World First With Two Cutting Edges

The Walter exchangeable-tip drill Drion·tec D-Spade D5142

With the new Drion·tec D-Spade D5142 exchangeable-tip drill, Walter AG is launching the world's first drill of its kind with a double-sided indexable insert. The special feature: The Flank face of the first cutting edge serves as a support surface for the second - which doubles the service life of the exchangeable tip and significantly reduces the costs per metre of drilling. Designed for maximum cost efficiency, the holemaking drill is designed for Ø 12 to 32 mm and lengths from 3 to 8 × D(c) .Four lands and the Self-centring point geometry ensure high precision and Surface quality of the hole: with exact centring, straightness and diameter tolerance.

Ground and polished Chip clearance spaces optimise Chip evacuation and increase process reliability. Six Coolant outlets ensure Precision cooling on the Cross cutting edge, Main cutting edge and Circumference on both teeth. The combination of fine-grain substrate and the gold-coloured HiPIMS coating of the DS42 indexable insert enables very good Wear resistance and easy wear detection. The symmetrical design of the double-use exchangeable tips not only doubles Tool life, but also reduces the amount of carbide used per cutting edge by 45% compared to conventional drills on the market. Walter is therefore positioning the Drion·tec D-Spade D5142 as the new standard for both cost-conscious and sustainable holemaking - particularly suitable for mass producers with steel and cast iron materials, for example in the Automotive industry, the energy sector or the rail vehicle industry.
