Mapal Faster, better, stronger and a longer tool life
Germany – The three-fluted Tritan drill from Mapal is said to feature a longer tool life and lower machining costs compared with its twin-fluted companion and can machine at a higher feed rate.
Good for a wide range of materials, it provides rounder bores and reduced burr formation as its geometry provides optimum chip removal and low cutting pressure, the company says.
In cross bores or inclined bore entrances, the Tritan step drill has a cutting speed and feed rate of up to 130 m/min and 0.34 mm/rev. respectively – and, a tool life of 2,600 bores.
Also, ideal for difficult drilling situations like the machining of a VA-rail, the part of the Tritan drill that is exposed to strong mechanical loads at high temperatures is manufactured from heat-resistant steel with an austenitic structure. The alloy ensures high strength at operating temperatures of up to 1050°C, Mapal adds.
Here the Tritan drill achieves a tool life of 63 m or 4,200 bores – all at a high feed rate. The drill is available in diameters of 5 mm to 20 mm as well in designs of up to 8 x D.
