56mm Reducer Bush Form 1 12mm Bore for Drill Rod Holder Form E, Hardened And Ground - TECWERK

Take advantage of a hardened and ground reduction bushing that secures a precise fit between drill rod and holder, featuring a Ø12 mm internal bore and Ø32 mm outer seat with a 56 mm clamping length for consistent tool location; order via Metav Werkzeuge or consult Metav specialists for compatibility advice.

Reducing bushing Form 1 – Ø12 mm bore, Ø32 mm outer, 56 mm clamping length | TECWERK

The Reducing bushing Form 1 is a hardened and ground sleeve for adapting 12 mm drill rods to holders with a 32 mm seat, engineered for use with Form E2 drill rod holders in clamping and tool-holding systems.

• Hardened and ground finish
• Fits Form E2 drill rod holders
• Bore Ø12 mm; outer Ø32 mm
• Clamping length 56 mm

Secure fit that reduces runout and improves repeatability

The reduction sleeve provides a compact adaptor which, when correctly seated, reduces axial and radial play and therefore contributes to improved clamping accuracy and repeatability in machining setups. The component is hardened and ground, which means the critical contact surfaces are prepared to resist wear and retain concentricity under cyclic loading. For workshop planners and production engineers this translates into fewer tool-change adjustments and steadier part tolerances, making process control more predictable.

Treatment and durability that lower maintenance intervals

Because the bushing is specified as hardened and ground, the wearing surfaces are optimised for longer service life and consistent performance. Such surface treatment reduces the need for frequent replacement and helps to maintain the original fit between drill rod and holder. In practice, this means less downtime for rework or replacement and a reduced total cost of ownership in comparison with untreated sleeves. The robust finish is particularly relevant where frequent tool changes or high spindle speeds place repeated stress on locating surfaces.

Direct compatibility with Form E2 systems for fast integration

The adaptor is designed specifically for use with Form E2 drill rod holders, ensuring immediate compatibility with corresponding holders and reducing the need for additional components. The specified dimensions — Ø12 mm internal bore, Ø32 mm outer seat and 56 mm clamping length — enable straightforward selection and installation in standardised tool-holding fixtures. Clear dimensional specifications simplify procurement decisions and minimise setup time when integrating into existing clamping assemblies.

Standardised components that streamline workflow

Using a standard reduction bushing simplifies inventory and standardises interfaces across multiple machines or fixtures. The component's clear dimensional data supports repeatable assembly procedures and consistent clamping behaviour across shifts and operators. As part of a systematic tooling strategy, such sleeves help to centralise spare-part lists and maintain process uniformity, which is especially valuable for small to medium workshops aiming to professionalise their production flow without complex retooling.

FAQ

What holders is this reduction bushing compatible with? The reducing bushing Form 1 is specified for use with Form E2 drill rod holders and will adapt a 12 mm drill rod to a 32 mm seat when matched to the correct holder.

Does the sleeve specify a base material or coating? The available data states the sleeve is hardened and ground but does not specify a base material or additional coating for the TECWERK reducing bushing (SKU 2000834214NW).

How does the clamping length affect tool stability? A clamping length of 56 mm increases the contact surface within the holder, which enhances axial support and contributes to improved stability during machining operations.

Is this component suitable for high-speed applications? The hardened and ground finish improves wear resistance and concentricity; however, final suitability for high-speed use should be confirmed against the machine and tool holder specifications for the intended application.
