Walter has introduced the Drion·tec E‑Peak D5150, a new replaceable‑head drill designed to deliver what the company describes as ‘the peak of productivity’ in high‑performance drilling applications. The tool has been engineered to achieve exceptionally high feed rates and metal‑removal rates, offering a significant reduction in cost per hole compared to conventional systems.
A key element of the D5150’s design is its ability to drill without the need for pilot holes, eliminating an entire machining stage and the associated cycle time. Walter has also developed the DS50 replaceable head so that it can be exchanged directly inside the machine without the use of screws. This straightforward changeover process reduces set‑up time and helps maintain uninterrupted production.
The drill body itself has been strengthened with reinforced radial contact points and inclined axial contact surfaces that efficiently absorb cutting forces. Walter says this robust construction supports stable, reliable performance even under demanding conditions. The tool also features a three‑dimensional flute geometry with a large axis angle, combined with a high‑performance through‑coolant system. Together, these elements promote dependable chip evacuation, including when working with inclined or curved entry surfaces.
Process reliability has been a major focus of the D5150’s development. The patented cutting point design incorporates axial pull‑out protection to ensure the head remains secure during retraction, retaining its release torque even after repeated head changes. The low‑vibration DS50 heads contribute further to accuracy, providing excellent centring and hole quality thanks to free grinding and an optimised point angle.
Walter has equipped the interchangeable heads with a universal M‑geometry and offers two cutting grades, WPP35 and WMS35. This allows the D5150 to operate effectively across a broad spectrum of cutting data in ISO material groups P, M and S, as well as K, N and H. According to the company, this level of versatility makes the drill suitable for an extensive range of applications, reducing the need for multiple dedicated tools.
The initial launch covers diameters from 9 to 17.99mm, including nominal inch sizes, with drilling depths of 3xD, 5xD and 8xD. Walter notes that several head dimensions can be used with the same drill body, helping to limit inventory requirements and lower purchasing costs.
