The Toro Drilling Jar is an effective tool for releasing stuck drill pipe. Toro offers four types of performance drilling jars:
- M series: Mechanical
- H series: Hydraulic
- HM series: Hydraulic-Mechanical
- HM2 series: Hydraulic-Mechanical (two unit)
The Toro M series Mechanical Jar utilizes a mechanical lock for activation for both up and down jarring action. The jarring action is instant and without delay.
The Toro H series Hydraulic Jar provides a full hydraulic action with a 1-2 minute delay for both up and down jarring.
Toro offers both single unit and a two unit hydraulic-mechanical jars. The HM series Hydraulic-Mechanical Jar offers a combination mechanical-hydraulic action in a single unit while the Toro HM2 series Hydraulic-Mechanical Jar utilizes a two piece design. Both jars use a mechanical release action for jarring down and a hydraulic delay action for jarring up.
