fgLathe reduction sleeve 20x20 to 12 mm – mounting heavy-duty boring bars
Looking for a way to use boring bars with a 12 mm shank in a standard lathe tool post? The 20x20 to 12 mm lathe reduction sleeve solves this problem – it converts a 20x20 mm slot into a holder for cylindrical tools with a diameter of 12 mm. One adapter provides access to an entire range of heavy-duty boring bars.
Why choose the 20x20 to 12 mm reduction sleeve?
- Machining holes from 14 mm – the thicker 12 mm boring bar shank ensures minimum overhang and maximum resistance to deflection
- Ready to work in a minute – simply slide the sleeve into the tool post and tighten the original screw
- Secure holding during rough turning – ideal for operations with large machining allowances
- One tool for multiple tasks – accommodates threading bars, form tools and tools with replaceable inserts
- Fits your lathe – the 20x20 mm standard is used in CNC and conventional machines from all manufacturers
Operators choose the 12 mm lathe sleeve when system rigidity and vibration-free operation matter. The lathe adapter is suitable for counterboring cylinders, boring sleeves and wherever slender boring bars fall short.
Invest in an adapter and work with tools that previously did not fit your tool post.
