Practical application: Fast, clean and efficient drilling
Whether you are installing an air conditioner, laying electrical and telecommunications cables through thick load-bearing walls or simply installing heavy shelves and elements in a basement with concrete walls - this drill set will never let you down. The innovative S4 square helix ensures that dust and debris are continuously and extremely quickly removed from the hole. This not only prevents the drill bit from getting stuck in the material, but also drastically extends the life of your rotary hammer by reducing the strain on the motor and impact mechanism.
Thanks to the wide range of sizes, you will always have the right drill bit at hand – from short drill bits for quickly fixing cable ducts to massive 45-centimeter drill bits that will easily pierce the exterior walls of buildings.

Frequently Asked Questions (FAQ) about the product
Are these drill bits suitable for drilling into reinforced concrete?
Yes, the drill bits in this set are equipped with an advanced and improved carbide head geometry, which is specially designed to enable drilling even in reinforced concrete. Despite the superior quality and durability of the materials, we recommend caution, even pressure and moderate drilling speed when the drill bit encounters steel reinforcement, as this will extend the life of the tool.
Which rotary hammers are the drill bits from this set suitable for?
The drill bits are equipped with a standardized SDS-Plus (SDS+) chuck. This means that they are fully compatible with all electric and cordless rotary hammers from all established brands on the market that support the SDS+ chuck system. Changing is quick, safe and does not require additional tools.
How does the S4 square helix improve the drilling process?
The S4 square helix is a key technological advantage of these drills. It enables significantly faster and more efficient removal of dust and larger particles from the drill hole. This drastically reduces friction between the drill bit and the borehole wall, preventing the drill bit from overheating. The result is faster work, less effort for the user and drill bits that stay sharp for significantly longer than conventional drill bits with a double-outlet helix.

Same summary

The set of long SDS+ concrete drill bits 5-20 mm is especially useful where you often drill into concrete or other harder materials and need several different diameters in one set. The combination of a wider range of dimensions allows for flexibility in various tasks at home or during renovations, especially when dealing with thicker walls or more complex layouts. Such a set makes sense for users who occasionally carry out DIY projects or household repairs and want to be prepared for different situations. For very specific or professional work, where one type of task prevails, a dedicated drill bit can offer greater efficiency, but a set is a more practical choice for wider everyday use.
