Sim-Cas 33

Available Shanks: Mach 303, IR DHD 3.5

The Sim-Cas 33 Shoedrive system is designed to be used with either threaded or welded casing, with a recommended outside diameter of 4 1/2" and an inside diameter of 4". When in operation the eccentric bit extends to produce a bore size of 5", reducing to 3 1/2" when it is retracted.

The casing drive shoe is available with either a spigot-type connection or a face butting-type connection. The internal diameter of the casing drive shoe is 3.64". This enables a button bit with a diameter of 3.60" (or less) to be used to drill through the casing if required.

An optional stabilizer is available.
