Bosch X-LINE 70-piece drill bit set provides a comprehensive assortment of bits for drilling in metal, wood and masonry. The set groups a range of diameters and types to cover common household and professional tasks such as installing fixtures, drilling pilot holes and surface mounting. Bits are stored in a compact, labeled case that keeps components organized and accessible on job sites and in workshops.

Each bit is intended to deliver consistent drilling results across the specified materials: high-speed steel bits for metal, brad-point and twist bits for wood, and carbide-tipped or masonry bits for concrete and brick. The case is designed for secure storage and quick selection of the required diameter, supporting efficient workflow and transport.

How to use

Select a drill bit appropriate for the material and desired hole diameter, then insert it into the drill chuck and tighten securely. For metal, use steady speed and light to moderate pressure to avoid overheating; for wood, use brad-point or wood bits at higher speed for clean entry and reduced splintering; for masonry, use hammer or rotary hammer mode with masonry bits and apply firm, consistent pressure. Start with a pilot hole if precise positioning is required and wear appropriate personal protective equipment such as safety glasses and gloves.

Usage recommendations

Match bit type to material and adjust drill speed and pressure accordingly. Replace worn bits to maintain hole quality and use a lubricant when drilling metal to extend bit life. Store bits in the supplied case to prevent loss and damage.
