Tritan-Drill-Steel – The New Drilling Standard

When MAPAL brought its Tritan-Drill to market, the company defined a new standard in drilling. At EMO 2017 in Hanover, the tool manufacturer presented its latest addition to the range, the Tritan-Drill-Steel for machining steel. With the Tritan-Drill-Steel, the material can be machined faster and more efficiently compared to drills with two cutting edges. 

Previously drills with two cutting edges and a flat chisel edge were used for drilling steel and this meant users had to struggle with concentricity. Additionally, the 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 by using three individual chisel edge segments that reliably centre the Tritan-Drill-Steel for improved performance and reliability. 

The robustness of the Tritan-Drill-Steel is credit to the completely new design of the main cutting edge that is different to the Tritan-Drill-Uni that is applied for universal applications. The very stable cutting edges reduce the mechanical loads whilst the coating is also specially adapted for the machining of steel. In this way, wear-resistance during steel machining is significantly increased when compared to the Tritan-Drill-Uni. Fast and reliable chip removal is also achieved credit to the shape of the main cutting edge that ensures short, tightly rolled chips and ground chip flutes, which further extends tool life. 

Like the Tritan-Drill-Uni for universal use, the Tritan-Drill-Steel has also proven itself in difficult drilling situations such as 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-Steel is available with an internal coolant shank form HA with a diameter range of 4 to 20mm in the lengths of 3xD, 5xD, 8xD and 12xD.
