The type of cemented carbide used for core drilling should meet the following conditions:
①The cutting edge is sharp and the contact surface is small, making it easy to cut into rocks;
② It has greater strength and wear resistance, and is anti-collapse and anti-wear;
③Have appropriate size and shape, and can be firmly welded to the drill bit body;
④The alloy still has a certain cutting ability after wear (that is, it has a certain self-sharpening effect).
There are already shaped products of cemented carbide for core drilling. The shaped products of cemented carbide can be divided into two categories: sharpened alloys and self-grinding alloys.
