New MAPAL Tritan-Drill-Steel

New MAPAL Tritan-Drill-Steel

Last year MAPAL defined a new standard in drilling with the Tritan-Drill. Drills with three cutting edges will now be gradually added to the programme. At EMO 2017 in Hanover, the tool manufacturer is presenting a version that is specially adapted for machining steel. With Tritan-Drill-Steel, the material can be machined significantly more cost-effectively compared with drills with two cutting edges. Among other things, this is achieved thanks to the significantly higher feed values.

Previously drills with two cutting edges with a flat chisel edge were usedfor drilling steel. Users hat to struggle with the fact that the required roundness and cylinder shape of the bore was not guaranteed due to an oscillating movement along the chisel edge. In addition the cutting edges and the guiding chamfers were subjected to high mechanical loads. Oscillating movements are prevented with the new drill using three individual chisel edge segments that reliably centre the Tritan-Drill-Steel.

The robustness of the Tritan-Drill-Steelis due to the completely newly designed main cutting edge design that is different to the Tritan-Drill-Uni for universal use. The resulting very stable cutting edges reduce the mechanical loads. The coating is also specially adapted for the machining of steel. In this way, wear-resistance during steel machining is significantly increased compared with Tritan-Drill-Uni. The result of this is very long tool lives. Fast and reliable chip removal is also achieved by the shape of the main cutting edge that ensures short, tightly rolled chips and ground chip flutes.

Like the Tritan-Drill-Uni for universal use, the Tritan-Drill-Steelhas also proven itself in difficult drilling situations, for example for cross bores or inclined bore entrances. For example, inclined boring up to 12° with a length of 5xD can be realised without problem.

The Tritan-Drill-Steelwill be presented at EMO 2017 in Hanover. It will be available with internal cooling and shank form HA at a diameter range of 4-20 mm in the lengths 3xD, 5xD, 8xD and 12xD.
