The market for micro drills keeps growing. This is largely driven by the increasing desire for ever-smaller technology as well as intricate components. Premium manufacturers such as Walter are responding to this trend by constantly expanding their range of cutting tools.

The latest additions to the Walter range are the Walter DB133 and DB131 Supreme solid carbide drills. When used in combination with the DB131 Supreme fully coated micro pilot drill, the DB133 Supreme deep-hole drill in particular delivers impressive surface quality, tool life and process reliability. Specialist flute geometries are designed to optimise chip breaking to ensure that chips are kept short and therefore easy to remove.

Suitable for a wide range of materials and universal application, another integral factor in the solid carbide drill's performance is the point angle and diameter tolerances (p7/h7). Both drills are tailored to suit one another so that the pilot drill can deliver the best possible results for the deep-hole drill. The newly developed Walter processes, such as those for rounding the main cutting edges, increase the precision of the drills. This is particularly important in mould and die making, for instance, where fine tempering channels often have to be inserted close to the surface.

After all, lateral wandering, which is far more commonplace with HSS drills than with solid carbide drills can result in extensive damage to the component. Furthermore, the drills perform around six times faster than a gun drill. Both the DB131 Supreme and the DB133 Supreme are suitable for reconditioning and re-grinding. The solid carbide drills are available in diameters starting at 2 mm. Walter can also offer intermediate sizes for delivery within a number of weeks via its Walter Xpress service.
