Welded gun dril bit partis carbide, the rod is made of steel pipe through the press groove, heat treatment and other processesdrill pipe requirements are extremely hiah, need to have hardness at the same time also need to have high toughnessreguirements, dril, drill pipe and drill shank through welding to form a whole.

Welded single-edge gun dril is the most widely usedtool in the field of deep hole processing.

The gun drilwil dril, boring and reaming at one time, and the hole can be machined withhigh precision (lT6-8), fine straightness (0.16-0.33mm/1000mm) and low roughness (Ra3.2-Ra0.1). lts driling speed reaches 30-100 m/min or more. 

Gun drillis suitable for driling cast iron, carbon steel, copper, aluminum alloy, alloy steel and othermaterials,
welding type gun drill can be the minimum F2mm, the maximum can be F50mm, the longest can be 6000mm.

Coated gun drill is mainly used in some difficult to process materials, such as: stainless steeltitanium alloy, superalloy and other materials, Dehan tools has been committed to coating toolsin a variety of materials on the application and research and development, all our coatings areprocessed by the world famous coating company, the company has a long-term conventionalspecifications coating tool head, so that customers need to use.
