Bosch 7-Piece MultiConstruction Drill Bit Set with Titanium Nitride Coating, Hex Shank, 3-8 mm 2607017197

Titanium nitride coating on high-speed steel delivers up to three times longer life in metal, while the hex shank ensures slip-free power transfer in cordless drills and impact drivers. This 7-piece set covers diameters from 3 mm to 8 mm, ready for masonry, metal, wood, plastic, and tiles.

Overview

The Bosch MultiConstruction drill bit set combines a robust HSS-TiN body with a precision-ground tip geometry that works across common jobsite materials. A 1/4" hex shank fits standard quick-change chucks, eliminating bit slippage during high-torque drilling. Right-hand rotation suits all standard drills and impact drivers.

What stands out

• TiN coating reduces friction and heat build-up, extending bit life in metal and hardwood.
• Multi-material tip design drills cleanly into masonry, metal, wood, plastic, and tiles without changing bits.
• Hex shank provides positive engagement in keyless and impact chucks, preventing spin-out.
• Seven diameters (3, 4, 5, 5.5, 6, 7, 8 mm) cover most pilot and clearance hole needs.
• Compact plastic case keeps bits organized and protected on the move.
