Walter Launches New Solid Carbide Drill

Walter has introduced the DC118 Supreme solid carbide drill. These 180° drills are said to differ from standard solid carbide drills by providing high rigidity against deflection, superior centering accuracy and four margins with corner chamfers, which enable guidance in challenging applications.

The 180°-point angle makes the DC118 Supreme ideal for plunging into inclined or round surfaces because the drill is guided quickly on the margins and centered accurately. At the same time, burr formation remains extremely low. The protective corner chamfer on the cutting edges protects against rapid wear, which increases tool life compared to drills without a protective chamfer. The rigidity of the drill is a third feature which sets it apart from the competition.

Initially designed for 180° pilot drilling of deep bores on crankshafts, the current DC118 Supreme drill versions are now suitable for universal application with all materials and components. The drill has a unique fine-grained substrate with toughness. Additionally, the WJ30ET coating provides universal protection against tool wear in all material classes including steel, stainless steel, cast iron, non-ferrous material and super alloys (ISO Groups P, M, K, N and S). WJ30ET is the same coating that is used on Walter’s DC160 drills. Practical applications, in addition to flat bottoms, inclined entry or round surfaces, also include operations involving thin walls, counter-boring or chain drilling. In these applications, the DC118 Supreme excels with long tool life and a high degree of precision and process reliability. Walter offers the drill with a diameter of 3-20 mm (as well as popular inch sizes) up to 2 × D as standard or as a special tool up to 5 × D via Walter Xpress.
