Toolholder E2 S DIN 69880 (Type B) – VDI40, 32 mm clamping by TECWERK The Toolholder E2 S (Type B) secures boring bars in VDI40 toolholders and is engineered for reduced vibration and coolant flexibility in medium-duty turning and boring operations. Slotted design reduces vibrations Compatible with VDI40 spindles Secured by retaining ring against ejection External and internal coolant options Stable clamping that increases process reliability The slotted, Form E2 S construction is designed to wrap around the boring bar and deliver consistent radial support. This results in reduced vibrations and a more constant cutting engagement, which translates to improved surface finishes and longer tool life. Built to DIN 69880 standards for VDI toolholders, the assembly offers predictable performance in production environments where runout and chatter must be controlled. Design features that damp vibrations and accommodate bar profiles The holder’s slotted design permits controlled elastic deformation around the bar, which is the core mechanism for vibration damping. It is suitable for solid round boring bars, including those with a V-groove, and the clamping interface is sized for a 32 mm bar diameter. Because the body is Type B (not through-bored), the unit is optimised for standard clamping integrity rather than internal passage applications, ensuring secure retention during interrupted cuts and heavy engagement. Cooling adaptability and machining flexibility The design allows for both external and internal cooling, improving chip evacuation and tool life when machining challenging materials. Internal coolant use is conditional on the system design and the absence of a through-drilled shank in this Type B execution. The holder’s overall dimensions — 65 mm outer diameter and 142 mm overall length — provide a compact footprint while maintaining the rigidity needed for stable boring operations. Practical installation and dependable retention The toolholder is supplied with a retaining ring to prevent ejection into the turret, increasing workshop safety and uptime. The holder matches VDI40 interfaces and a 40 mm connection diameter where applicable, with a usable clamping length of 120 mm in its configuration. For routine maintenance, checking the clamping surfaces and retaining ring at regular intervals will sustain performance; replacement of worn components is straightforward and keeps machine availability high.
