Introduction:
A carbide internal ID micro custom grooving tool for small hole boring is a precision-engineered cutting tool designed for creating intricate grooves, undercuts, or channels inside tiny bores (typically Ø0.5–5mm) with extreme accuracy. These tools combine grooving and boring capabilities in one rigid carbide body for complex internal machining.
