One connection suits a VDI system that directs coolant to the cutting edge via the insert's clamping finger, while the other is a threaded G 1/8 connector on the side leading to a hole on the other side of the insert to deliver coolant to the flank face. The two circuits cannot be used simultaneously.
The holder is of compact design and is offered with a 16 mm, 20 mm or 25 mm square shank. All sizes are available from stock for widths of cut of 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, 5.0 mm and 6.0 mm.
The shanks are made of high-strength steel, which ensures accurate location of the insert seat, leading to rigidity and hence long service life.
