Herdim Calibrated Stop Ring for Peg Reamers, 7.8 mm

Offer the highest advantage when used with Herdim System Pegs. Vastly used diameters of pegs 7.8 and 8.2 mm fit any either new or re-reamed holes, and the use of matching reamer and shaper makes the job easy even for non-professional and avoids mistakes and misperfections. The appropriate reamer ring adjusts the exact reaming depth, leaving the peg collar overlap 13 mm outside of the pegbox.
