Drilling problems solved with Mapal Tritan
Featuring a design with three cutting edges, solid carbide drills in the Tritan range from Mapal have been developed for use in challenging applications such as through-boring, inclined entry drilling and the dry machining of aluminium.
Special lead geometry is said to provide low cutting pressure and excellent chip removal. According to Mapal, Tritan drills allow up to twice the feed rate to be used in comparison with conventional drills.
The drills have point thinning features machined into the chip space so that chips experience minimal friction as they are discharged into the drill flutes. As a result, both cutting pressure and edge temperature are low, ensuring that burring is kept to a minimum even when dry-drilling aluminium. In addition, the drills have a self-centring chisel edge that bites into the workpiece on first contact and holds accurate position, says Mapal.
