Quick-change tool holder head Gr. A — 48 mm overhang, 20 mm bore (TECWERK)

The Quick-change tool holder head Gr. A is a compact clamping solution for rapid interchange of turning tools in metalworking and precision turning applications.

• Eccentric clamping for secure fixation
• Repeatability 0.01 mm
• 40 indexable angles at 9° increments
• Hardened, ground serration and seating

Reduce set-up time with precise, repeatable tool changes

The head is engineered for fast tool swaps and consistent repositioning. Thanks to eccentric clamping and a specified repeatability of 0.01 mm, repositioning after tool changes is reliably precise, which reduces inspection cycles and downtime. For small-batch production and tool rooms where changeover speed and dimensional consistency matter, this head delivers measurable efficiency gains through fewer adjustments and less scrap.

Flexible angular positioning for versatile machining

A 40-tooth indexing system provides 40 distinct angular positions, each separated by 9°, enabling flexible orientation of the cutting edge without additional fixtures. The combination of indexed positions and compact design supports complex turning and profiling tasks while maintaining repeatable geometry. This indexed arrangement simplifies tool set-up, so multiple tool types can be arranged quickly and returned to a defined orientation.

Durable contact surfaces and secure seating for process reliability

Contact interfaces — the serration and the flat seating face — are hardened and ground to resist wear and maintain clamping fidelity under repeated cycles. The hardened surfaces help preserve the original fit and repeatability over prolonged use, supporting long-term process stability. Where repeatable accuracy is required across many change cycles, this durability reduces maintenance interventions and contributes to consistent part quality.

Compact dimensions and straightforward height adjustment

Designed with a 20 mm bore diameter for the central body and a maximum overhang of 48 mm, the head suits compact tool posts and restricted spaces without compromising reach. The tip height is set via a dedicated adjustment screw on the turning-tool holder, allowing precise alignment of the cutting point with minimal tools required. These compact mechanical features support tidy tool layouts and rapid alignment on the lathe.

FAQ

How precise is the positioning after a tool change?
The TECWERK quick-change tool holder head provides a repeatability of 0.01 mm, ensuring reliable repositioning after each swap.

What bore size is required for mounting this head?
A 20 mm central bore diameter is specified for the body, which matches standard compact tool posts and adaptors.

How far can the tool project from the mounting centre?
The maximum overhang is 48 mm, measured from the bore centre to the end edge of the interchangeable holder.

How are angular adjustments made and how fine are the steps?
Angular indexing is achieved via a 40-tooth system, giving 9° increments for defined orientation of the cutting tool.

Are the contact surfaces durable for high-cycle use?
Yes — the serration and the flat seating face are hardened and ground to resist wear and preserve clamping accuracy over repeated cycles.
