Maxdrill Rock Tools Co., Ltd products

Maxdrill’s concentric casing system can be applied to overburden formations with complex topographic and geological conditions, such as gravel, fissure formations, boulder, landfill of construction refuse, etc.

Drilling through formations with loose, unconsolidated material always comes with problems such as the borehole caving in or collapsing. How to avoid these problems? With years of field practice and research, Maxdrill has developed its concentric casing system with blocks applicable to piling, backfill, hole drilling in pebble formations within 40 meters in depth.
