Twist lock tool system

A coupling system comprising:

• a liner configured for coupling to a boring fixture and including a first tool passage aperture;
• a housing having a first end configured to couple to a boring tool, a second end configured to couple to the liner, and a second tool passage aperture;
• and
• twist lock elements disposed on the liner and the second end of the housing, the twist lock elements each having mating compound engagement surfaces effecting a coupling between the liner and the housing for coupling the boring tool to the boring fixture;
• wherein the twist lock elements disposed on the liner are configured to allow axial insertion of the twist lock elements disposed on the second end of the housing into a respective twist lock element disposed on the liner and configured to couple the housing to the liner with a relative rotation between the housing and the liner so that engagement between the mating compound engagement surfaces of the twist lock elements disposed on the liner and the mating compound engagement surfaces of the twist lock elements disposed on the second end of the housing aligns the first tool passage aperture with the second tool passage aperture along a common longitudinal axis, where the compound engagement surfaces and the mating compound engagement surfaces are angled in both a circumferential direction and a radial direction relative to the common longitudinal axis.

A method for coupling a boring tool to a boring fixture, the method comprising:

• coupling the boring tool to a second end of a housing;
• coupling a liner to the boring fixture, where the liner has a body and a plurality of coupling members extending from the body;
• and
• coupling the boring tool to the boring fixture through an engagement of mating twist lock elements of the liner and housing, where the housing has a first end with unthreaded ramped grooves that mate with the plurality of coupling members to couple the tool within the unthreaded ramped grooves and to the boring fixture where, the plurality of coupling members have an arcuate shape with compound engagement surfaces that corresponds to a mating arcuate shape, having mating compound engagement surfaces, of the unthreaded ramped grooves so that engagement between the compound engagement surfaces of the plurality of coupling members and the mating compound engagement surfaces of the unthreaded ramped grooves aligns a first tool passage aperture of the housing with a second tool passage aperture of the liner along a common longitudinal axis, where the compound engagement surfaces and the mating compound engagement surfaces are angled in both a circumferential direction and a radial direction relative to the common longitudinal axis.
