Bromsgrove-based Walter GB Ltd (
www.walter-tools.com) has announced the DB130 Advance as its smallest solid-carbide micro-drill for diameters from 0.1 to 1.45mm.
Walter says that this drill is suited to materials in the ISO P, M, K, N, S and O material groups (with oils or emulsions) for sectors that include general engineering, watch-making, automotive (components such as injector nozzles) and mould-and-die.
DB130 Advance drills are made using a homogeneous micro-grain carbide — a special grade that is said to allow optimum cutting-edge formation in high-precision applications.
