Version:
All blades are hollow ground to give side clearance. All sizes with 200 mm ⌀ and very thin blades have a bore collar for stabilisation. Accuracy, tooth form, and side clearance grinding according to DIN 1840.
DIN 1838 C coarse-toothed with curved form C. High performance tooth pitch (HZ) with high teeth and lower finishing teeth. The roughing tooth is 0.15 – 0.30 mm higher than the finishing tooth and is chamfered at both tooth corners. In this way both types of teeth share the cutting work.
Application:
Particularly suitable for cutting workpieces with low to medium tensile strength. High cutting performance due to the chip breaking tooth form.
Please note: If the component is not cut through, but only cut into, the bottom of the cut will have an additional slot due to the projecting high tooth.
Note:
The concentricity and axial run-out values are considerably better than the figures according to DIN 1840, in some cases by up to 50 %.
