Ejector and BTA Drill Bit
We are a Manufacturer of Ejector and BTA Drill Bits in India, where BTA stands for boring and trepanning association which developed this deep hole drilling system. The drill bit contains a single drill tube in which a high-pressure coolant is supplied to the drill through the annular area between the drilled hole and the tube's outer diameter.
Ejector Drills are considered faster than gun drilling, known for cutting straighter holes with excellent tolerances. These are used on conventional and CNC types machines.
