Engineered for durability, these impact‑duty step bits feature a titanium aluminum nitride (TiAlN) coating that delivers up to five times longer life. The hex shank with Shockzone technology provides a robust connection, reducing early shank breakage. Dual‑spiral flutes and a rapid‑strike tip produce holes up to twice as fast as competing bits. A quad‑edge tip and 135° split point ensure precise starts and minimize heat buildup. The set includes eight bits ranging from 1/16" to 7/8" and a hard‑case for convenient storage.
