Designed to deliver durable performance in demanding environments, this tap helps you achieve precise M3 x 0.5 threads in through-hole components across a range of metals. The TiCN coating lowers friction for faster cutting and smoother feeds, while the powder-metal construction resists wear and heat buildup for long tool life. The spiral-point geometry aids chip removal, reducing the risk of chip clogging and ensuring consistent thread quality across materials. This makes it ideal for electronics enclosures, small mechanical housings, and other precision through-hole assemblies where reliable internal threads are essential.
