Bosch Expert SDS Max-8X Hammer Drill Bit 30 x 400 x 520 mm

The Bosch Expert SDS Max-8X Hammer Drill Bit 30 x 400 x 520 mm is a single-piece solid-carbide bit designed for heavy masonry work. The 30 mm cutting head bores into reinforced concrete, standard concrete, and solid stone. It needs a compatible rotary hammer to drive it through dense structural material. It is typically used to form precise clearances for large anchors, structural fixings, or service lines. Its carbide grade suits masonry applications where standard steel bits would wear quickly or fail to penetrate.

The SDS Max shank fits heavy rotary hammers directly, giving a secure connection that transfers impact force efficiently. The solid-carbide head resists heat and abrasion during long runs in masonry. This keeps the bit from deforming under sustained load. The body channels the hammer's energy straight to the cutting tip. Made in Germany, the bit holds its concentricity, keeping boreholes straight over an extended working life.

• 520 mm overall length gives the reach needed to bore through thick structural slabs.
• 400 mm working depth allows deep utility channels to be drilled in a single pass.
• 135° point angle engages the material immediately and stops the tip from wandering on smooth stone.
• Four cutting edges clear concrete dust quickly and reduce snagging on embedded steel reinforcement.
• SDS Max shank locks the bit firmly in the chuck without the need for an adaptor.
