Horn USA Inc. has combined the features of various toolholders into its 224 grooving system. The new toolholder features two coolant connections, which are made either via a transfer on the contact surface or via a threaded connector on the side. The internal coolant supply is fed directly to the insert via the clamping finger or directly to the flank face via a hole.

Horn offers the toolholder in a compact design as a square shank of dimensions 0.63" × 0.63" (16 mm × 16 mm), 0.787" × 0.787" (20 mm × 20 mm) or 0.984" × 0.984" (25 mm × 25 mm). All toolholder sizes are available from stock for widths of cut of 0.079" (2.0 mm), 0.098" (2.5 mm), 0.118" (3.0 mm), 0.157" (4.0 mm), 0.197" (5.0 mm) and 0.236" (6.0 mm). The tool shanks are made of high-strength steel, which provides high precision of the insert seat and a long service life of the system.
