Tungaloy expands its TetraForce-Cut, a four-edged indexable grooving tool series, to include the new TCL27-style chipbreaker.

TetraForce-Cut's indexable insert boasts cost-effective, four cutting edges with a grooving depth of up to 6.4mm. The toolholder has a unique insert clamping structure that ensures high repeatability and accuracy for maximum insert stability and tool life.

The new TCL27-style chipbreaker features a deep dimple profile on the rake face, providing low cutting force and effective chip control during difficult grooving operations. The geometry is available in a universal AH725 grade, which improves machining efficiency and stability.

Combined with existing TCS27- and TCM27-style chipbreakers, the comprehensive offering of TetraForce-Cut grooving inserts will meet a wide range of grooving needs in general lathes and Swiss-type machines.
