Makita Metal Drill Bit HSS-CO

The Makita HSS‑Co Metal Drill Bit is a professional‑grade accessory made from high‑speed steel alloyed with cobalt (typically 5%), designed for maximum durability and performance when drilling into tough and hardened metals. The cobalt content increases heat resistance, reduces wear, and ensures longer service life compared to standard HSS‑R, HSS‑G, or HSS‑TiN bits. Its 135° split‑point tip provides self‑centering accuracy, minimizing wandering and enabling efficient drilling even in high‑strength materials.
