Heule’s BSF tooling is especially useful for counterbores as large as 2.3 x in diameter and ranging in size from 6.5 mm to 20.5 mm (0.256" to 0.807"). This tooling is said to work without an anti-rotation device, change of spindle direction, or any machine adaptations, enabling components to be spot faced in the same direction as the bore is drilled. This saves the time in turning the workpiece while enabling the spot-facing of difficult-to-reach areas like yoke forks, screw-head countersinks and more. The blade expands using centrifugal force when activating the spindle and retracts from coolant pressure, which moves a piston to depress a pin, retracting the closed blade into the housing. The swing mechanism combined with the internal coolant pressure system yields a cutting performance that results in consistent spotfacing and fewer scrapped parts, according to the company. 

The tool works both vertically and horizontally, with replaceable carbide-coated blades for extended tool life. They are especially useful for gear housings, yokes, engine casings and other parts in a range of materials.
