FIELD: bore-hole drilling equipment. SUBSTANCE: this relates to drilling tools intended for drilling bore-holes with testing of perspective formations. Bore-hole drilling setup has drilling bit, tester which is made up of packer unit connected with drilling bit, body with its inner space creating sample-taking chamber, hollow rod which is located inside body and rigidly connected to drilling string with possibility of displacement inside body. Hollow rod is made with external groove which takes position against radial holes in packer unit when drilling setup is in working position. EFFECT: higher efficiency. 1 cl, 5 dwg
