Bosch Expert SDS-plus-7X Concrete Drill Bit 6 x 250 x 315 mm

This single-piece Bosch Expert SDS-plus-7X concrete drill bit (6 × 250 × 315 mm) is engineered for rotary hammer drilling in concrete and masonry. Made entirely from carbide, the bit head withstands the harsh impacts produced by power tools. It is rated for use in brick, concrete, hard concrete, natural stone, sandstone, and standard stone. It operates in hammer drilling mode to break up dense materials efficiently. At 6 mm in diameter, the bit creates correctly sized holes for common masonry anchors and fasteners. A total length of 315 mm provides access to recessed areas when boring through thick structural walls.

Equipment compatibility depends on the SDS-plus shank, which locks directly into matching rotary hammers without the need for a standard keyless chuck. This connection keeps a secure grip and prevents slipping during high-torque applications. With a working length of 250 mm, the bit sets the maximum depth that can be reached in a single pass. Four distinct cutting edges on the carbide tip fracture the substrate and stop the bit from jamming on hard aggregates. Operators must pair the accessory with a compatible rotary hammer, as it lacks the standard straight shank required for conventional drills. The integrated SDS design allows quick bit changes between tasks.

• 6 mm drill bit diameter creates appropriately sized holes for standard masonry fixings.
• 250 mm working length supports deep hole boring in single continuous passes.
• 315 mm overall length provides extended reach for penetrating thick structural blocks.
• Carbide construction resists wear from repeated high-impact strikes.
• Four cutting edges distribute drilling force to reduce jamming and maintain straight trajectories.
• SDS-plus shank provides secure bit retention and direct energy transfer from the power tool.
• Rated for hammer drilling in brick, sandstone, natural stone, and hard concrete.
