Quick-change toolholder head Gr. B TECWERK — eccentric clamping, 40 index positions

Quick-change toolholder head Gr. B TECWERK is designed for rapid tool changes in lathe and turning applications, offering high repeatability and robust, hardened contact surfaces

• Eccentric clamping for quick tool changes
• Repeatable positioning to 0.01 mm
• Hardened, ground gearing and seating
• 40 index positions in 9° steps
• 32 mm central bore and 71 mm overhang

Precision and process reliability for turning operations

The quick-change toolholder head delivers a measurable improvement in set-up speed and process stability thanks to its eccentric clamping system and confirmed 0.01 mm repeatability. The eccentric clamp secures cutting tools quickly while maintaining the repeatable position required for serial production, which reduces downtime between operations and minimises rework. For workshops and job shops that value consistent results, the unit’s measured indexing and firm seating reduce setup variability and support predictable cycle times.

Flexible positioning for multi-angle tooling

With 40 index positions at approximately 9° increments, this holder head enables a wide range of tool orientations without the need for separate fixtures, allowing machining strategies to be adapted on the fly. The ability to set different tool angles within a single holder supports complex facing, profiling and finishing tasks while keeping the toolcentre height adjustment straightforward via the integrated set screw. This flexibility translates into fewer tool changes on the machine and a leaner tool inventory.

Robust construction for demanding shop use

Critical contact areas are hardened and ground, providing a durable seating surface that resists wear and preserves alignment over time. The central 32 mm bore and the structural design accommodate stable mounting, while the maximum 71 mm overhang suits operations requiring extended reach. These characteristics combine to deliver a component that withstands the mechanical stresses of heavy turning and repeated index cycles, prolonging service life and reducing maintenance frequency.

Practical handling and compatibility in production

The head’s design focuses on fast handling: tool swaps are completed with the eccentric locking action, and the tip height of the turning tool is adjusted securely using the set screw on the tool post. Because the clamping and locating faces are precision-ground, repeatability is largely independent of operator skill, which supports consistent quality across different shifts and operators. For integration into existing setups, the component’s dimensions and index resolution make it suitable for a wide range of conventional and CNC lathes, provided the spindle and turret interfaces match the 32 mm centre bore.

FAQ

What level of repeatability can be expected from this holder head?
The Quick-change toolholder head Gr. B TECWERK provides repeatable positioning to 0.01 mm, ensuring reliable tool location across repeated changes.

How many angular settings are available and what is the step size?
The unit offers 40 index positions, each at approximately 9°, enabling a broad range of tool orientations without additional fixtures.

What bore size is required for mounting this head?
The component uses a 32 mm central bore, which must match the turret or adapter interface for correct mounting.

Is the tip height adjustable and how is it set?
Tip height is adjusted on the turning tool using the built-in set screw on the toolholder, allowing precise height correction after indexing.

Are the contact surfaces durable for serial production?
Yes. The gearing and planing contact surfaces are hardened and ground, providing wear resistance and stable seating for repetitive production runs.
