Solid carbide drill

Walter has introduced the DC118 Supreme solid carbide drill for challenging applications.

These “180° drills” provide high rigidity against deflection, enhanced centering accuracy, and have four margins with corner chamfers, which improve guidance in challenging applications.

Walter says 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 low. The protective corner chamfer on the cutting edges protects against rapid wear, which increases tool life compared to drills without a protective chamfer.

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 fine-grained substrate with superior toughness. Additionally, the WJ30ET coating provides 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 which are used in universal applications.

Practical applications, in addition to flat bottoms, inclined entry or round surfaces, also include operations involving thin walls, counter-boring or chain drilling. Walter offers the drill in the highest performance class with a diameter of 3–20 mm (including popular inch sizes) up to 2 × D as standard or as a special tool up to 5 × D via Walter Xpress.
