Undercut Drilling Bit
Daring diamond drill bits are made from diamond material and sintered using nanotechnology. The optimized combination of increased drilling capacity and larger hole expansion with a smaller diameter effectively shortens drilling time and prolongs the lifespan of the tools. They are suitable for Daring-A portable perforators and Daring-C desktop perforators.
