SDS-MAX Rotary Hammer Drill Ultimax 166D DIAGER

Drilling Technology

This diamond-tipped crown incorporates a self-centering triple concrete-breaking segment system for immediate starting and optimal stability from the very first rotations. The progressive-core helical architecture ensures efficient debris evacuation and constant penetration into hard materials. Each carbide segment features 6 sharpened cutting edges that retain their sharpness over long intensive drilling sequences.

Compatibility & Mounting

The mounting fits the SDS-max standard, ensuring optimal transmission of impact energy and a secure connection on compatible corded and cordless rotary hammers. This locking system allows quick tool changes without additional tooling.

Performance & Durability

The drilling delivers perfectly cylindrical holes with precise nominal dimensions, eliminating geometric defects and post-drilling reworking. The exceptional abrasion resistance of the carbide segments multiplies the useful service life, while the optimized geometry of the evacuation channels minimizes jamming risks in reinforced concrete or natural stone.
