25-piece HSS-CO metal drill bit set, 113 mm Milwaukee MLWK-4932493868

The MILWAUKEE metal drill bit set is manufactured from high-speed steel (HSS) alloyed with 5% cobalt, designed for professional applications involving hard materials and high temperatures. Built in accordance with DIN 338 standards, these drill bits deliver superior precision, strength, and durability under heavy-duty use.

The 135 split point tip ensures fast and accurate centering without the need for prior punching, reducing the risk of walking at startup. The optimized flute geometry provides efficient chip removal, while the cobalt content significantly improves heat resistance during drilling.

This set is ideal for machining high-alloy steels, stainless steel, and heat-resistant materials, ensuring consistent performance even in the most demanding working conditions.
