ABSTRACT:
A metal cutting system with a tool holder, a shim, an insert with a top depression, a top piece and a clamp. A rake face cooling channel for fluid delivery is formed between the top piece and the depression in the insert. A primary discharge slot at the end of the rake face cooling channel delivers fluid from below the cutting edge of the insert. A second cooling channel for delivery of fluid to the flank face is formed between the insert and the shim or is formed between the shim and the tool holder with a portion of the cooling channel passing through the shim.
