HEULE SOLO, an easy-to-use front and back spotfacing and formsinking tool, functions reliably without an anti-rotation device, change of spindle rotation, coolant pressure or contact mechanism. The SOLO tool is immediately ready for operation on any machine (CNC, transfer, multi-spindle or conventional machine). The completely closed tool design (tool head) prevents any coolant contamination. In addition, the pin driven cutting blade, which moves in and out radially, prevents chips from jamming the system. Each SOLO Tool is modular and comes with quick change cutting blades that can be changed without removing the tool from the machine. A common tool head can accommodate any configuration of pilot housings and cutting blade configurations. |

There are two different models of the SOLO tool, the SOLO and the SOLO 2. Each tool is capable of reaching counterbore sizes two times the bore diameter minus 1mm. Possible applications up to 30mm through hole. (Max ratio = Ødx2 - 1mm). The SOLO uses two centrifugal weights installed in a sealed tool head. With an activation speed rate of 1900 rpm, the weights start moving outwards and turn the gearwheel. The gearwheel drives the blade out by rotating the blade control. When the spindle is stopped, a pull back spring pushes the centrifugal weights back to the center and retracts the blades. The SOLO 2 uses similar parts, but works in the opposite way. With an activation speed rate of 2000 rpm or higher, the blades retract when the centrifugal weights move. When the spindle rotation is below 1500 RPM, the weights are pushed back to the center and the blade is fixed in the cutting position. Optional: SOLO S2, a larger SOLO head (blue ring) may be used for bores larger than approximately 22mm  Fig. 1: Spindle stopped: SOLO → Blade retracted; SOLO2 → Blade extended Fig. 2: Spindle rotating: SOLO → Blade extended; SOLO2 → Blade retracted |
