Standard Taper Long I.D. Wheel Extensions.*
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.
FOR A SMALL RADIUS OR THAT ONE SMALL SLOT.
SAVE BOTH THE EXPENSE AND SET-UP TIME OF A HIGH SPEED ATTACHMENT.
All LONG IDWEs come with a floating nut spacer 00662 (FN-1), two flanges, and a wheel end-nut. The hex spindle nut must be selected separately to suit your machine. Most grinders use
1/2-13LH or 1/2-13RH threads. A 13/16” wrench flat on the step makes installation and removal easy. See page 76 for available hex spindle nut sizes. Extends grinding wheels 13/16" further from spindle nose than the short series ID wheel extensions shown on page 16.
