TECWERK face clamping chuck HSK‑A63 with internal cooling, Weldon clamping Ø16 mm

The TECWERK face clamping chuck is a high‑precision toolholder designed for CNC machining and milling, offering an HSK‑A63 interface and integrated coolant delivery for reliable clamping and enhanced tool life.

• HSK‑A63 interface DIN 69893 Form A
• Internal cooling with side coolant channels
• Weldon flat to DIN 1835 B for secure drive
• Clamping Ø 16 mm, outer Ø 48 mm, length 80 mm

High precision and system compatibility for CNC machining

The holder combines an HSK‑A63 connection compliant with DIN 69893 Form A and a compact body for predictable spindle engagement. This design ensures excellent repeatability and radial stability at high spindle speeds, which is essential in production environments where tolerance adherence is non‑negotiable. The toolholder supports consistent chip‑to‑chip accuracy and simplified setup when integrated into standard HSK tool‑change systems on modern machining centres. With this mechanical basis, process planners gain measurable improvements in part quality and reduced scrap rates.

Active coolant routing that extends tool life

Built‑in internal cooling and side coolant channels provide directed coolant to the cutting zone for tools with cylindrical shanks. By delivering coolant close to the cutting edge, the holder reduces thermal load and improves chip evacuation, which in turn increases tool life and surface finish quality. For operations that demand longer uninterrupted cycles, the improved cooling performance translates into fewer tool changes and lower overall machining costs, while maintaining tight dimensional results even in demanding materials.

Secure torque transmission and quick, repeatable clamping

The lateral drive surface conforms to DIN 1835 B (Weldon flat), providing a positive drive for cylindrical shank tools and preventing slippage under high axial or torque loads. This mechanical interface combines with the clamping mechanism to deliver fast, reliable tool changes and consistent axial run‑out values. The combination of the Weldon flat and the compact shank geometry is particularly suitable for heavy milling and finish passes where tool retention and concentricity are critical.

Practical workshop benefits and procurement advantages

With an outer diameter of 48 mm and a projection/length of 80 mm, the holder fits common tool configurations without adding excessive overhang, supporting rigid setups and easier tool access. The compact form factor, standardised interface and coolant capability simplify tool inventory and reduce the variety of specialised holders required. For purchasing teams and workshop managers, this means fewer suppliers, quicker selection decisions and dependable repeatability from a single, robust toolholder family.

FAQ

What spindle interface does this chuck use?
The TECWERK face clamping chuck uses an HSK‑A63 spindle interface in accordance with DIN 69893 Form A (SKU 2000833840NW), ensuring compatibility with HSK‑A63 toolholders and spindles.

How is cooling supplied to the cutting edge?
Cooling is provided via internal cooling plus side coolant channels, which deliver coolant close to the tool tip for improved tool life and chip control when using cylindrical shank tools.

What clamping diameter is available with this holder?
The holder provides a clamping Ø of 16 mm, suitable for cutters and arbors that require a secure Weldon‑style drive and positive torque transmission.

Is the drive interface a standard Weldon flat?
Yes — the product features a lateral drive surface manufactured to DIN 1835 B, commonly referred to as a Weldon flat, for reliable axial and torsional transmission.

What are the main dimensional references for workshop planning?
Key dimensions are outer Ø 48 mm and a projection/length A = 80 mm, which support rigid setups with limited overhang.
