"Общая глубина бурения составила 225 сантиметров."
Translation: "Overall depth of drilling was 225 centimeters." That was Luna-24 in 1976, bringing back some Moon rocks.
From Gunter's Space Page Luna Ye-8-5M (Luna 23, 24):
Luna 24 was launched on 9 August 1976, entered lunar orbit on 14 August 1976 and successfully landed on 18 August 1976. The lander deployed its sample drill and pushed its drilling head about 2 meters into the lunar soil. The sample was transferred to the small return capsule, and after nearly a day on the Moon, Luna 24 lifted off successfully on 19 August 1976. The return capsule entered Earth's atmosphere and parachuted safely to the ground on 22 August 1976. The probe returned 170.1 grams of lunar soil.
From Russia Space Web's Luna-24: Last Moon digger:
As in previous soil-return missions, telemetry relayed information to ground control on the performance of the drilling mechanism and the process of loading of the samples into the return vehicle. (393) Data showed that Luna-24's drill reached a depth of two meters under a 30-degree angle toward the local vertical, penetrating 225 centimeters deep into the soil. (398) As a result, a 260-centimeter flexible tube with a diameter of 12 millimeters was partially filled with lunar regolith. The tube was then coiled in a spiral-like fashion on a special drum with a diameter of 80 millimeters, which in turn, was sealed inside the metal storage container of the reentry capsule.
