40mm Reducer Bush 16mm Bore, Hardened and Ground, L71mm - TECWERK

Combining hardened and ground construction with a 16 mm bore and a 71 mm clamping length, this TECWERK reduction sleeve delivers secure, repeatable clamping for E2 drill-bar applications; order through Metav Werkzeuge or ask our consultants for compatible holders and delivery options.

TECWERK reduction sleeve Form 2 — 16 mm bore, 40 mm outer diameter

TECWERK reduction sleeve Form 2 is a hardened, ground reducing sleeve for secure clamping of 16 mm drill bars in E2 drill-bar holders, optimised for repeatability and mechanical stability.

• Hardened and ground for long life
• 16 mm bore for standard drill shanks
• 40 mm outer diameter for stable clamping
• 71 mm clamping length for secure hold

Secure, repeatable clamping for production environments

The reduction sleeve is engineered to provide a precision fit between the drill bar and the holder, reducing runout and improving repeatability during machining. With a 16 mm bore and a 40 mm outer diameter, the component interfaces cleanly with Form 2 holders, while the 71 mm clamping length increases axial engagement to limit movement under load. These characteristics translate into fewer setup checks, faster changeovers and more consistent part quality on the shop floor.

Built for longevity and low maintenance

Manufactured hardened and ground, the sleeve resists wear and maintains concentricity over extended service intervals. This durability reduces tool-change frequency and prevents premature rework, supporting higher machine uptime and lower lifetime operating costs. The robust surface finish also eases inspection and seating, so replacement is straightforward when eventual wear occurs, supporting predictable maintenance planning.

Easy integration with existing clamping systems

Compatibility with E2 drill-bar holders simplifies retrofitting into established tool chains. The sleeve’s standardised dimensions make it suitable for mixed fleets where consistent clamping behaviour is required. For precise assembly, ensure the holder and drill bar faces are clean and lightly lubricated if recommended by the holder manufacturer; correct seating preserves the sleeve’s precision and ensures optimal torque transmission during drilling tasks.

FAQ

What sizes does the sleeve accept?
The TECWERK reduction sleeve Form 2 accepts a 16 mm nominal bore for drill bars and presents a 40 mm outer diameter for integration with Form 2 holders.

Is the sleeve suitable for intensive production use?
Yes, the hardened and ground finish of the TECWERK reduction sleeve supports long service life and stable clamping in continuous production environments.

How does the 71 mm clamping length benefit machining operations?
A 71 mm clamping length on the TECWERK sleeve increases axial engagement, which reduces movement under load and improves repeatability during drilling cycles.

Can this sleeve be used with other holder types?
The sleeve is specified for Form 2/E2 holders; compatibility with other systems requires verification of external diameter and seating geometry before installation.

How should the sleeve be installed for best results?
Ensure the holder and drill-bar faces are clean; seat the sleeve fully in the holder and confirm axial engagement to maintain the sleeve’s precision and repeatability.
