Product description

The MEGA-180°-Drill-Alu has a 180° point angle and a special bevel to produce a flat bore base. Due to its four-bevel geometry and the resulting very good guidance in the bore, the MEGA-180°-Drill-Alu achieves optimum roundness and surfaces in the bores. In addition, polished chip flutes ensure optimum chip transport. The MEGA-180°-Drill-Alu is also suitable for drilling and piloting on inclined surfaces of up to 45°. Due to the flat tip, the radial forces are reduced compared to conventional 140° drill tips.
