Sealed Coolant	Summary
Sealed through-the-tool coolant is offered on all standard KM tooling and	KM coupling offers a very rigid joint with a high degree of repeatability while
clamping units. The coolant is sealed using O-rings in both the cutting units and	maintaining a compact envelope. This permits a high degree of versatility without
clamping units. This feature ensures that coolant is directed as close as possible	sacrificing cutting performance.

to the cutting edge while preventing contaminants from entering the clamping mechanism. Standard Viton® O-rings are utilized on KM.

Accuracy and repeatability of the coupling are shown in the table below. Accuracy is measured over a gage insert in different cutting units
