The Bosch Expert 2 608 900 195 drill bit set contains seven carbide-tipped bits engineered for reliable drilling into concrete and natural stone. Sizes span 5.0 mm to 12.0 mm, providing a practical range for anchor holes, through-holes and light demolition starter holes. The bits are supplied in a compact, robust storage case suitable for transport and workshop organization. The set is designed for use with standard SDS-plus rotary hammers and compatible hammer drills, delivering consistent drilling performance for both professional tradespeople and home DIY users.

Advantages

Bits feature carbide tips and optimized flute geometry to improve dust removal and reduce heat buildup during hammer drilling. The set covers common diameters needed for fixing anchors and through-holes in masonry, reducing the need to change tools frequently. The durable plastic case protects the bits from damage and keeps them organized, while precision-ground tips provide stable centering and reduced walking at drill start.

How to use

Select the appropriate bit diameter for the required hole, secure the drill bit in the hammer drill or rotary hammer according to the tool manufacturer's instructions, and set the tool to the hammer drilling mode if available. Start drilling at low speed to establish the hole, then apply steady pressure and maintain perpendicular alignment to the work surface. Periodically withdraw the bit to clear dust from the hole and allow the bit to cool when drilling multiple holes or extended depths.

Recommendations

Use appropriate personal protective equipment including eye protection, dust mask and hearing protection. For reinforced concrete, consider using a smaller pilot hole first and increase diameter gradually. Store the bits dry in the supplied case to prevent corrosion and check the tip condition regularly; replace bits that are chipped or excessively worn to maintain drilling quality.
