Description
T-Rex Automatic Chain Sharpener
Sharpening shouldn’t slow you down. The Dinasaw T-Rex is a fully automatic chain sharpener that eliminates the time, strain, and inconsistency of manual sharpening. Designed for sawmills, arborists, and forestry operators, it delivers perfectly sharpened chains every time — fast, accurate, and effortless.
Manual filing wastes hours, causes fatigue, and wears out operators. The T-Rex does the hard work for you, sharpening at an incredible 30 teeth per minute. That means chains are ready in minutes, not hours — saving on labour costs and minimising downtime. The result? Sharper chains, longer bar life, and lower overall operating costs.
Trusted worldwide by mill operators — the T-Rex is built tough in Australia to withstand the harshest working environments.
