Walter Solid Carbide Drill Is Supreme

2 September 2025

With the Drivox·tec™ Solid carbide drill DD170 Supreme, Walter has launched a new ‘holemaking icon’ to the market. Like its ‘iconic’ predecessor, the DC170 Supreme, the new DD170 Supreme has also been designed as a premium problem solver.

Perfect for holemaking in steel and cast iron, the Drivox·tec™ Solid carbide drill DD170 introduces technical improvements that are currently unique. The primary improvement is the new Krato·tec™® multi-layer coating. Walter has already introduced this in other drill families with remarkable success. This delivers tool life improvements in the region of 50% and more, depending upon the specific application.

The revised point geometry of the Solid carbide Drivox·tec™ DD170 Supreme holemaking series has an equally positive effect. Incorporating a larger clearance angle on the internal side than on the external side with a raised drill point, the DD170 Supreme improves the positioning accuracy. Furthermore, these geometry advances reduce axial forces and increase the hole quality, precision and machining performance.

The patented groove design has also been optimised. With a flatter entry point, the drill improves process stability, especially when machining soft materials like mild steel, as it minimises material sticking and improves swarf evacuation. In addition to optimising the cutting profile, Walter has also increased the number of flutes. With twelve grooves instead of eight, the DD170 Supreme can now be reground more frequently. This significantly increases both the service life and sustainability of the Solid carbide drill bit.

According to Walter, the new range demonstrates high process reliability in demanding applications such as cross holes and inclined exits. This is credit to the high wear protection of the Krato·tec® coating, which makes the DD170 Supreme the new benchmark for high-performance solid carbide drilling. The Tübingen-based company offers this premium new drill for the highest quantities and drilling volumes (without Pilot drilling up to 12XDc) with diameters from 3 to 20mm. Special tools and dimensions with shorter delivery times are also available via Walter Xpress.
