QTD STEEL-PYRAMID

If steel is to be machined under unstable machining conditions, for example thin walls, or large diameters are to be machined in steel, MAPAL can offer a new insert with pyramid tip for the QTD indexable insert drill. Thanks to the innovative point thinning and the geometry of the chisel edge, the tool centres itself and therefore ensures safe bore entrance even in difficult machining situations. A low burr bore exit is also ensured thanks to a flat tip angle from 160˚.

The coating of the new indexable insert is specially adapted to machine steel. The tough substrate and geometry of the indexable insert also ensure long tool life and that it is highly resistant to wear. Once the indexable insert has reached the end of its tool life, users can replace it quickly, easily and with a high level of precision. Since the cost-intensive carbide is limited to the indexable insert, the use of the QTD indexable insert drill is also particularly economical.
