To provide users with enhanced versatility, the properties of the various tool holders in Horn's 229 grooving system have been combined into one design having two connections for internal transfer of coolant. It may be routed through the holder via a threaded port on the side to the insert clamping finger. Alternatively, it can be directed at the insert flank face via a different hole. Either enables high performance internal, external and face grooving, as well as parting off.

Horn offers the compact, square shank tool holder in sizes 16 mm x 16 mm, 20 mm x 20 mm and 25 mm x 25 mm. All holders are available from stock for cutting widths of 3.0 mm, 4.0 mm, 5.0 mm, 6.0 mm and 8.0 mm. Grooving depth is independent of the size of the tool holder. The shanks are made of high-strength steel, which ensures high precision of the insert seat and long service life of the grooving system.
