Walter introduces the Drion∙tec® D-Spade D5142 replaceable tip drill and DS42 double-sided insert.

The Walter replaceable tip drill is the world’s first with two cutting edges. 

Walter 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 drill’s DS42 replaceable tip is made of the WPP25 grade, which features a fine-grained carbide substrate and an aluminum titanium nitride (AlTiN) coating deposited via high power impulse magnetron sputtering (HiPIMS). The gold-colored top layer provides the best wear detection.

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).

The drill produces precise holes due to four ground margins on the cutting edge in addition to Walter’s face grinding process for creating the best insert seating and centering characteristics. Polished chip flutes ensure quick and reliable chip removal. Two radial clamping screws enable a high level of process stability.

The drilling depths for the Drion∙tec® D-Spade D5142 replaceable tip drill are 3 and 5 × Dc. The drill can create holes from 12 to 25.70 mm, including inch-nominal sizes.
