20mm Reduction Bushing Form 2, Bore 20mm AD 25mm Clamping Length 46mm - TECWERK

A hardened, ground reducer sleeve delivers a precise interface between a 20 mm tool shank and a 25 mm toolholder while the 46 mm clamping length ensures stable support under load. Benefit from improved repeatability and reduced runout for consistent machining results. Order the reducer sleeve directly via Metav Werkzeuge or ask our consultants for tailored application advice.

Reducer sleeve Form 2 – 20 mm bore, 25 mm outer diameter (TECWERK)

A Reducer sleeve Form 2 engineered to adapt a 20 mm shank to a 25 mm holder, providing secure clamping in machining and tooling applications

• Hardened and ground finish for wear resistance
• Adapts 20 mm shanks to 25 mm holders
• 46 mm clamping length for stable support
• Compatible with Form E 2 toolholders

Precision fit and secure clamping for reliable setups

The hardened and ground surface of the reducer sleeve guarantees a tight, repeatable fit between the tool shank and holder. With a 20 mm bore matched to a 25 mm outer diameter, the component minimises radial play and contributes directly to reduced runout. Designed for use with Form E 2 toolholders, this bushing improves concentricity and helps maintain cutting accuracy over multiple tool changes, which is critical for consistent part quality.

Stable support through optimised clamping length

A 46 mm clamping length provides a broad contact area that enhances axial and radial stability during machining. The extended engagement reduces bending loads on the tool shank and spreads clamping forces, which helps to lower vibration and tool deflection. Engineers and technicians benefit from fewer setup adjustments and longer tool life because the increased support transfers load evenly across the interface.

Simple integration into existing toolholder systems

The reducer sleeve fits directly into standard toolholders conforming to the specified form, allowing easy replacement of worn adaptors without redesigning the spindle or holder stack. The element functions as a compact adaptor that restores compatibility between differing shank and holder diameters, reducing the need for multiple custom holders and simplifying tool inventory management. This pragmatic approach lowers downtime and streamlines workshop logistics.

Consistent machining performance and operational confidence

By combining a precise bore finish with heat treatment and grinding, the reducer sleeve delivers predictable behaviour across repeated cycles. The TECWERK reducer sleeve supports consistent setups and measurable improvements in process stability, helping to reduce scrap rates and rework. For production environments where repeatability is paramount, this bushing is a straightforward way to enhance throughput and maintain dimensional tolerances.

FAQ

What is the primary function of the reducer sleeve?
The reducer sleeve provides a precise mechanical interface that adapts a 20 mm shank to a 25 mm toolholder, improving clamping security and reducing runout for repeatable machining.

Which toolholders are compatible with this sleeve?
Compatibility is specified for Form E 2 toolholders; the TECWERK reducer sleeve (SKU 2000834206NW) is designed to seat directly into holders built to that form.

How does the 46 mm clamping length affect stability?
A 46 mm clamping length increases contact area between shank and holder, distributing forces more evenly, reducing deflection and vibration, and therefore improving tool life and surface finish.

Is this sleeve suitable for heavy-duty or high-wear applications?
The hardened and ground finish enhances wear resistance and dimensional stability, making the sleeve suitable for demanding machining cycles where consistent performance is required.
