Kennametal’s HPS solid carbide drills are constructed of the company’s Beyond KN15 carbide, making them suitable for aluminum machining applications including holemaking. Designed as an alternative to PCD drills for high-precision applications, the tools are said to enable demanding production schedules while reducing costs.
The drill's carbide grade features a highly polished surface to reduce friction on flutes, margins and cutting edges. The grade, combined with the enlarged spiral flute design, eases chip evacuation in minimum quantity lubrication processes. The 135-degree drill point is designed for improved centering capabilities and feeds. The HPS drills are available in sizes ranging from 3 to 20 mm in diameter and lengths of 3×D and 5×D (through-coolant). Inch, metric, fraction and tapping sizes are also available.
