With the new Drion·tec D-Spade D5142 exchangeable-tip drill, Walter is launching the world’s first drill of its kind with a double-sided indexable insert. The special feature is the flank face of the first cutting edge. This serves as a support surface for the second cutting edge that doubles the service life of the exchangeable tip and reduces the costs per metre of drilling.

Designed for cost efficiency, the drill comes in diameters from 12 to 32 mm and cutting lengths from 3xD to 8xD. Four lands and the self-centring point geometry ensure high precision and smooth surface quality of the hole. Furthermore, exact centring, straightness and diameter tolerance are guaranteed.

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 high levels of 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 with conventional drills on the market, reports Walter. The company is therefore positioning the Drion·tec D-Spade D5142 as the new standard for both cost-conscious and sustainable hole-making. The drill is particularly suitable for mass manufacturers machining steel and cast-iron materials, such as in the automotive, energy or rail industries.
