Dormer expands Hydra hole-making lengths for more drilling options

Dormer has expanded its Hydra replaceable head drill body options. Designed for large diameter drilling, the Hydra program supports structural and general engineering applications.

The range of solid carbide heads, for steel, stainless steel and cast iron, are married together with a high-speed steel body. Existing body options, which includes 3xD, 5xD and 8xD, have been expanded with a 12xD for deep hole applications and a 1.5xD for improved rigidity in shallow hole and plate drilling.

The range of bodies incorporates coolant holes to improve cutting efficiency and chip evacuation. The exact fit between head and body maximizes tool rigidity for superior hole accuracy and precise tolerances. Also, one body can fit multiple solid carbide head sizes, reducing inventory requirements. In addition, heads can be easily changed without removing the body from the spindle, minimizing machine downtime.
