Reduction sleeve Form 1 – bore Ø 12 mm, outer Ø 40 mm (TECWERK)

Reduction sleeve Form 1 for adapting smaller drill bars to larger holders in workshop and industrial clamping systems

• Hardened and ground finish
• Bore Ø 12 mm for precise fit
• Outer Ø 40 mm nominal diameter
• Clamping length 71 mm for stable support
• Compatible with Form E2 drill shank holders

Reliable clamping through hardened and ground surfaces

The primary benefit of a hardened and ground reduction sleeve is consistent precision during machining operations. Hardening increases surface wear resistance while grinding produces a true, low‑tolerance bore; together they reduce radial runout and prevent premature tool wear. This results in fewer tool changes and improved component quality. The finish is particularly relevant where concentricity matters, such as reaming, drilling and light milling tasks, delivering measurable gains in process repeatability and tool life.

Clear dimensions for seamless compatibility and retrofitting

With a Ø 12 mm internal bore, a Ø 40 mm external diameter and a 71 mm clamping length, the sleeve offers defined mechanical interfaces for secure clamping. The geometry is designed for use with standard drill shank holders of Form E2, enabling straightforward adaptation of smaller tooling into larger holders without bespoke adapters. For procurement and logistics, the clear dimensional specification simplifies inventory choices and reduces the number of specialised holders required on the shop floor.

Practical use and workshop advantages

The reduction sleeve is manufactured for robust everyday use in both light industrial and professional workshop environments, providing stable tool support along the clamped length. Installation is mechanical and does not require special assembly aids; once seated in the holder, the sleeve secures the tool shank to maintain concentricity under load. The combination of durability and precise fit lowers scrap rates and contributes to shorter setup times, supporting a smoother production flow and better overall equipment effectiveness.
