For deep hole drilling, several kind of drills appeared in the history, flat drills, half-round drills, twist drills, gun drills etc. Only gun drills are popular for special features of single cutting edge with self-guiding, automatic chips-removal and cooling lubrication.



Gun Drilling For Deep Holes

Gun drilling is a precision deep hole drilling process that uses a long, straight tool to produce extremely deep holes in a variety of materials. This tool has a unique head geometry, and a groove along the length of the tool, differentiating it from a conventional twist drill.



What Is Deep Hole Drilling

Deep hole drilling is beneficial across several applications. Oil and gas exploration equipment, armaments, aerospace equipment, and engines are common applications for deep hole drilling and machining processes. In each of these industries, hole qualities are necessary for high-performance end products, such as landing gear that easily retracts. Production requires deep hole drilling that is reliable, accurate, and time-efficient.



Designed Tools To Polish Blanks Of Outer Diameter

Outer-diameter polishing of blanks is always a complicated step for manufacturing blanks for gun drills. Our experienced engineer designed two kind of tools to polish profiled blanks or short blanks with single coolant hole or twin coolant holes.
