Gun Drill Tool | Deep Hole Drilling | Gun Drill Manufacturers

Deep-Hole Drill was initially invented for ‘Gun-Driiling’application in Europe during the second world war, and since then it’s popular as Gun-Drill. However, last 75 year, its applications are extended automobile and other engineering metal cutting industries for Deep-Hole Drilling. still, these Deep Hole Drills are yet popularly called ‘Gun-Drills’, even if other used for other applications. It is a thin cutting tool to produce hole in a metal at high depth diameter ratio

What is Gun Drill Tool?

For exceptionally precise deep holes in metal work pieces, Gun drill tool are perishable tooling components that enter coolant through the machine spindle and midsection of the tool, and exhaust chips in a groove along the length of the tool.

A sophisticated grinding equipment, or CNC cutter grinder, can be used to sharpen gun drill tool numerous times to extend their life. For form tool operations, customised forms can also be machined into gun drill tooling tips.

By using high pressure coolant for clean chip exhaust, the gun drilling method can drill deep holes beyond what is achievable with conventional gear and tooling such as twist drills, even at extreme depths.

Gun drilling was first established for the production of gun barrels, when straightness and barrel durability were both required for proper operation. For maximum performance and utilisation on current, specialised gear, the gun drilling technique and tooling have been optimised. Gun drilling is still widely used in the firearms industry. Diesel fuel components, medical tooling, plastic injection moulds, and other industries are among the others.

Accusharp Cutting tools have entered into this new segment of Round tools For Deep Hole Drilling applications. The applications are for deep hole drilling On Crankshaft, Engine-Blocks, turbo-Blades, Paper Rollers, Machine Tools, and Fixturing etc. we are the leading Gun drill tool manufacturers from pune.

The main purpose of a gun drill tool is to drill consistent holes in one pass. The machine work is therefore fairly simple. The entire machine consists of the gun drill itself, the machine, the coolant supply system, the work holding fixture, and the part handling equipment.

Standard geometry for Gun Drill has been shown herewith. However, it may change according to its applications for different work materials and machining parameters. Moreover any change, in cutting edge geometry will have an effect on bore surface finish, geometrical accuracy, drill centring, chip shape, chip removal, process reliability and useful life of the Drills etc.

Deep Hole Drilling

Gun drilling is a deep hole drilling technique that produces holes in metal with large depth-to-diameter ratios by using a long, thin cutting instrument. Gun drilling works on diameters ranging from 3.00mm to 32 mm.

The distinctive head shape of a gun drill tool distinguishes it from a normal twist drill; a standard gun drill has a single effective cutting edge that removes chips as it advances into a metal work piece.

Gun drilling was first established for the production of gun barrels, when straightness and barrel durability were both required for proper operation. For maximum performance and utilisation on current, specialised gear, the gun drilling technique and tooling have been optimised. Deep hole drilling utilized in a variety of industries. Gun drilling is still widely used in the firearms industry. Diesel fuel components, medical tooling, plastic injection moulds, and other industries are among the others.

Gun drilling can be done on standard CNC machines, but only to a limited extent. To achieve the best productivity and process dependability, more often than not, specialized equipment is required.

Accusharp cutting tools provide perfect deep hole drilling solutions for customer problem.

ACCUSHARP Gun drills are straight fluted drills which allow cutting fluid (either compressed air or a suitable liquid) to be injected through the drill’s hollow body to the cutting face. ACCUSHARP drills used for deep drilling—a depth-to-diameter ratio of 300:1 or more is possible. Gun barrels are the obvious example; hence the name.

Other uses include moldmaking, diemaking, and the manufacture of combustion engine parts such as crankcase, cylinder head, and woodwind musical instruments, such as uilleann pipes, as gun drills can drill long straight holes in metal, wood, and some plastics.

The coolant provides lubrication and cooling to the cutting edges and removes the swarf or chips from the hole. Modern gun drills use carbide tips to prolong life and reduce total cost when compared with steel tips. Speed of drilling depends on the material being drilled, rotational speed, and the drill diameter.

Gun drill tool are easily consolidated with CNC machining centres, lathes and milling machines for a reasonably small investment, which makes these tools economical for a small or large business with varying production requirements.

Our standard grinding geometry can take care virtually of all drilling operations successfully. However, for any special working conditions like deep hole drilling long chipping material that is difficult to machine. we design and manufacture Gun-Drills with special geometries accordingly.

Our Present range of Gun drill tool is of Diameters between 4 and 30 mm, having length up to 1000 mm.
