Designed to ensure low cutting force, the TCL18-style chipbreaker is the latest addition to Tungaloy's TetraMini-Cut line of grooving inserts offering four cutting edges. TetraMini-Cut features a compact grooving insert with economical four cutting edges. Its innovative insert clamping ensures secure insert retention and high repeatability, promising machining accuracy and tool life predictability.

TCL18 ensures light cutting action and effective chip control when fed at low feed rates. The insert is coated in AH7025, a nano-multilayer PVD coating with high-aluminum content that provides hardness and adhesion to the grade for better process security during grooving operations.

The newest addition of TCL18 to the existing TCS18-, TCG18- and TCP18-style chipbreakers will further enhance the TetraMini-Cut insert family to meet the vast needs of grooving applications in general to miniature parts.
