Measuring 0.20" in diameter, with three cuts through its center, provides the user with a fairly aggressive pattern. This tip also works great on denser materials such as MagPul P-mags. If one sands and polishes the stippling, it can be a suitable concealed carry texture (see last pic).
One may use the tip in an overlapping pattern for a random texture, or stipple over a lighter texture (think 20LPI) and then keep the circular shape of the WW tip at equal spacing for a symmetrical pattern. One could also come space this tip, then come in between with a small round tip
