The drill tip and drill tube of the solid carbide gun drill are made of cemented carbide, and the driver is made of 45 steel. There are also solid carbide gun drills whose shanks are cemented carbide. The solid carbide gun drill has high concentricity and small radial runout, which reduces the possibility of tool breakage, so the service life is longer than brazed gun drills.

carbide gundrills are widely used in medical equipment, valves, ring moulds, oil nozzles and pumps, automobiles, aerospace and other fields due to their excellent performance in deep hole machining.

Diameter range: 0.9-12mm Length up to: 350mm (without shank)  Effective length: Under 340mm  Filtration accuracy：5-10μm (It is recommended to use special cutting oil for deep hole drilling)
