TECWERK tool holder for boring bars — Type A, Form E2 S, 16 mm clamp (VDI40)

The TECWERK tool holder for boring bars is a slotted, through-drilled VDI40 holder designed for precise clamping of 16 mm boring bars and optimised for coolant-fed operations in general workshop and production environments.

• Slotted design reduces vibration and chatter
• Through-drilled shank for internal coolant
• Secure retaining ring prevents ejection
• Compatible with VDI40 systems and DIN 69880

Consistent accuracy and reduced vibration for finer finishes

The slotted E2 S form provides an embracing clamp that reduces radial play and damps vibration, which directly improves surface finish and extends insert and bar life. With a clamping diameter of 16 mm and a robust outer diameter of 50 mm, the holder keeps runout to a minimum during boring operations. Reduced chatter not only enhances component quality but also lowers rework rates, delivering a measurable efficiency gain on repeat production runs.

Coolant-ready construction to maintain cutting performance

Designed through-drilled, the shaft allows both external and internal cooling, ensuring consistent heat removal at the cutting edge. This enables longer uninterrupted cycles and supports higher cutting parameters where appropriate, because coolant reaches the tool tip directly. For workshops aiming to boost material removal rates while preserving tool life, the holder’s coolant compatibility offers a practical route to higher throughput without compromising component tolerances.

Secure mounting and standardised interface for easy integration

Compliance with DIN 69880 and the VDI40 interface guarantees straightforward integration into existing turret and toolholders. The retaining ring secures the bar against accidental ejection into the turret, while the slotted area accommodates fully round boring bars with a V-groove. Clamping depths are specified for various diameters (slotted area: up to 16 mm at 4×D; 20 and 25 mm at 3×D; from 32 mm at 2.5×D), aiding correct selection for stable tooling setups and predictable performance across part families.

Workshop practicality and adjustable installation for reliable uptime

The holder’s shaft is drilled where possible to permit length adjustment from the shank side, easing set‑up and shortening changeover times. Constructed for routine workshop use, the compact overall length (L 95 mm, L1 73 mm) and clear adherence to VDI standards make maintenance, storage and inventory management simpler. The combination of straightforward adjustments and secure fixing reduces downtime and supports consistent output in both single‑piece and batch machining contexts.

FAQ

What materials is this holder intended for?
This TECWERK tool holder for boring bars is designed as a general-purpose holder suitable for a wide range of materials when combined with the correct boring bar and insert selection; machining parameters should be adapted to the specific material.

Can internal coolant be used with this holder?
Yes, the holder is through-drilled, enabling internal coolant supply as well as external coolant, which helps maintain cutting-edge temperature and flushing.

Is the holder compatible with standard turret systems?
The holder uses the VDI40 interface and conforms to DIN 69880, ensuring compatibility with standard turret-mounted systems that accept VDI tooling.

How does the slotted design affect machining quality?
The slotted, wrap-around clamp reduces radial play and damps vibration, resulting in improved surface finish and extended tool life for consistent production quality.

Is the boring bar secured against falling into the turret?
Yes, the design includes a retaining ring that secures the bar and prevents accidental ejection into the turret during operation.
