The Garant MasterSteel SlotMachine from the Hoffmann Group is a solid carbide roughing end mill which achieves high feed rates when slot milling from solid steel. The knuckle form profile produces extremely compact swarf. Because of this, the Hoffmann Group was able to construct the milling cutter with five cutting edges, delivering higher process efficiency with a constant feed rate per tooth. The knuckle form profile means that the cutting pressure is lower and that higher feed rates can be obtained with a constant load. Due to the compact chips and the lower cutting forces, this end mill is particularly suitable for milling deep slots and for machining delicate components. The tool can achieve a feed rate of 0.1 mm per tooth at cutting depths of 2×D. It is available with cutter diameters ranging from 4 to 20 mm.

Based on its unusual geometry, the MasterSteel SlotMachine produces very short, fine and tightly-rolled chips that are easily cleared by the flat chipbreaker recesses. Directional chip discharge increases process reliability, while the extremely sturdy core diameter stabilizes the tool.

The tool enables plunge angles of up to 10 degrees. The honed cutting edge design minimizes the risk of breakaways. The ultra-fine grain substrate greatly increases the resistance to breakage, while the enhanced coating also optimizes the wear characteristics and reduces the rate of heat input. The unequal spacing ensures smooth cutting action.
