Walter has released the new X·treme Evo Plus drill, a new tool in the DC180 Supreme product range.
The new solid carbide drill features internal coolant and is optimized for drilling steels, stainless steels, cast irons, non-ferrous metals, heat-resistant super alloys and hard materials (ISO P, M, K, N, S and H workpiece groups). As with other drills in the Supreme category, the drill is designed for extended tool life and high process parameters and productivity.
Users can achieve maximum productivity with the DC180 drill due to the Krato·tec aluminum titanium nitride (AlTiN) multi-layer coating technology, which was specifically developed for drills and reamers. The drill features a straight cutting edge to ensure process reliability and stability. The drill has a 140°-point angle and is suitable for holemaking with emulsion, oil or minimum quantity lubrication (MQL).
When compared to competing drills, the DC180 Supreme has a tool life that is about 50% longer, Walter says. An additional benefit for the DC180 drill is universal application at the highest cutting speeds. The drill is suitable for high production volume applications with a large number of holes, such as in the automotive industry. Other areas of use include the aerospace and energy industries, mold and die making, and general mechanical engineering.
The WJ30EZ-grade drill is comprised of the K30F fine-grained carbide substrate and available in diameters from 0.118 to 0.787 in. (3 to 20 mm). The DC180 Supreme in dimensions of 3 × Dc is in accordance with the DIN 6537 short standard, and the DC180 Supreme in dimensions of 5 × Dc is in accordance with the DIN 6537 long standard. Walter Xpress specials with short delivery times (maximum of three weeks) can be ordered for drilling up to 5 × Dc, as well as in step drill styles. The tool shank is in accordance with the DIN 6535 HA standard, and the shank end is in accordance with the DIN 6909 standard.
