Face Clamping Chuck HSK-A63 — TECWERK — 8 mm clamping Ø, internal coolant

The Face Clamping Chuck HSK-A63 is a precision toolholder designed for secure clamping of 8 mm Weldon shank tools in machining centres, featuring internal coolant and lateral drive per DIN 1835 B.

• HSK-A63 taper to DIN 69893 Form A
• 8 mm clamping diameter for Weldon shank
• Internal coolant with lateral coolant channels
• Lateral drive surface to DIN 1835 B

Rigid interface for consistent accuracy and repeatability

The HSK-A63 interface, conforming to DIN 69893 Form A, provides a hollow shank taper that prioritises repeatable concentricity and axial rigidity. With a projection of A = 65 mm and outer diameter D = 28 mm, this toolholder reduces runout and vibration compared with longer, less supported solutions. The combination of a short overhang and solid clamping system supports precise tool positioning; the Weldon-style 8 mm clamping offers straightforward tool retention for cylindrical shanks while maintaining tool stability during moderate cutting forces.

Integrated cooling and reliable tool support for longer tool life

Equipped with internal coolant and lateral coolant channels, the chuck improves coolant delivery directly to the cutting zone for better chip flushing and temperature control. This setup is particularly effective with cylindrical-shank cutters, as coolant channels reduce heat build-up and extend insert and tool life. The presence of a lateral drive surface to DIN 1835 B ensures positive torque transmission for Weldon shanks, combining mechanical drive with efficient cooling to support consistent process results and reduced rework.

Compatibility and precision features that simplify setup

Designed for HSK systems and centred on workshop compatibility, the face clamping chuck accepts Weldon-clamped tools with an 8 mm clamping bore and maintains a bore tolerance H4 for accurate fitment. Conformity to recognised standards streamlines integration into machines with an HSK-A spindle interface and ensures interchangeability across paired toolholders. For operations seeking reduced setup time and predictable repeatability, the unit’s technical design supports faster tool changes and dependable performance in milling or drilling applications where rigidity and coolant management are priorities.
