Solid carbide drill features a new innovative thinner web

Walter has introduced the new DC166 Supreme solid carbide drill. It has been specially developed for machining aluminum and other ISO N workpiece group materials, such as copper, brass and bronze.

The drill with internal coolant features optimized point geometry creating a “coolant pocket” that provides more space for coolant flow resulting in better chip evacuation. In addition, the patent-pending web design results in sharper cutting action that prevents built-up edge and enhances chip removal.

All the key surface on the drill—flutes, land, and flank faces are polished. Polishing reduces friction and prevents adhesion (built up edge) when drilling highly gummy material.

The carbide drill can be used with emulsion, oil and minimum quantity lubrication (MQL).

The standard DC166 Supreme is for drilling holes up to 5xD in accordance with the DIN 6537 long standard. The drill is available from 0.118 to 0.472 in. (3 to 12 mm) in diameter.

Walter also enables the tool to be ordered as a special for drilling up to 30xD in a diameter range from 0.118 to 0.787 in. (3 to 20 mm) via the Walter Xpress Service.
