It suits both left-hand and right-hand cutting orientations, making it adaptable across multiple turret positions. Machinists and CNC operators performing production parting on steel, cast iron, aluminum, and similar workpiece materials will find this blade at home in high-volume turning environments. Compatible inserts are from the 150.10-3 series family, and it pairs with 150.10-...-25 series tool blocks as specified by the manufacturer.
