8mm Reduction Bush Form 1 56mm Clamping Length, Hardened and Ground - TECWERK

Take advantage of a hardened, ground finish together with tight dimensional control — Ø 8 mm bore, Ø 32 mm outer diameter and 56 mm clamping length — for reliable concentricity and reduced runout in drill-bar applications; order the component directly via Metav Werkzeuge or consult our specialists for system integration.

TECWERK reducing bushing, Form 1 — 8 mm bore, 32 mm outer Ø

A TECWERK reducing bushing Form 1 designed to seat 8 mm shanks securely in 32 mm toolholders, optimised for drill-bar holders of Form E and engineered for repeatable mounting accuracy.

• Hardened and ground finish
• For drill-bar holders Form E
• Clamping length 56 mm
• Bore Ø 8 mm, outer Ø 32 mm

Consistent concentricity for precision machining

The combination of a hardened and ground surface with tight tolerances delivers a secure fit that preserves precision across repeated tool changes. With a bore of Ø 8 mm and an outer diameter of Ø 32 mm, the sleeve maintains axial alignment over its 56 mm clamping length, which reduces wobble at the spindle and lowers the risk of scrap. In practice, this means more dependable hole geometry and less time spent reworking parts when the component is used in a clamping system for drill bars.

Lower vibration, longer tool life and better finishes

By improving the interface between shank and holder, the reducer reduces vibration and minimises runout, which translates directly into extended tool life and improved surface finish. The mechanical stability provided by the sleeve helps cutters and drills operate closer to their optimal parameters, enabling higher effective feed rates or more consistent cycle times — a clear efficiency advantage for production environments where throughput matters most.

Clear compatibility and straightforward installation

The sleeve is specified for holders of Form E, ensuring reliable integration with compatible drill-bar systems. Installation is straightforward: the component slides into the toolholder and provides a direct, repeatable seating for the shank. The design supports conventional clamping workflows and is suitable for retrofit into existing fixtures that accept a 32 mm outer diameter insert, simplifying upgrade paths without the need for elaborate adapters.

Robust construction reduces downtime and maintenance

Manufactured to industrial clamping standards, the component is built to resist wear under frequent use. The hardened and ground treatment preserves concentricity over time, reducing maintenance intervals and the need for frequent regrinding or replacement. For workshops aiming to consolidate suppliers, the sleeve represents a small inventory item that delivers measurable uptime benefits when applied consistently across compatible holders.

FAQ

What shank diameter does the sleeve accept?
The sleeve is made for an Ø 8 mm shank; the internal bore is specified to secure that diameter reliably for drilling applications.

Is the reducing bushing hardened?
Yes — the component is hardened and ground, providing wear resistance and stable concentricity under repeated use.

Which holder types is it compatible with?
The sleeve is intended for drill-bar holders of Form E and fits holders that accept an outer diameter of Ø 32 mm.

What is the clamping length and why does it matter?
The clamping length is 56 mm; this length increases the contact surface for the shank, enhancing stability and reducing the chance of movement under load.

Can this sleeve improve tool life?
When used correctly, the reducer reduces runout and vibration, which contributes to longer tool life and more consistent machining results with the TECWERK reducer (SKU 2000834212NW).
