DIAGER Ultimax 168 SDS Max Hammer Drill
Ultimax | Reference 168
SDS Max drill-bit family for hard and reinforced concrete. The principal range uses six cutting edges; DIAGER’s 2026 catalogue marks the 12 mm and 14 mm standard variants as two-cutting-edge versions.
DIAGER Ultimax 168 SDS Max drill-bit family
Ultimax reference 168 is Diager’s long-length SDS Max family for hard concrete and reinforced concrete. The principal six-cutting-edge range combines three self-centring carbide breaker plates with a progressive core and two large clearing channels.

The video shows the Ultimax long-length format and its intended reinforced-concrete drilling context. Final tool choice still depends on the rotary hammer, diameter, total length and working depth.
How the cutting head and flute work
Diager’s 2026 catalogue describes simultaneous action across the six edges to break the concrete.
The head geometry is intended for hard concrete and reinforced-concrete drilling.
The progressive core and clearing channels support debris removal through the hole.
