Dormer Pramet R950 Hydra Drill Heads - Steel Grade

Dormer Hydra a high performance replaceable head drill system – provides a cost-effective large diameter drilling alternative to solid carbide drills.


The R950 are available in diameters up to 42.0mm and has been developed specifically for drilling operations in carbon and alloy steels and has a self-centering 140-degree four-facet split point. This feature ensures low thrust forces throughout the drilling cycle, promoting consistent performance.

Benefits of Hydra are the heads can be quickly and easily changed without removing the body from the spindle, thus reducing machine downtime. The high speed steel construction of the bodies ensures an extremely cost-effective solution. Coolant holes in the drill bodies are aligned perfectly with the replacable heads for efficient delivery of coolant directly to the cutting edge. This not only disperses the heat generated during the hole making process when using high speeds and feeds, but also ensures smooth chip evacuation and long tool life.

Each head is available with a range of drill bodies to support drilling depths to 3xDiameter (H853), 5xDiameter (H855) and 8xDiameter (H858). One body can accommodate multiple head sizes with no compromise on structural integrity.

Availiable in 12.0 to 42.0mm.
