Provided is a system and method for a hand tool with a plurality of quick release work heads. The hand tool includes a handle having a socket having a first longitudinal axis and an inner cavity extending rearward from an open distal end, the inner cavity having a first non-circular cross section transverse to the first longitudinal axis, the socket further having a quick release transverse to the first longitudinal axis, the quick release releasably disposing a locker transversely across a portion of the inner cavity. The hand tool also includes at least one work head having a second longitudinal axis and a shaft having a second non-circular cross section concentrically conforming to the first non-circular cross section of the inner cavity, the shaft further having a locking groove transverse to the second longitudinal axis and disposed to engage with the quick release locker when the shaft is disposed within the socket of the handle. An associated method of use is also provided.

In one aspect, cam bolts are described herein employing a dual cam surface architecture. In some embodiments, a cam bolt described herein defines a longitudinal axis and comprises a first end, a second end, at least one engagement member disposed on at least one of the first end and the second end, at least two first cam surfaces, and at least one second cam surface. The engagement member is configured to engage a torque implement to rotate the cam bolt about the longitudinal axis when torque is applied by the torque implement. The first cam surfaces are disposed about the longitudinal axis and have a first cam profile. The second cam surface is disposed about the longitudinal axis between the first cam surfaces and has a second cam profile differing from the first cam profile. At least one of the first and second cam profiles can be non-circular.

A reamer includes a shank, a washer, a ring and a blade. The shank is a polygonal rod and includes an annular groove made in a periphery and a bore made in an end. The washer includes a slot. The ring includes a circular opening. The blade includes an insert inserted in the bore through the slot and the circular opening. The circular opening is made of a diameter larger than a width of the blade to allow the blade to rotate relative to the ring.
