Blade Body:
Chrome-Vanadium Steel bodies are flat ground and finished to a fine finish. Blades are levelled and tensioned to ensure vibration free, accurate cutting at operating speeds.

Segments:
Manufactured from HSS with three hardness zones to provide a tough joint zone and a hard working zone with a tempered transition zone between the two.

Our standard segment is now the European standard 4 rivet hole pattern. There are also a limited range of 3 hole rivet segments available. Segments are grooved to fit onto the tongue of the blade body.

All segments are taper ground to provide adequate clearance throughout the working life of the segment. Accurately ground cooling channels allow cutting fluid to penetrate to the cutting edge.

Tooth Profiles:
Heller triple chip tooth form is standard, the high roughing tooth is chamfered on both sides and so only cuts in the centre and is alternated with the 0.38mm (0.0015") lower finishing tooth which completes the cut.
