Bosch Expert SDS plus-7X Hammer Drill Bit Set, 5 Pieces (6/6/8/8/10 mm, SDS-plus)

The Bosch Expert SDS plus-7X Hammer Drill Bit Set, 5 Pieces (6/6/8/8/10 mm, SDS-plus) provides a collection of solid tungsten carbide accessories for heavy-duty construction tasks. This hammer drill bit set is engineered for drilling into dense structural masonry. Electric rotary hammers supply the impact force these bits need to work correctly. The tungsten carbide head keeps its hardness under continuous friction and high-impact strikes, allowing consistent penetration into tough materials for accurate anchor and clearance holes.

The bits use an SDS-plus shank for secure retention in compatible tool chucks. Each piece has a four-cutter full carbide head rather than a standard two-flute layout, which prevents the bit from catching or jamming when it strikes internal steel reinforcement. A welded connection joins the cutting head to the flute body. Sustained performance under heavy mechanical loads makes these bits suitable for repetitive structural installations.

• Duplicate 6 mm and 8 mm sizes plus a single 10 mm bit provide replacements for the most common anchor diameters.
• Rated for drilling into reinforced concrete, standard concrete, hard stone, soft stone, and concrete building blocks.
• 100 mm working length accommodates the deep clearance holes required for structural wall fasteners.
• 165 mm overall length provides sufficient reach while maintaining stability during high-speed rotation.
• Total kit weight of 406 g keeps the set portable for mobile site work.
