GRAPHITE DESIGN INT'L TRIMMING INSTRUCTIONS

Special Head Preparation For Installing Any
Graphite Wood or Iron Shaft

  • Chamfer exit point of hosel with 20 degree coning tool. If hosel is not chamfered, stress will cause graphite shaft fibers to break, rendering the shaft unsafe and unusable. The use of a chamfered (countersunk) ferrule is a MUST on all graphite shaft installations.
  • Ream hosel to smooth rough spots on inner surface and deburr chamfered edge. If sharp edges remain in hosel they will cut into the graphite fibers during normal use and, eventually, cause shaft failure. Clean hosel and shaft thoroughly before assembly.

    1.  Tip trimming amounts above are the "maximum" recommended for each head type and number.  Lesser amounts will, generally, result in better feel and performance.  If a stiffer flex is required to match a specific swing profile, go to the next stiffer shaft instead of performing excessive tip trimming.  If this isn't done, the result will be a club that has a "boardy" feeling and performance will be reduced.

    2.    Graphite Design warrants their products against poor workmanship and material defects in manufacturing for a period of 1 year.  Poor installation practice voids this warranty.
