BCK

MICRO BORING HEAD

Applications: Used for precision internal machining. It supports both boring and back-boring operations, ideal for mold making, mechanical parts, and high-accuracy hole finishing.

Features

Pre-balanced design ensures stable machining accuracy, suitable for boring diameters Ø20~Ø203 mm.
BCK boring heads feature coolant design and support both boring and back-boring operations, three insert holders sizes available for each head.
Each boring head comes with a insert holder (BCK H#-1), other sizes must be purchased separately.
Insert must be ordered separately.
