Benefit from rapid tool changes, secure eccentric clamping and a proven 0.01 mm repeatability for stable, high-throughput machining. The hardened and ground contact surfaces extend service life while 40 indexing positions allow fast retooling at 9° increments — order directly via Metav Werkzeuge or consult our specialists for application-specific advice.

TECWERK Quick-change Toolholder Head Gr. D1 — 40-position indexing, 40 mm bore

A TECWERK Quick-change Toolholder Head Gr. D1 designed for fast swaps of cutting tools in lathe and CNC toolpost systems, featuring eccentric clamping and industrial-grade repeatability.

• Eccentric clamp for secure rapid tool change
• Repeatability to 0.01 mm for consistent results
• 40-position indexing with 9° increments
• Hardened, ground gear and contact surfaces

Reduce downtime with faster, repeatable tool changes

The quick-change head uses an eccentric clamping mechanism to lock cutters reliably, enabling significantly reduced tool-change time compared with conventional fixtures. Because the system delivers a repeatability of 0.01 mm, process variation is minimised and set-up time for recurring operations is cut. Eccentric clamping converts a short lever action into strong radial force, so the head holds the cutting insert or holder firmly without complex tightening sequences — a practical advantage on busy turning centres and manual lathes where cycle time matters.

Flexible indexing and precise height adjustment for versatile set-ups

With 40 teeth in the indexing ring, each position corresponds to a 9° increment, allowing a wide range of tool angles without disassembly. The central bore of 40 mm accepts the mounting body, and three maximum overhang options (112 / 116 / 124 mm) permit selection according to reach and rigidity requirements. Tip height is set via a dedicated adjustment screw on the toolholder, which simplifies achieving correct centre height and avoids repeated scraping or shimming — an essential feature for shops that switch between facing, turning and profiling operations.

Hardened components for durable accuracy and low maintenance

The gearing and mating contact faces are hardened and ground, ensuring long-term resistance to wear and preserving datum accuracy even under repetitive indexing cycles. This construction reduces the need for frequent regrinding or replacement, supporting predictable maintenance intervals and lower lifetime cost of ownership. Built to integrate into workshop tool systems, the head is suited for demanding production environments where repeatable alignment and robust clamping determine part quality and process stability.

FAQ

Is the quick-change head compatible with standard toolposts?
Compatibility depends on the toolpost and mounting body interface; the TECWERK Quick-change Toolholder Head Gr. D1 is designed around a 40 mm bore and common D1-type interfaces, so matching the mounting shank or adapter is required for direct fitment.

How precise is the indexing and how is it achieved?
Indexing is achieved by a 40-tooth ring giving 9° increments; the mechanism provides secured positions and, together with the hardened contact faces, supports the stated 0.01 mm repeatability during re-clamping.

Can the tip height be fine-tuned after installation?
Yes, the tip height on the quick-change holder is adjusted by a set screw on the toolholder, enabling fine height correction without removing the head from the machine.

What are the implications of the different maximum overhangs?
Choosing between 112, 116 or 124 mm overhang balances reach against rigidity: shorter overhangs improve stiffness and reduce deflection, while longer overhangs permit greater access to larger workpieces.

Is the head suitable for heavy-duty production use?
The hardened, ground gear and main contact surfaces are specified for extended wear resistance, making the head well suited to repetitive production tasks where durable accuracy is required.
