Overview
A metric M3 x 0.5mm machine tap made from HSS (high speed steel) for cutting right hand threads, weighing about 0.317 ounces.
The category label Threadings is unusual, but title and specs agree this is a thread cutting tap sized for M3 x 0.5mm fasteners, a common size in electronics, small machinery, and hobby metalwork. HSS construction is a standard choice for taps because it holds an edge through repeated thread cutting in metal.

Who it's for
Suited to machinists, model makers, and hobbyists who need to cut or repair M3 threads in metal parts. Not useful for anyone working with larger fastener sizes, since this tap is sized specifically for M3 x 0.5mm.
Strengths and trade-offs
Drawn from this product's published specifications.
- HSS material holds an edge for repeated thread cutting
- Precise M3 x 0.5mm sizing for small fastener work
- Single size tap, not a set
- Very light weight tool with a narrow use case
Performance notes
HSS tools stay sharp longer than lower grade carbon steel when cutting threads in metal, which matters for a tap since a dull cutting edge can strip or distort small threads. Because M3 is a fine, small thread size, precision matters more than raw force when using this tool.
