The Forstner Highspeed from Heller drills perfect, precise, and smooth blind holes as well as edge drillings, and is also suitable for angled drilling. The well-thought-out drill geometry and innovative cutting edges enable extremely fast drilling progress. The induction-hardened main cutting edges are equipped with a patented wave grind. The result is minimal friction, low wear, and precise chip removal for accurate drilling. Since both cutting edges engage simultaneously, smooth hole surfaces are created, and the cutting proceeds quickly and precisely.
