MAPAL redefines deep drilling in aluminium

It is based on a newly developed overall concept comprising cutting edge geometry, cooling and cutting material. The new geometry includes a wide range of applications, from wrought alloys through to cast alloys with high silicon content. The straight main cutting edge ensures smooth, low-vibration processes and reduces macroscopic flaws and burr formation, particularly in demanding applications, such as cross bores or angled exits. Double point thinning and optimised chip flutes ensure improved chip removal. The adapted core diameter profile also increases tool stability, thereby enhancing process reliability at large drilling depths.

Another key factor for process reliability is precise tool guidance over the entire drilling depth. Four guide margins stabilise the process even with cross bores or angled exits, ensuring reliable machining conditions even at high feed rates.
 

The new second-generation MEGA-Deep-Drill-Alu from MAPAL offers large drilling depths, high process reliability and flexible adaptation to different aluminium materials, all in one integrated tool concept. Extensive trials with end-users confirm the great potential of the new generation. For example, the MEGA-Deep-Drill-Alu achieved feeds of up to 0.4 mm per revolution and tool lives of up to 3.2 kilometres.

The new deep drill was particularly developed for applications in the automotive industry and general machining. It is available in length versions from 15×D to 40×D and, depending on the respective length, in diameters from 3 to 16 mm.
