Bosch Expert SDS-plus-7X Hammer Drill Bit 30 x 400 / 450 mm Carbide 4-Cutter

The Bosch Expert SDS-plus-7X Hammer Drill Bit 30 × 450 mm is a one-piece carbide hammer drill bit designed for heavy-duty masonry work. It is rated specifically for drilling into hard mineral building materials, including reinforced concrete and solid stone. During operation, the percussive action of the rotary hammer breaks up dense material while the bit clears debris from the hole. Used in dedicated hammer drilling mode, the bit handles demanding construction, installation, and renovation work. The flute design supports consistent material removal when boring deep holes for heavy structural anchors.

Measuring 30 mm in diameter, the bit provides substantial width for heavy installations. An overall length of 450 mm gives an effective working depth of up to 400 mm for long-reach requirements. The cutting head features a four-cutter tip configuration designed to handle intensive tasks without jamming against dense aggregates. Power is transferred directly through the SDS-plus shank, which anchors the bit securely in compatible rotary hammers. Finished in standard grey, the bit integrates directly into professional setups and supports rapid, tool-free bit changes on site.

• 30 mm cutting diameter produces correctly sized holes for large structural anchors and pipe penetrations.
• 450 mm total length provides an effective 400 mm working depth for thick concrete walls.
• Four-cutter tip geometry reduces the risk of jamming when striking reinforced steel.
• SDS-plus connection ensures a secure, slip-free fit without separate chuck adapters.
• Solid carbide construction withstands high impact forces during continuous percussive drilling.
• Rated for hammer drilling only, in masonry, concrete, and hard stone.
