is it possible to easily adapt a coolant fed gun drill to be use in a normal lathe?
For longer lenghts gundrills are supported by several rests which are mounted in a seperate guideway So that is the part you are missing beside the high pressure coolant pump To overcome this problem one can use drills of different lenghts So you first drill with the 30cm long drill Then with a 60cm and then with a 90cm or there about You can ask your supplyer which lenghts are needed The following drills also often are about 0,02mm undersize of the previous one Also you have to predrill with the exact right size I have seen it beeing done with mist coolant and airpressure also Horizontal does function better than vertical then peter from holland
