Evaluation of key product features

⚖️ Compare features with other products of your choice

KWB SDS-plus hammer drills work with a special clamping system that allows for quick and safe bit changes on impact drills and combination hammers. This solution saves users time while working and reduces the possibility of the drill bit slipping in the chuck and resulting damage to the material or tool.

The combination of several different diameters in one set allows you to precisely select the appropriate dimension depending on the project requirements, for example when assembling furniture, installing electrical installations or installing wall elements. The 160 mm length offers a good compromise between accessibility to hard-to-reach places and drilling stability.

The impact drill bits in this set are designed to efficiently transfer the tool's impact directly into the material, helping to drill holes faster and cleaner, even in harder materials. This feature is especially useful in everyday use on construction sites, renovations or home improvement projects where reliability and consistent quality results are required.

Since the drill bits in the set are specifically designed for use with power tools with an SDS-plus chuck, they eliminate the need to find individual dimensions and ensure compatibility with many popular models of impact drills and hammers on the market. This makes it easier for anyone looking for a complete and practical set for a variety of masonry drilling tasks.

It is important to know

This SDS-plus hammer drill bit set is especially useful for users looking for more dimensions for drilling into concrete or masonry with impact drills. It will be most appreciated by DIYers and those who want a practical set for occasional or basic use. Before purchasing, it is worth checking whether all the included dimensions are suitable for the planned tasks and whether your drill is compatible with the SDS-plus chuck.

• The set covers basic diameters, which is useful for universal home use, but before specific tasks, check that the right sizes for your needs are included.
• The SDS-plus chuck means that the drill bits are not suitable for every tool, but only for drills and hammers with the appropriate chuck.
• Drill bits are designed for impact drilling in harder materials; use in other materials (e.g. wood, metal) may impair the result or damage the drill bit.
• The 160 mm length allows for standard drilling depth; if you need a greater reach, check the appropriate length.
