Reducing bushing Form 1 (6 mm bore, 40 mm OD) – TECWERK

A Reducing bushing Form 1 for drill shank holders, hardened and ground to deliver secure clamping and repeatable tool concentricity in production and workshop environments

• Hardened and precision ground
• 6 mm bore for small‑diameter tooling
• 40 mm outer diameter for Form 1 holders
• 71 mm clamping length for stable grip

Precision fit for repeatable set‑ups

The sleeve delivers a precise interface between small‑diameter tooling and larger holders. With a 6 mm bore and 40 mm outer diameter, the component provides concentricity that minimises run‑out and enhances machining accuracy. The geometry reduces repositioning time during tool changes and supports predictable tolerances in serial production. This makes the device a practical choice for workshops requiring consistent results from every set‑up.

Durable treatment for long service life

Manufactured hardened and ground, the bushing resists wear and maintains internal tolerances over extended use. The surface finish lowers friction during insertion and removal, which reduces fretting and preserves the bore dimension. Such treatment translates into fewer replacements and less downtime, supporting a more economical tool management strategy while maintaining machining quality.

Stability in the clamping zone improves productivity

A 71 mm clamping length provides a secure contact area that helps to absorb cutting forces and to prevent axial movement under load. The extended engagement length complements the outer diameter for a robust connection in the holder. For operations that demand stable tool presentation—drilling, reaming or light finishing—the component reduces vibration and contributes to improved surface quality and tool life.

Easy integration and practical handling

Designed for use with the Form E2 drill shank holder family, the adaptor simplifies integration into existing clamping systems without complex rework. The straightforward geometry and known dimensions support quick verification during tool pre‑set and spare‑part management. For application questions or dimension checks, technical advice is available to ensure the sleeve matches the intended holder and tool combination.

FAQ

Is this bushing compatible with Form E2 holders?
Yes. The TECWERK reducing bushing Form 1 is designed for use with drill shank holders of the Form E2 family and matches the specified outer diameter for a secure fit.

What do "hardened and ground" mean for service life?
Hardened and ground indicates the sleeve has undergone heat treatment and precision grinding, which increases wear resistance and maintains bore accuracy during repetitive insertion and machining cycles.

How is the bushing installed in the holder?
The sleeve is pressed or slid into the host holder until fully seated; axial positioning is determined by the holder's stop. Ensure cleanliness of contact surfaces and correct seating to achieve intended concentricity.

Can the sleeve be used with other holder types?
Compatibility with other holders depends on matching the outer diameter and clamping interface; the component will work with alternative systems only when the OD and locating features correspond to the host holder.

What is the SKU for ordering and spare‑part tracking?
The SKU for this TECWERK reducing bushing Form 1 is 2000834221NW
