Tip for depth

Spherical cutting edges provide a high level of stability and thus ensure a long tool life and high level of productivity. The point angles were selected so that the deep drills always start the cut with the chisel in the pilot bore. The standard range available from stock includes length ratios of 15xD to 40xD and the diameter range from 3 mm to 16 mm, with the long designs up to 9 mm. Adapted pilot drills are available for difficult drilling conditions.

With the MEGA-Deep-Drill-Steel, deep drilling is possible without pecking cycles at very high feed rates. The tools are suitable both for use with internal cooling and for minimum quantity lubrication, which has a positive effect on the tool life in steel machining. Field tests have shown that the new deep drills from MAPAL meet the highest requirements for tool life and performance even with demanding materials. Compared to its predecessors, up to 50 percent higher feed rates can be achieved.
