Walter (Greer, SC) premieres the Drion∙tec D-Spade D5142 replaceable tip drill that accepts the symmetrical DS42 double-sided insert, which provides twice as many cutting edges as other replaceable tip drills on the market. This innovation significantly reduces the cost per cutting edge during drilling applications.
The drill features three coolant outlets per tooth—on the main cutting edge, chisel edge and circumference—for precise maximum cooling. Because the drill is double effective, a total of six coolant outlets work to cool the insert at the cutting zone.
With its 120° point, the drill is capable of an inclined entry up to 10° and an inclined exit up to 20°. This capability is higher than the typical 5° inclined entry and exit limits for other drills in its class. The drill also performs effectively in cross-hole applications, with four margins engaged to support the drilling operation and impart a fine surface finish.
The tool is suitable for drilling blind holes and through holes from solid workpieces, as well as for stack, or laminate, drilling. The primary application is for drilling steel (ISO P material group), and the secondary applications are for cast iron and non-ferrous materials (ISO K and N material groups).
