TECWERK E2 S Toolholder for Boring Bars (VDI30, 16 mm clamping)

TECWERK E2 S Toolholder for precision boring applications, compatible with VDI30 interfaces and designed to reduce vibration and enable internal cooling

• E2 S slotted design reduces vibration
• Through‑drilled shank for internal cooling
• Secured against falling out with retaining ring
• Compatible with VDI30, 16 mm clamping diameter

Stable clamping for precise boring results

The E2 S slotted design is engineered to dampen oscillation and reduce vibration during cutting, which directly improves surface finish and dimensional stability. With a clamping diameter of 16 mm and a VDI30 interface, the holder provides a defined, repeatable connection between machine and boring bar; this decreases setup variability and supports consistent batch production. For workshop managers, the measurable outcome is fewer rejects and less rework thanks to the enhanced stability of the machining system.

Cooling and chip control that keep cycles running

A through‑drilled shank enables both internal and external cooling, permitting coolant to reach the cutting edge and lower cutting temperatures. Cooler cutting conditions reduce tool wear and preserve insert geometry, so cycle times remain stable over longer runs. The option for internal coolant supply is particularly beneficial for deep boring or hard-to-access cavities where external cooling alone is insufficient, improving process reliability and reducing the frequency of unscheduled tool changes.

Secure mounting and straightforward length adjustment

The holder is secured by a retaining ring, preventing accidental release into the turret and reducing downtime from tool retrieval. Shafts are drilled where feasible to allow length adjustment from the shank side, enabling fine alignment without removing the holder from the machine in many cases. The component’s overall length of 95 mm and a functional length of 73 mm make it suitable for a broad range of turret and toolpost arrangements while keeping the centre of gravity compact for reduced runout.

Standard conformity and on‑machine compatibility

Built to DIN 69880 and matching the VDI30 taper system, this toolholder integrates with standard turret configurations and is also suitable for fully round boring bars with a V‑groove. The slotted area accommodates several bar diameters (up to 16 mm at 4×D, 20 and 25 mm at 3×D, and from 32 mm at 2.5×D), offering versatility across different tooling setups. The standardised interface shortens commissioning time and simplifies inventory management for production environments that rely on interchangeable clamping solutions.
