TECWERK reduction sleeve Form 1 — bore Ø8 mm, OD 40 mm

A TECWERK reduction sleeve Form 1 engineered to secure Ø8 mm drill shanks in Form E 2 holders, hardened and ground for consistent concentricity and reliable clamping in industrial and workshop environments

• Hardened and ground for precision
• For drill shank holders Form E 2
• Clamping length 71 mm for stable hold
• Bore Ø8 mm, outer diameter 40 mm

Consistent clamping for repeatable results

The reduction sleeve provides a compact, precise interface between the drill shank and the holder. Thanks to the hardened and ground finish, the sleeve reduces micro-movement under load, which supports repeatable bore quality and longer tool life. Where repeatability across batches matters, the combination of exact inner diameter and defined clamping length ensures a stable seating surface that minimises runout and vibration during drilling.

Compact dimensions that improve stability

With a bore of 8 mm, an outer diameter of 40 mm and a clamping length of 71 mm, the sleeve balances compactness with sufficient engagement length to resist bending moments in typical toolholding setups. The relatively long engagement compared with the small bore produces a secure hold for short shank tools, delivering better concentricity than ad hoc adaptations. These dimensions make it suitable for confined spindle spaces while still providing robust clamping performance.

Designed for integration in Form E 2 systems

Compatibility is a core advantage: the sleeve is produced for use with Form E 2 drill shank holders, enabling straightforward integration into existing clamping systems without modification. The standardised form factor simplifies inventory and reduces changeover time on the shop floor. Where machine-tool interfaces are standardised, this approach reduces setup complexity and supports efficient process repeatability.

Practical benefits for production and workshops

Beyond immediate technical gains, the sleeve supports economic operation by lowering scrap rates and reducing rework. The ground surface helps ensure uniform contact and easy inspection for wear, while the robust construction means predictable service intervals. For toolrooms and maintenance teams seeking compact, reliable toolholding accessories, this reduction sleeve offers a focused solution that complements precision tooling inventories

FAQ

What are the exact dimensions of the reduction sleeve?
The TECWERK reduction sleeve Form 1 (SKU 2000834222NW) has a bore of 8 mm, an outer diameter of 40 mm and a clamping length of 71 mm.

Is the sleeve compatible with Form E 2 holders?
Yes — the component is specified for use with drill shank holders Form E 2 and is manufactured to provide a precise fit for that interface.

What advantage does the hardened and ground finish provide?
The hardened and ground surface increases wear resistance and improves seating accuracy, which reduces runout and supports repeatable hole quality in production.

How is the sleeve installed into the holder?
The sleeve is inserted into the corresponding Form E 2 holder and secured according to the holder’s clamping procedure, providing a concentric locating surface for the drill shank.

Which work environments benefit most from this sleeve?
Toolrooms, small-batch production and industrial workshops that require stable clamping of Ø8 mm shank tools will gain the most from the sleeve’s precision and compact form
