Detailed introduction

The wide range overshot is the strongest fishing tool available and can engage, seal and lift heavily worn fish, providing seal for very large extrusion gaps at high or standard pressures, and ensuring that drilling fluid flows completely through the fish. The new coarse thread on the top sub and bowl ensures greater tensile and torsional strength, increasing the assembly speed, allowing the inner diameter of the top sub and the extension expand, allowing max. size fish pass through.
