RUKO annular cutters are made of heavy-duty high speed steel (M2). Suitable for steel (such as T-brackets, large sheets), cast iron, non-ferrous and light metals. Optimized cutting edge geometry for increased cutting performances and reduced cutting forces. The effective cutting angles are designed for universal use in various sorts of steel. Improved removal of chips thanks to U-shaped recesses, it reduces the thermal load on the cutting edges. Reduction of the friction between the annular cutter and the workpiece.
