By dealing with us, you venture into a partnership with a one-stop shop for each and every deep hole-drilling requirements.

Technology of Micro Gun Driller Machines:

The working process followed in micro gun drilling machines was developed only to drill into Gun Barrels and was exclusive to the Defence Industry. With the passage of time, this technology expanded and found use in industries such as medical implants, die & mold, automotive, oil & gas, aerospace and others. This technology and machine is ideal for increasing the process productivity and reliability.


Conventional drilling standards are not enough if it is desired to achieve increased tool life and surface finish along with precise hole straightness. The gun drilling technology or process is used for making deep and straight holes. When compared with the conventional twist drilling technology, our machine can eccentrically cut through the metal. Furthermore, once the bit is inside the component, then the tool self-pilots itself. Further, burnishing of the hole is done with help of guide pads. This makes the hole precise in terms of round shape and straightness. After wards,

  • Coolant is inserted via the hole into the tool
  •  Chips are gushed out via V shaped profile
  • The effectiveness of Gun Drilling is from 1 to 30
