7 Piece 847 Combination Tapping Drill Bit Set

The Wera 7 Piece 847 Combination Tapping Drill Bit Set is a professional HSS drill and tap solution designed for mobile repair and assembly work. This comprehensive kit combines drilling and tapping operations in a single tool, eliminating the need to change between separate drill bits and taps during threaded hole creation. Manufactured from high-speed steel with finely-tuned material elasticity, these combination bits deliver excellent durability and precise performance. The hexagonal shaft design ensures optimal power transfer when used with power screwdrivers or electric drills, whilst the ¼" drive configuration conforms to DIN ISO 1173-D 6.3 standards for universal compatibility. The set includes the innovative Rapidaptor quick-release chuck, enabling swift bit changes on site without interrupting workflow. Each combination bit features superior centring properties for accurate hole placement, efficient chip removal to prevent binding, and minimal tilt risk for consistent results. The kit arrives in a robust plastic storage box that protects the bits during transport and keeps them organised between jobs. Ideal for electricians, plumbers, and general contractors working across multiple sites, this set covers the most commonly used sizes for creating threaded holes in metal components, junction boxes, and structural steelwork.
