* CBH boring head loaded opposite direction can process boring machining.
* Each boring head has three different size cartridges for different boring range.
* Formachining blind hole with insert angle 3°can avoid the impact to the end surface. * Cartridge could be mounted in opposite direction for back boring. * Higher rigidity and better working performance are provided by close connection between cartridge and boring head. * All DCK-CBH micro boring tools have internal cooling design which improve surface roughness and inserts tool life.
