More productive holemaking in next to no time

One of the most important reasons for special tools is to increase productivity by integrating multiple machining steps in one tool. The DC165 Advance solid carbide drill, which can be designed as a special tool alongside the standard range, offers a wide variety of options for this. The drill's design with straight flutes makes it particularly suited for production as a special tool because, unlike conventional twist drills, no warping distortion at the dimensional transitions. As a step drill, it offers an extensive range of diameters, from intermediate steps through to large diameters. The polished flutes on the DC165 Advance improve chip removal and minimise build-up on the cutting edge. This is particularly advantageous when machining aluminium, which is the drill's primary application in addition to machining cast iron workpieces.

Four lands help the DC165 Advance ensure excellent guidance – and therefore extremely precise roundness and straightness of the bore, as well as high surface quality. Users benefit from company-specific services alongside the high drill quality that they will generally be familiar with. These include the option of having the tool reground up to three times in the Walter Reconditioning Centres around the world and also by the Walter Xpress service. This is because Walter also offers the DC165 drill as a special product up to 12 × D with a delivery time of just two weeks. In addition the typically listed application areas in general mechanical engineering, hydraulic manufacturers and automotive suppliers are mentioned in particular.
