1. A boring tool resistant to vibration comprising:
- a boring bar having a central bore at one end;
a boring bar head with means for attachment to said boring bar at said one end; and
a tuned absorber package inserted in said bore for eliminating vibrations in said boring tool, said tuned absorber package having means for being self-contained and transferable between boring bars, said tuned absorber package comprising;
an absorber mass;
an elastomer support on either end of said absorber mass;
a cylindrical canister for receiving said absorber mass and said elastomer supports;
an end cap for said cylindrical canister;
tuning means interacting with one of said elastomer supports so as to tune the desired vibration frequency of said absorber package; and
dampening fluid within the cylindrical canister.
