The ILTS-130 series, light weight electro-mechanical core drills, have been operated in various locations. Some as short as 1.4 m and as light as 20 kg, yet capable of taking a 0.4 m length ice core in one minute, with a power input of 400 W. They are suitable for drilling to 30 m depth.
An extended version, 2.4 m in length and 28 kg in weight, took a 1 m length ice core in 2 minutes, during a laboratory test. This drill will be used in 1983 in Antarctica to replace the JARE-MID-140B drill, which, in 1980, cored a 100 m hole in 44 h and another 143 m hole in 81 h.
The basic design of the ILTS-130 series is described. Suggestions for further improvement and comments on planning a drill system are also included in the paper.
