<p>The HSS Hand Tap is a set of three pieces: Taper, Second, and Bottom tap.</p>
<p>&nbsp;</p>
<ul>
    <li>
        <p>The HSS Hand Taper Tap has a visible and pronounced tapering of the cutting edges. This provides a gradual and less aggressive cutting action. The distinct feature is the 8 to 10 threads that taper from the tip to the full cutting force diameter. A HSS Hand Taper Tap is normally used as the first tap for difficult blind holes. The gentle taper of the cutting edge allows the cutting of a straight hole in especially hard materials. The HSS Hand Taper leaves incomplete threads cut at the bottom of a blind hole and so is never used as the final tap.&nbsp;</p>

        <p>A Plug tap or the HSS Hand Second Tap has a less pronounced taper to the cutting edges giving it a gradual cutting action that is less aggressive than that of the HSS Hand Bottom Tap but more aggressive than a HSS Hand Taper Tap. The plug tap will have 3 to 5 tapered threads before the full cutting diameter is engaged. The HSS Hand Second Tap is great when used with through-holes, as are as easy as the Taper Tap to start with, but also offer a more complete set of threads.&nbsp;</p>
