The Noga Deburring System is the ideal tool for sharpening notes on the pipe chanter. Altering the pipe chanter is a highly delicate, irreversible process that should only be undertaken by those experienced in the process. Undercutting the top of the holes with the Deburring System only is recommended rather than changing the shape of the hole. A fine tip suitable for altering the top hand notes is also included. Modifications made using the Deburring System are permanent and done so at the owner’s risk.
