Star-M Japanese 601 Precision Drill Bit 5.5mm

• Designed specifically for soft materials like wood, leather and plastics that can otherwise be problematic to drill, these wonderfully innovative Japanese drill bits produce exceptionally clean, crisp holes.
• Hooked spurs clear any remaining waste from the perimiter of the cut, these are followed by semicircular wings that incise a little deeper to part the waste from the surrounding material. A curved cutting edge then planes the waste out and sends it up the flutes.

For plastics use a low speed setting, for fibrous materials use your highest speed setting, and in both cases introduce the bit to the material gradually.
