About our Boring Bar Sleeves:
We are proud to supply our range of Boring Bar Sleeves. These are supplied hardened and ground.
These are designed to allow for the reduction of large diameter End mill/Sidelock holders to accept smaller boring bars or other straight shank tooling of the internal diameter noted in the table above.
Smaller sizes are Form B that have screws to secure the boring bars being used. Larger sizes are Form A that have slots in the sleeves to allow the End Mill holder screws to secure the boring bars.
