Aalen, Germany – The Tritan-Drill, the three-fluted drill from MAPAL, achieves more bores, a longer tool life, and lower machining costs compared with its twin-fluted companion. The Tritan-Drill makes it possible to machine with a significantly higher feed rate. In both standard and special designs, it combines process reliability and high performance. It is a universal drill for a wide range of materials and provides rounder bores and reduced burr formation. These results are achieved due in part to the innovative geometry that gives rise to optimum chip removal and a low cutting pressure. The Tritan-Drill is also convincing for long-chipping workpiece materials due to its special chip formation.
In difficult drilling situations such as cross bores or inclined bore entrance, the Tritan-Drill has proved to be effective:
45% more bores when compared with a twin-fluted drill, are possible when machining a cylinder head made of GJL 250. Previously a twin-fluted step drill was used for machining the 15mm and 16mm diameters. 1,800 bores were machined with a cutting speed of 100m/min and a feed rate of 0.2mm/rev. With the three-fluted Tritan step drill, not only the cutting speed and feed rate could be increased to 130m/min and 0.34mm/rev. The tool life of the drill is also significantly longer with 2,600 bores.
The Tritan-Drill for machining steels, cast materials, and non-ferrous metals is in the standard program and thus available from stock. The drill is available with a diameter range of 5mm to 20mm and in designs up to 8xD.
