The Bosch EXPERT SDS-plus-7X hammer drill bit, Ø 10 mm, 50 pieces (working length 100 mm), is intended for professional and demanding home use when drilling in concrete and natural stone. As part of the EXPERT series, it is distinguished by its innovative design and the experience of the Bosch brand in the field of drilling tools. The package contains 50 drill bits, which is suitable for larger projects, frequent work or sharing between users in the workshop.

In practice, this drill bit enables precise and efficient drilling into harder materials using the SDS-plus system, which is a widespread standard for use with hammer drills. The combination of a diameter of 10 mm and a working length of 100 mm meets the most common needs in assembly, electrical and construction work, where a stable and reliable hole is required. The overall length of the drill bit allows drilling deep enough for most anchoring and fastening applications in masonry or concrete walls.

Key product features

The quadruple spiral geometry and solid carbide head provide efficient dust extraction and reduce the possibility of jamming when drilling, which means better stability and longer drill life. This increases drilling accuracy and reduces the need for frequent tool changes, which is especially important in serial or long-term work.

The SDS-plus clamping system ensures quick and safe bit changes, with less energy loss during impact transmission — essential when using more powerful hammer drills, where a combination of power and control is important. The 50-piece pack is ideal for use in workshops, construction companies or for ongoing projects where consistent hole quality and fewer delays in replacing worn bits are important.

The Bosch EXPERT SDS-plus-7X drill bit combines a robust design optimized for use in concrete and stone with practical details such as the appropriate length and quick clamping system. This enables professional results in various types of construction, installation and assembly work, where tool reliability is key to an efficient workflow.

It is important to know

This is a specialized kit, so before purchasing, it is crucial to check whether you need this exact diameter for your work and whether it fits your tool's mounting. When choosing, also consider whether the working length is sufficient for the planned holes.

• All 50 drill bits are the same diameter, so the set is mainly suitable for repetitive tasks, not work where you need several different sizes.
• The working length of 100 mm is important when planning the drilling depth; check whether it is sufficient for the specific task.
• The SDS-plus marking means that it makes sense to check whether the hammer has the appropriate chuck before purchasing.
