Ultimax SDS Max Hammer Drill Bit DIAGER 168, Ø12–25mm, 6 Cutting Edges, for Reinforced Concrete

Ultimax SDS Max Hammer Drill Bit DIAGER 168, Ø12–25mm, is designed for users seeking reliable performance in drilling reinforced concrete and other tough materials. The bit incorporates advanced 6-cutters technology, starting with four peripheral and two central cutters working together for efficient concrete splitting.

This construction ensures precise, stable drilling and reduces vibration, which is essential for demanding site work. The self-centering carbide tip extends the tool's lifespan and maintains accuracy throughout repeated use. Large clearance gouges are integrated into the design to promote rapid dust removal, supporting high drilling speeds and minimizing clogging during deep or continuous drilling sessions.

The SDS-max shank is compatible with rotary hammers over 5kg, providing secure attachment and optimal power transfer. The bit is available in a range of diameters from 12mm to 25mm, with working lengths of 200mm and total lengths of 340mm, ensuring flexibility for various construction and installation needs. This makes the Ultimax DIAGER 168 suitable for both standard and technical drilling applications where reinforced concrete, stone, or solid brick must be penetrated efficiently and with minimal tool wear.
