Schmidt Replacement Carbide Inserts for ID20135 Single T&G Lock-Mitre Set

Replacement carbide inserts for the Schmidt ID20135 single tongue-and-groove lock-mitre insert cutter set. Indexing to fresh edges keeps the lock-mitre joint cutting to an accurate fit and consistent diameter — no regrinding the body. Carbide holds its edge through hardwood, plywood, chipboard, and abrasive glue-bonded stock.
