Dormer E500 HSS Coarse Tap, Straight Flute, 3.5mm, Second

The Dormer E500 HSS Coarse Tap features straight flutes, making it the only type of tap suitable for hand use, though it can also be utilised in a machine when required. This versatility allows it to handle both through holes and blind holes in most materials, making it an essential tool for precise threading operations.

For blind holes, it is recommended to use straight flute taps in sets. A standard set includes three taps, each serving a specific purpose: the taper (first) tap, the second (intermediate) tap, and the bottoming (third or plug) tap. The E500 is specifically a second (intermediate) tap, designed for refining the thread after the initial taper tap and before the finishing plug tap.
