Bosch SDS-plus-5 Hammer Drill Bit 8 x 250/310 mm

The Bosch SDS-plus-5 Hammer Drill Bit 8 x 250/310 mm is a single-piece accessory designed for heavy hammer drilling applications. Constructed with a carbide tip, this masonry bit provides stable cutting performance in dense building materials. It is rated for use on concrete, lime and sand bricks, solid brick, concrete building blocks, and hard stone. An integrated ActiveCentering tip helps prevent the bit from wandering at the start of hole creation. The two-flute cutting section uses AWB brazing and hardening technology, which limits vibration and improves durability during sustained use. This design ensures accurate starts and maintains structural integrity when working in tough stone.

Measuring 8 mm in diameter, the bit has a total length of 310 mm and a working length of 250 mm. This extended reach accommodates deep anchor installation and standard through-hole drilling in thick masonry walls. The base uses a standard SDS-plus shank, ensuring direct compatibility with matching rotary hammers without adapters. A visible wear mark is machined into the flute to help users gauge hole diameter accurately, which matters when installing tolerance-sensitive fixings. Manufactured in Germany, this 100 g accessory delivers consistent results for professional and advanced DIY renovation work. The SDS system provides secure power transfer from the chuck to the cutting head under high impact loads.
