71mm Reduction Sleeve 32mm Bore 40mm Outer Diameter Hardened And Ground - TECWERK

Achieve secure, concentric clamping and longer tool life thanks to the hardened and ground finish together with the precise 32 mm bore and 71 mm clamping length; order the part directly via Metav Werkzeuge or ask our consultants for selection support.

Reduction bushing Form 2 – TECWERK, 32 mm bore, 71 mm clamping length

A Reduction bushing Form 2 designed for accurate reduction of holder diameters and reliable seating in drill rod holders, suitable for retrofit work and small-series production.

• Hardened and ground for durability
• 32 mm inner bore for precise seating
• 40 mm outer diameter for standard holders
• 71 mm clamping length for stable fixation

Consistent concentricity for reduced runout and improved part quality

The hardened and ground finish provides a precision mating surface that reduces radial play and vibration during machining. By combining a true 32 mm inner bore with a controlled outer form, the sleeve promotes consistent centring of the tool shank and lowers runout. This results in fewer rejects and more predictable machining results, supporting higher first-pass yield and reduced rework.

Straightforward compatibility with Form E2 holders for easy retrofitting

Designed to fit drill rod holders of Form E2, the bushing converts a standard 40 mm holder to accept a 32 mm shank without complex adapters. The clearly defined 40 mm outer diameter and standardised geometry allow rapid installation into existing clamping systems, which minimises fixture changes and keeps set-up times short. Retrofit tasks and small-batch jobs benefit from the simple, deterministic interface.

Robust clamping length that improves stability and tool life

With a 71 mm effective clamping length, the sleeve increases contact area and axial support for the tool shank, reducing bending stress under load. The extended engagement improves heat dissipation and lowers the risk of micro-movements that accelerate wear. For workshops seeking steadier cutting performance and less frequent replacement cycles, this combination of finish and length delivers tangible productivity gains.

FAQ

What are the exact dimensions of the sleeve?
The TECWERK reduction bushing Form 2 (SKU 2000834228NW) has an inner bore of 32 mm, an outer diameter of 40 mm and a clamping length of 71 mm.

Which holder type is this bushing intended for?
This sleeve is made for use with drill rod holders specified as Form E2, providing a standardised interface for retrofit and replacement tasks.

Is the surface treatment suitable for workshop use under load?
Yes — the component is hardened and ground, offering wear resistance and a precise seating surface for stable clamping during machining.

How does the clamping length affect machining stability?
The 71 mm engagement increases axial support and reduces bending of the tool shank, which improves stability, lowers runout and contributes to longer tool life with fewer interruptions.

Is the base material specified for the bushing?
No material designation is provided in the available data; the specification states only the hardened and ground treatment for the sleeve
