With the DB130 Advance solid carbide drill for diameters between 0.1 and 1.45 mm, Walter launches the smallest carbide micro twist drill in its product range (for larger diameters of 0.5 mm and above, the Walter DB133 Supreme solid carbide drill can be used).
The drill fulfils the dimensions according to DIN 1899. It stands out especially thanks to its high precision, process reliability and universal usability. The drill is made using a very homogeneous micrograin carbide – a special grade that enables optimum cutting edge formation. It therefore fulfils very high requirements for precision and tool quality.
Due to the large standard range, the DB130 Advance solid carbide drill can be used universally in a wide range of applications: With oil and emulsions, in the ISO material groups P, M, K, N, S, and O. The range of applications of the solid carbide micro drill includes general mechanical engineering, the watchmaking and automotive industries (e.g. injector nozzles), the food industry (e.g. hole slices for meat or cheese production), as well as mould and die making.
