AK9043 covers the middle micro-drilling band with 10 carbide bits from 0.4 to 1.3 mm. Every intermediate tenth is present, giving you a closely spaced choice when the intended hole is too small for broad jumps between diameters. Carbide is the cutting material of the bits themselves, and at these diameters the work is pinning, wire runs and locating holes rather than heavy stock removal. Sizes included: 0.4, 0.5, 0.6 and 0.7 mm; 0.8, 0.9, 1.0 and 1.1 mm; 1.2 and 1.3 mm. All ten bits share one shank thickness, keeping the holding end consistent across the set. Stored upright in labelled slots inside a transparent hard plastic case. Show more
