Premium tool manufacturer Walter is presenting its X·treme Evo Plus drill from the DC180 Supreme product family – in 8 × Dc for the first time. The drill with through coolant and four lands is distinguished by extraordinarily good guidance in the drill hole. It consequently enables high precision – even for greater drilling depths and interrupted cuts – and increases process reliability. The same applies to the polished flutes which optimise chip evacuation (e.g. for stainless materials), as well as the straight cutting edges which likewise offer an increased level of reliability and stability. The Krato·tec multi-layer coating, specially developed for drilling and reaming tools, achieves the highest cutting speeds, and increases tool life by about 50% when compared to other products on the market. With the 8 × Dc version, the AlTiN layer is designed as a tip coating in Walter's own WJ30EY grade for the first time.
The DC180 Supreme drill can be used universally for a multitude of applications in all ISO materials from the P, M, K, N, S and H groups. In addition to the standard dimensions (dia. 3–20mm), Walter also offers the solid carbide drill as a special tool with intermediate dimensions and as a step drill. With the Walter Xpress service, users also benefit from a reduced delivery time (max. three weeks). Due to its productivity and wear resistance, the DC180 Supreme can optimize the costs of complex ISO M and S machining operations in the long term, for example in the aviation industry or with components for the automotive industry. The Krato·tec coating boasts additional advantages in terms of tool life and process reliability.
