Proliferation in the use of high pressure coolant systems as a machining aid fostered the development of Titespot® Coolant Driven Right Angle Drill Heads, Spindle Speeders, and Keycutters by Eltool Corporation. Compared to spindle driven heads, Titespot® angle drill heads have two important cost-savings advantages: they are indexable, allowing multi-position machining with one angle head and set-up, and their compact profile allows machining in bores and cavities not accessible to mechanical heads. Eltool Angle Heads can machine in bores down to 5/8″ in diameter and develop up to 4 Horsepower.
