Product description
The cutting edges of the MEGA-Speed-Drill-Iron are unequally split. In addition, the drill has three guide chamfers. This prevents vibrations and reduces friction. The highly polished flutes guarantee optimum chip flow. The cutting geometry, which is specially adapted to cast iron, makes it possible to produce holes with up to 30% higher feed rates compared to conventional drills.
