Productivity at the highest level

2 February 2026

With the Drion·tec® E-Peak D5150, Walter is introducing a new replaceable head drill that represents the ‘peak of productivity’ when drilling. According to Walter, the D5150 enables extremely high feed rates and metal removal rates, which significantly reduces the cost per hole.

The Drion·tec® E-Peak D5150 eradicates the need for drilling pilot holes, and the DS50 replaceable head can be exchanged directly in the machine without screws. Both of these features reduce machining and set-up times, significantly improving productivity. The Drion·tec® E-Peak D5150 drill body has reinforced radial contact points and inclined axial contact surfaces that absorb any cutting forces that occur.

The three-dimensional flute geometry with a large axis angle combines with a powerful and efficient through-coolant delivery system that enables efficient, reliable chip evacuation even with inclined or curved workpiece surfaces.

In addition to high productivity, the Walter replaceable head drill impresses with its high process reliability. This comes from the stable, patented cutting point design with axial pull-out protection. This ensures risk-free retracting and retains its release torque even after numerous head changes. The low-vibration DS50 interchangeable heads guarantee unparalleled precision and centring with impeccable hole quality thanks to the free grinding and point angle.

Credit to its universal M geometry and the two cutting grades (WPP35 and WMS35), the D5150 can be used with a vast range of cutting data in all ISO material groups P, M and S, as well as in K, N and H. This extensive selection of materials and machining parameters makes the Drion·tec® E-Peak D5150 the drill of choice.

Walter is initially launching the D5150 with diameters from 9 to 17.99mm, including nominal inch diameters, in drilling depths of 3XD, 5XD and 8XD. Several head dimensions can be used in the same drill body, which also reduces storage and purchasing costs.
