Walter has launched the new DC183 Supreme solid carbide drill.

The DC183 Supreme has three cutting edges for improved hole roundness and high productivity. Walter has introduced the DC183 Supreme with three cutting edges to achieve high machining volume. The drill has internal coolant channels and can be used with emulsion, oil or minimum quantity lubrication (MQL).

The drill is coated with Walter’s new Krato·tec wear-resistant coating to achieve maximum productivity when holemaking. The fracture-resistant aluminum titanium nitride (AlTiN) multiple-layer coating technology was developed specifically for soled carbide drilling tools. The textured top layer has a high aluminum content for heat, wear and oxidation resistance, while the graded transition layer provides balanced residual stresses, and the base layer prevents cracks from forming in the coating.

The coating’s benefits include maximum cost-efficiency due to the Krato·tec multiple-layer coating, high productivity and reliability thanks to the new layer architecture, protection against wear and adhesion when drilling at high cutting speeds, and superior performance when drilling numerous different workpiece materials. In company tests, the Krato·tec coating showed up to a 50 per cent increase in tool life compared to competing coating technologies, Walter says.

The primary applications for the DC183 Supreme are machining steel, cast iron and non-ferrous materials (ISO P, K and N). Secondary applications are super alloys and stainless-steel materials (ISO S and M). The main targeted areas of use are automotive, aviation and energy industries, mould and die making, and general mechanical engineering.

The diameter dimensions for the standard DC183 Supreme are from 0.118 in. to 0.630 in. (3 to 16 mm). The standard drill can produce holes 5 × Dc in accordance with the DIN 6537 long standard and holes 8 × Dc in accordance with the Walter standard. The diameter dimensions for the Walter Xpress drill are from 0.118 in. to 0.787 in. (3 to 20 mm). The Walter Xpress is for drilling holes up to 30 × Dc. The drill is available in two grades: WJ30EX, the AlTiN multiple-layer coating, and WJ30EY comprised of the K30F substrate and the AlTiN tip coating.

Walter states that its “Supreme” classification indicates “the highest level of technology and performance available.”
