PCD and CBN tips for notching
Milling of rebar notches on cemented carbide rolls.
Most common is PCD (Polycrystalline Diamond) with full face PCD layer
Stepped execution is less frequently required – small PCD tips are brazed on a cemented carbide shaft.
All tips are executed in special micrograinsized grades with polished surface and precision ground cutting edge, providing best performance on all carbide grades for rebar rolling (30% binder down to 15% binder) due to:
• exceptionally high wear resistance
• outstanding impact strength
• very good surface finish
• record tool life
