Sim-Cas 88

Available Shanks: Mach 80, A63-15 (SD8), DHD 380

The Sim-Cas 88 Shoedrive system is designed to be used with either threaded or welded casing, with a recommended outside diameter of 10 3/4" and an inside diameter of 10". When in operation the eccentric bit extends to produce a bore size of 12 1/8", reducing to 9 1/4" 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 9.33". This enables a button bit with a diameter of 9.29" (or less) to be used to drill through the casing if required.

An optional stabilizer is available.
