Iscar’s TigerV-CW heavy-duty grooving inserts are designed with a chipformer to ensure better tool security, chip control and ejection in difficult grooving operations on carbon and high-alloy steel, even at slow speeds.
The cup-shaped chipformer is pressed into the insert’s top face behind the cutting edge to deform chips. It breaks chips into short, open segments to optimize expulsion. This is especially useful for making deep grooves in workpieces, which commonly increase the risk of sudden tool failure, the company says, as surface cutting speed declines with radius and the deepening groove makes chip expulsion more uncertain.
The inserts are available in 14- and 17-mm widths with center-screw clamping to fit into a V-lock toolholder with a flat-top surface. The flat-top design ensures unobstructed chip flow, even from the bottom of a deep groove, the company says.
