Heule’s BSF tool is engineered for automated, high-volume back-spotfacing applications to save time and cost. Developed for counterbores ranging to 2.3×D, the tool ranges in size from 6.5 to 20.5 mm (0.256" to 0.807") in diameter. It is said to function without an anti-rotation device, change of spindle direction or any machine adaptations. Parts can be spotfaced in the same direction as the bore is drilled, accommodating applications with difficult areas like yoke forks, screw-head countersinks and more.

The tool blade expands using centrifugal force when activating the spindle. The blade reacts to coolant pressure, which moves a piston to depress a pin, retracting the closed blade into the housing. When combined with the internal coolant pressure system, the swing mechanism is said to yield optimal cutting performance, resulting in consistent spotfacing and fewer scrapped parts.

The tool works both vertically and horizontally, with replaceable carbide-coated blades for extended tool life.
