World first with two cutting edges

This serves as a support surface for the second cutting edge that doubles the service life of the exchangeable tip and significantly reduces the costs per metre of drilling.

Designed for maximum cost efficiency, the drill is designed for diameters from 12 to 32mm and cutting lengths from 3 to 8XD. Four lands and the self-centring point geometry ensure high precision and impeccable surface quality of the hole. Furthermore, exact centring, straightness and unsurpassed 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 excellent 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. This is particularly suitable for mass manufacturers machining steel and cast iron materials, such as in the automotive industry, the energy sector or the rail industry.
