a generally cylindrical body suited for grasping;

an attachment device, disposed generally on an end of the generally cylindrical body, said attachment device being configured to attach the handle to a hand-held power tool;

a hand guard disposed adjacent the attachment device on the generally cylindrical body; and

a mechanical device connected to the hand guard and spaced from the generally cylindrical body portion, said mechanical device comprising a truncated portion of the hand guard and two projections;

wherein the generally cylindrical body is configured to be held by a user's hand to manipulate the mechanical device which is configured for at least one of securing and un-securing a work attachment to the hand-held power tool.

2. The handle assembly of claim 1 , wherein the assembly is a removable auxiliary handle.

3. The handle assembly of claim 1 , wherein the attachment device is a threaded shaft which extends coaxially with an axis of said generally cylindrical body portion.

4. The handle assembly of claim 1 , wherein the handle assembly is configured for attachment to at least one of a drill, a grinder, and a reciprocating saw.

5. The handle assembly of claim 1 , wherein the handle assembly is configured to attach to at least one of a pneumatic angle grinder and an electric angle grinder.

7. The detachable auxiliary handle of claim 1 , wherein the mechanical device is configured to secure/unsecure at least one of a blade, a brush and a grinding stone.

8. A detachable auxiliary handle, comprising:

a generally cylindrical body configured for being grasped;

a threaded shaft, disposed generally on a first end of the body, said threaded shaft being configured to attach the detachable auxiliary handle into a threaded recess included in an angle grinder;

a hand guard disposed adjacent the threaded shaft on the generally cylindrical body; and

a mechanical device connected to the hand guard and spaced from the generally cylindrical body. said mechanical device comprising a truncated portion of the hand quard and two projections; and

a spanner wrench connected to a second end of the generally cylindrical body portion,

wherein the generally cylindrical body is configured to be held by a user's hand to manipulate the spanner wrench or the mechanical device which are configured for at least one of securing and un-securing a work attachment, and

wherein the first end of the body is on a substantially opposite end of the body from the second end of the body.
