HMS 3000 stinger bit board. 3 foot
The HMS 3000 stinger board system operates with minimal contact area, allowing for very low downward pressure on the edge. The HMS 3000 board comprises one solid piece with integrated support for maximum stability. The stinger bit holes are drilled with high precision to ensure the stingers can rotate reliably and will wear evenly throughout their lifetime.
The HMS 3000 system protects the grader better and is far stronger than stinger boards with individually welded adapters for each stinger. If some stingers take an impact from a manhole, for instance the wedge bolts break to protect the grader and the solid stinger board remains undamaged.
