Product Description

The SANDVIK COROMANT 5856751 is a right-hand indexable grooving toolholder from the CoroCut 1-2 series, designed for both internal and external grooving operations on CNC lathes and turning centers. The toolholder features a 0.5 inch square shank (0.5 inch width by 0.5 inch height) and accepts N123F2 series inserts secured by a top-clamp holding method. With a maximum depth of cut of 0.59 inches (15 mm) and a maximum workpiece diameter of 1.18 inches, this toolholder is built for precision grooving in tight-tolerance applications. Toolholder material is steel, and the overall length is 5 inches.

This toolholder is suited for shop-floor machinists and toolroom technicians running internal or external grooving operations on small-diameter workpieces. The CoroCut 1-2 style F123 body is a widely used platform in production turning environments where reliable insert seating and repeatable groove geometry are required. It is classified as a multi-use tool, making it adaptable across a range of grooving and parting applications within its size range. No coolant-through capability is present on this model.
