Claims: What is claimed is:

1. In a machine tool utilizing interchangeable tool heads, the boring tool head comprising:

a. a housing, having an input face adapted to be received on a machine tool, and further having an output face disposed away from said input face on said housing;

b. an input shaft passing through said input face, rotatably mounted and centrally located within said housing;

c. an output shaft, passing through said output face, rotatably carried in said housing and displaced from said output shaft and drivingly connected thereto;

d. a boring arm, having one end connected to said output shaft and having the other end supporting a boring tool such that rotation of said output shaft causes said boring tool to swing in an arcuate path, wherein said arcuate path extends beyond the perimeter of said housing when viewed along the axis of said arcuate path; and

e. a latching mechanism affixed to said housing and operable to maintain said boring arm in a predetermined angular position while transporting said tool head to and from a tool head storage matrix, and further operable to automatically release said boring arm for free rotation when said tool head is employed for use at a machining site.

2. The tool head of claim 1, wherein the length of said boring arm measured from the center of said output shaft is less than the furthermost radial dimension from the center of said output shaft to the edge of said output face.

3. The tool head of claim 1, further comprising registering means affixed to said housing input face, to locate said housing on a cooperating machine tool registering means.

4. The tool head of claim 1, further comprising a suitable coupling affixed to said input shaft to connect said input shaft to a prime mover shaft on said machine tool.

5. The tool head of claim 1, wherein said latching mechanism comprises a detent means having a detent pin operable to engage and disengage a pin socket in said boring arm.
