in milling and drilling toolholders

• HSK‑A63 interface to DIN 69893 Form A
• Weldon flat for secure lateral drive
• Clamping Ø 6 mm for cylindrical shanks
• Bore tolerance H4 for precision fit

Precise, repeatable clamping for productive setups

The HSK‑A63 taper in accordance with DIN 69893 Form A provides a defined seating that improves repeatability between tool changes. Combined with the specified bore tolerance H4, the holder ensures a tight, consistent fit of the clamping element, which reduces runout and the need for frequent readjustment. This leads to shorter setup times and more predictable machining results when processing batches or switching tools frequently.

Secure drive and broad compatibility with cylindrical shanks

Equipped with a Weldon flat, the holder provides positive lateral engagement for tools with a driving face as per DIN 1835‑B, avoiding slippage under torque. The clamping Ø 6 mm is suited to common tool shank sizes that rely on a Weldon-style side drive, while the HSK‑A63 interface guarantees compatibility with machines designed for DIN 69893 Form A toolholders. The specified dimensions (A = 100 mm; D = 25 mm) support integration into standard tool chains without modification.

Designed for workshop efficiency and confident procurement

A compact length and standardised interface mean easier stock management and faster replacement when tools need swapping. The combination of a standardised HSK connection and a Weldon lateral drive delivers operational security for a wide range of milling and drilling operations. Where tolerance-sensitive applications are required, the bore tolerance H4 and the secure drive design contribute directly to consistent part quality and reduced scrap rates.
