In difficult drilling situations such as cross bores or inclined bore entrance, the Tritan-Drill has proved to be effective. Many practical examples also speak for themselves:
Significantly more bores, remarkably 45 percent, 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 15 and 16 mm diameters. 1,800 bores were machined with a cutting speed of 100 m/min and a feed rate of 0.2 mm/rev. With the three-fluted Tritan step drill, not only the cutting speed and feed rate could be increased to 130 m/min and 0.34 mm/rev. The tool life of the drill is also significantly longer with 2,600 bores.
Another example of the versatile range of applications of the Tritan-Drill is the machining of a VA-rail. This part that is exposed to strong mechanical loads at high temperatures is manufactured from heat-resistant steel with an austenitic structure. The alloy ensures a high strength at operating temperatures up to 1050 °C and prevents embrittlement but is difficult to machine. The Tritan-Drill is also suitable for this challenge. Compared with a twin-fluted step drill that has a tool life of 48 metres, corresponding to 3,200 bores, the Tritan-Drill achieves a tool life of 63 metres, or 4,200 bores. And all this at a high feed rate.
The reliable machining of a turbocharger made of heat-resistant cast steel is another successful application of the Tritan-Drill in practice. Previously with a twin-fluted drill with a 8.3 mm diameter, a maximum of 60 parts could be machined. The Tritan-Drill manages 140 parts. This means that productivity is 130 percent higher.
The Tritan-Drill for machining steels, cast materials and non-ferrous metals is in the standard programme and thus available from stock. The drill is available with a diameter range of 5 to 20 mm as well in designs up to 8xD. The Tritan-Drill as a special tool is also available at short notice.
