Accusharp Gun-Drills Make Deep-Hole drilling more efficient and easy for you. Deep-Hole Drill, as initially invented for ‘Gun-Drilling’ application in Europe during the Second World War; and since then is popular as ‘Gun-Drill. However, over last 75 year, its applications are extended in Auto and other engineering metal cutting industries for Deep Hole Drilling. Still these Deep-Hole Drills are yet popular and called as ‘Gun-Drills’, even if used for other applications. Accusharp Cutting Tools have entered into this new segment of Round Tools for Deep-Hole Drilling applications; and call them as ‘Gun-Drills’. The applications are like deep holes drilling on Crankshaft, Engine blocks, Machine Tools, etc. Standard geometry for single lip Gun-Drill drill has been shown herewith. However, it may change according to its applications for different work materials, and machining parameters. Moreover, any change in the cutting edge geometry will have effect on bore surface finish, geometrical accuracy, drill centring, chip shape, chip removal, process reliability, and useful life of the drill, etc. Our standard grinding geometry can take care of virtually all drilling operations successfully. However, we design and manufacture Gun-Drills with special geometry for deep drilling long chipping material or material that is difficult to machine We manufacture and supply Gun-Drills in the range of Dia. 4 to 30 mm., having length up to 1000 mm.
