El Tool’s coolant-driven angle heads develop as much as 100 inch-pounds of torque. The heads incorporate a planetary gear with a 5:1 ratio, said to be ideal for applications where high torque at lower speeds is required. The angle heads are powered by an integral positive displacement ball piston motor driven by the machining center’s high-pressure coolant system. Because spindle rotation is not required for power, the spindle can be indexed for multi-position machining with one angle head and one setup. The compact, elliptical head design allows radial machining in bores as small as 1" in diameter. Offered in milling and drilling versions, the heads are available in all popular shank styles and load easily from the ATC, the company says.

This system allows shops to quickly transform the standard external-coolant live tooling heads on their turning machine turrets into those with through-tool-coolant capability.
