TECWERK Quick-change tool holder head Gr. AA — eccentric clamping, 40 indexing positions

The TECWERK quick-change tool holder head Gr. AA is a compact clamping interface for rapid exchange of cutting tools while preserving high positioning accuracy in turning and live tooling applications.

*Eccentric clamping for fast exchanges
*Repeatability of 0.01 mm for consistent set-ups
*40 indexing positions at 9° increments
*Hardened and ground gearing and contact faces

Faster changeovers with industrial repeatability

The design centres on eccentric clamping, enabling quick replacement of cutting inserts and holders without lengthy re‑alignment procedures. Thanks to a declared repeatability of 0.01 mm, setups remain consistent across tool swaps, which reduces scrap and shortens machine idle time. For production environments where cycle time and reliable tolerances matter, this component provides a measurable productivity gain without extra calibration effort.

Precise angular positioning for indexed tooling

A hardened tooth ring with 40 indexing positions allows positional adjustments in 9° steps, offering flexibility when arranging tool angles or using multiple insert types. The hardened and ground gear and support surfaces deliver repeatable seating and low backlash; this ensures that each indexed position returns to its nominal orientation and maintains cutting geometry, which is especially beneficial for multi‑operation tool turrets and modular tool systems.

Compact reach and secure central bore

With a 12.5 mm centre bore and a 30 mm maximum reach, the tool holder head suits compact toolholders and short overhang configurations where rigidity is critical. The centre bore facilitates secure mounting to the central body, while a simple set screw allows fine adjustment of tip height, removing guesswork during final set-up. The combination of a short projection and precise adjustment reduces deflection and improves surface finish on turned components.

Robust construction to lower maintenance needs

Critical contact areas are hardened and ground, improving wear resistance and ensuring a long service life under repetitive indexing and clamping cycles. The eccentric clamping mechanism is engineered for reliable retention and quick action, which lessens the likelihood of unplanned stops for rework. When paired with proper maintenance intervals, this tool holder head supports sustained machine availability and predictable process capability.

FAQ

What degree of repeatability can be expected from this tool holder head?
The TECWERK quick-change tool holder head Gr. AA delivers a repeatability of 0.01 mm, ensuring consistent return to the preset position after each exchange.

How many angular positions does the index allow and what is the step size?
The tool holder head provides 40 indexing positions, each corresponding to a 9° increment for precise angular adjustment.

Which bore diameter and maximum reach are provided?
The central bore measures 12.5 mm and the maximum reach from bore centre to end edge is 30 mm, facilitating compact and rigid mounting.

Is the contact surface wear-resistant for high-frequency use?
Yes, the contact faces and the tooth ring are hardened and ground, improving wear resistance and maintaining seating accuracy over many cycles.

Can the cutting tip height be adjusted after mounting?
Tip height is settable via a set screw at the toolholder, allowing fine correction without removing the assembly.
