50mm Tool Holder HSK-A63 ER Collet Chuck 2-20mm Clamping Range, DIN 69893 Form A - TECWERK

Reliable, rigid toolholding with an HSK‑A63 spindle interface, a broad 2–20 mm clamping range and a 100 mm projection delivers repeatable precision and efficient spindle use; order the TECWERK ER collet chuck directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK ER Collet Chuck HSK‑A63 — ER32, 2–20 mm, A = 100 mm

The TECWERK ER Collet Chuck HSK‑A63 is a DIN 69893 Form A toolholder for secure clamping of cylindrical‑shank cutting tools in ER collets, engineered for high‑precision milling and drilling applications.

• DIN 69893 Form A HSK‑A63 interface
• ER collet chuck, clamping range 2–20 mm
• 100 mm projection length A for extended reach
• 50 mm flange diameter for rigid mounting

Increased process reliability through a standardised spindle connection

The hollow shank taper to DIN 69893 Form A provides a direct, form‑fit connection between spindle and toolholder, delivering high radial stiffness and minimal runout. This geometry, combined with the HSK‑A63 interface, reduces micro‑movement under load and contributes to repeatable tool positions across setups. For production environments where spindle accuracy affects surface finish and tool life, this toolholder offers a measurable improvement in process consistency and reduced rework. The compact flange with a 50 mm diameter supports stable clamping while maintaining compatibility with common HSK tool systems.

Flexible inventory and straightforward clamping for diverse tooling

Equipped for ER32 collets, the chuck covers a wide 2–20 mm clamping range, making it suitable for a broad mix of end mills, drills and reamers with cylindrical shanks. ER collets conforming to DIN 6499 self‑centre and compensate minor shank tolerances, so fewer collet sizes are required to cover typical tool inventories. This versatility shortens changeover time and simplifies toolroom logistics, enabling shops to standardise on one chuck type for multiple machining tasks without compromising grip or concentricity.

Practical dimensions that favour stability and accessibility

With a functional projection length A = 100 mm, the toolholder balances reach and rigidity for operations requiring extended tool reach while keeping deflection low. The design’s hollow shank taper also supports coolant through the spindle where configured and is suited for modular toolholding strategies. Clear labelling of standard dimensions and adherence to DIN interfaces streamline procurement and replacement planning, reducing downtime and helping maintain throughput. The chuck’s construction is focused on reliable clamping performance and uncomplicated maintenance routines for industrial use.

FAQ

What clamping range does the chuck cover?
The chuck covers a 2–20 mm clamping range when used with ER32 collets, allowing a broad selection of cylindrical‑shank tools to be held securely.

Is this toolholder compatible with HSK‑A63 spindles?
Yes, the toolholder is designed for the HSK‑A63 interface and complies with DIN 69893 Form A, ensuring a form‑fit connection with HSK‑A63 spindles.

Which collet size is required for the system?
The system uses ER32 collets for the stated clamping range; ER32 collets to DIN 6499 should be used to guarantee correct centring and clamping performance.

What are the key dimensions that affect tool reach and rigidity?
Key dimensions are projection length A = 100 mm and flange diameter D = 50 mm, which influence available tool reach and the overall stiffness of the assembly.
