The Walter X·treme Evo Plus DC180 Supreme solid-carbide drill maximizes productivity due to Krato·tec coating technology.

Solid-Carbide Drill for Productivity and Reliability

July 27, 2023
Designed with internal coolant and customized coating, it’s effective for drilling steels, stainless steels, cast irons, non-ferrous metals, heat-resistant super alloys, and hard materials.

WALTER USA, LLC is launching a new tool in the DC180 Supreme product range – the X treme Evo Plus drill – designed to boost productivity and process reliability. The solid-carbide drill with internal coolant is effective 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 part of the Supreme series, the drill is designed for long tool life, 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.

Also, it 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. Another benefit 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, 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.
