What is BTA Drilling?
BTA deep hole drilling is used for larger hole drilling, typically 20 – 200 mm [0.80 – 8.00 in] in diameter High-pressure coolant is introduced around the outside of the tool through the pressure head assembly Chips are discharged through the tool center, through the drill tube and machine spindle
BTA drilling typically performs 5-7 times faster than gundrilling, and requires higher power
Additional extended diameters can be drilled on BTA machines with secondary deep hole operations, such as counter-boring.
