Undercut Drilling Bit
Welding-type drill bits can be used for drilling anchor holes in dry-hanging panels, mostly made of stone. There are two types of welding-type drill bits: rotary-type anchor drill bits and impact-type anchor drill bits. Each type of drill bit is available in multiple specifications, corresponding to the anchor models. Additionally, welding-type drill bits need to be used with the corresponding drilling machines and are not compatible with electroplated drill bit machines.

Product Description
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.
