Achieve clean, burr-free holes, excellent chip evacuation, and vibration-free rotary drilling with authentic NIQUA SUPER Q® Twist Drill Bits Series “58PM”. Manufactured from premium hardened tool steel with genuine Swiss Made precision, this high-performance twist drill series is engineered specifically for fine jewelry manufacturing, micro-drilling, and precision mechanical operations.
Featuring an optimized spiral flute geometry, the Series “58PM” delivers smooth cutting action and rapid chip flow when drilling soft precious metals such as gold and silver, as well as copper, brass, and related alloys. The hardened tool steel structure provides high wear resistance and stability across elevated rotational speeds. Fitted with a standardized 2.35 mm (3/32”) shank, it integrates seamlessly into standard jewelry micromotors, flexible shaft handpieces, and bench rotary systems across diameters from 0.50 mm (58PM-005) to 2.30 mm (58PM-023).
