Use this tap for reed replacement.
A pilot hole for this tap can be drilled with a 3/64" drill bit - that's a commonly-available drill bit in the US and Canada. In most cases, the rivet hole is already the perfect size and no further drilling is needed.
To use this tap, I recommend you use a tap handle or pin vise. I can provide one if needed.
This pin vise can hold a single M2, M1.6 or M1.4 tap. Use two sets of pliers to tighten the collet so that you firmly hold the tap or drill bit in the pin vise. This will maximize the life of the tool.
