The LiMAR Collapsible Broach functions similarly to the LiMAR Fixed Broach options with the added safety feature of reducing in diameter when jarring upwards.
During broaching, the Collapsible Broach expands to the full running OD and is strengthened by incorporating a series of support profiles to prevent undue stress on a specific point and ensure the running OD is maintained. Material hardness is of critical importance. Too hard externally or through-hardened can result in embrittlement, breaking and leaving potential fish in the well. LiMAR Collapsible Broaches are supplied with full material hardness checks which document external and internal hardness measurements.
