Overshots

Boart Longyear's overshots are an integral part of the Genuine Q™ Wireline System. Once the inner tube is full of core, the overshot is lowered to the bottom of the hole, and its heavy-duty lifting dogs grab a secure hold at the top of the inner tube assembly.

For maximum productivity in underground or pump-in applications, Boart Longyear offers the new Quick Pump-in™ overshot. The new Quick Pump-in™ overshot provides significantly improved pump-in rates with dual pump-in lip-seals. In addition, it incorporates the proven/reliable, patented Landing Indicator bushing as an optional bypass valve feature. When drilling flat or slightly declined, the landing indicator bushing and valve ball will provide a pressure spike upon landing and allow fluid to bypass the overshot when pulling from the hole, significantly improving retraction rates and eliminating the need to refill the hole with drilling fluid.
