Tap Flute Grinding

Tap Flute Grinding Benefits

Tap Flute grinding is another  method of resharpening taps.  By grinding the taps flute face for the full length of the lead and threads this removes the worn, dull cutting edges to restore the tap to its original cutting condition.  The benefit to regrinding the flute face is this reconditions the tap with no loss of tool length.

Change in Rake / Hook

Change in Rake / Hook

Flute grinding also effects the rake or hook face.  Rake can be positive, negative or neutral depending on the material being tapped, so It is important that it is maintained during resharpening. At TapSaver we pre-inspect taps for hook / rake to duplicate it when resharpened.  At this time, if a change in rake / hook is desired It can be done.
