Ultimax SDS Max Hammer Drill Bit DIAGER 168, Ø25–52mm, 6 Cutting Edges

Ultimax SDS Max Hammer Drill Bit DIAGER 168, Ø25–52mm is engineered for demanding drilling applications in reinforced concrete, stone, and solid brick. The bit incorporates advanced 6-edge cutting technology, beginning with a self-centering carbide tip and large flutes to optimize chip removal. This combination enhances drilling speed, reduces vibration, and extends tool life. The SDS-max shank is compatible with rotary hammers above 5kg, making it suitable for heavy-duty operations such as through-hole drilling, slab penetration, and technical installations in construction and industrial environments.

The range covers diameters from 25mm to 52mm, with working lengths from 200mm up to 1360mm and total lengths from 340mm to 1500mm. This variety enables selection for different hole sizes and depths, supporting a wide scope of technical and installation requirements. The robust construction and innovative geometry of the DIAGER 168 series address the challenges of drilling into hard and reinforced materials, providing consistent performance across multiple site conditions.

Each bit in the series is designed for efficient debris evacuation, minimizing heat buildup and wear. The combination of four peripheral and two central cutting edges ensures effective concrete fracturing, while the self-centering tip improves accuracy and stability during operation. The large flute design further aids in rapid chip removal, supporting continuous drilling and reducing downtime for cleaning or bit replacement.
