A standard milling drum shouldn’t be done at 4,000–5,000 hours just because the holder bolts and bolt holes wear out first.
With TH12, we’ve helped push that working life closer to 6,500–7,000 hours. 🔧
The problem with many traditional drums is that too much impact stays on the bolt connection.
That leads to:
⚠️ Loose holders
⚠️ Repeated retightening
⚠️ Ongoing bolt-hole wear
TH12 changes how the holder base carries the load.
Its patented self-locking design moves more force into the drum body and reduces bolt reliance by around 80%.
That also removes the traditional full retightening every 500 hours under normal conditions.
The result is around 1.3× the service life of the original drum.
The old wear cycle comes from the holder design — not because the drum body can’t last longer.
