Lathe reduction sleeve Ø20 mm to 6 mm – universal SHB adapter
Lathe reduction sleeve Ø20 mm to 6 mm is an intermediate component between the lathe tool post and a boring bar with a smaller shank diameter. The Varel Ø20 mm to 6 mm lathe sleeve is suitable for both series production and one-off jobs requiring frequent tooling changes.
Why choose the SHB Ø20 to 6 mm sleeve?
- Common Ø6 mm internal diameter — matches the shanks of most boring bars for holes from 8 to 16 mm
- Three clamping screw system — evenly distributed pressure prevents tool rotation and pullout
- Ø20 mm outside diameter with a flat at 19 mm — fits typical tool posts used in Polish machine shops
- One-piece construction without play — minimizes machining errors caused by unstable clamping
- Repeated setup changes — threaded screw holes remain durable even with daily use
The Ø20 mm to 6 mm lathe adapter expands workstation capabilities without the expense of replacing the entire tool post. The Ø6 mm diameter is among the most frequently chosen by lathe operators because it covers a wide range of boring bars for typical workshop tasks. The Ø20 mm to 6 mm lathe sleeve works with CNC and conventional machines, providing identical clamping geometry regardless of lathe type.
