Wolf 17-Piece TCT TiN Coated Drill Bit Set, Wood Brick Concrete & Steel Drilling

The Wolf 17-Piece Professional Drill Bit Set uses TCT (Tungsten Carbide Tipped) construction for durability and a lasting cutting edge, with a TiN (Titanium Nitride) coating on each bit to reduce friction and improve wear resistance over repeated use. The set covers diameters from 3mm to 12mm, giving enough range for most drilling jobs without needing to buy bits individually.

A 1/4" hex shank means the bits work with both keyed or keyless chucks and hex chucks found on impact drivers, and the hexagonal shape reduces slipping in the chuck for more precise drilling. The bits are suited to wood, brick, concrete, steel, ceramic, porcelain, and glass, covering most materials encountered across DIY and trade work. The set is backed by a 10-year warranty and comes housed in a heavy-duty fabric case for storage and transport.
