Highly rigid and lightweight head prevents vibration for better surface finishes.

• Three different lengths of carbide shank boring bars available.
• A wide range of inserts.

Features

Using computer simulation a highly rigid & lightweight head configuration has been designed to reduce chatter and improve the vibration damping properties.

Note)
The above data was found when using a FSCLP1816R-09S type holder, under the following
conditions; l/d=5, Depth of cut=0.5mm,Feed=0.05mm/rev.

Carbide Shank Type

The carbide shank type Dimple Bar uses through coolant holes.

A stable coolant supply to the cutting point is possible even when boring deep holes.
