Press a grip into your workpiece using your manual lathe. These tools use knurls with smooth, rounded teeth to form grooves on your material. Upon contact with your material, the tool head adjusts to center the knurls for a consistent pattern. Use left and right-hand spiral knurls together to create a diamond pattern—common for tool handles—in one go. When your knurls wear out, you can pop them out and replace them. You can also swap the included spiral knurls for straight ones.

Pair these knurls with a quick-change knurling tool to add patterns to your workpiece for an improved grip.

Knurl material without straining your lathe. Also known as straddle-type knurling tools, these tools pinch both sides of your workpiece to balance out knurling pressure rather than transfer it to your spindle. Use them on soft materials to form patterns into your workpiece for a better grip. A left- and right-hand spiral knurl comes installed, so you can form a diamond pattern—common for tool handles—in one go. When you need to replace a knurl, switch it out without removing the tool from the machine. These tools can be flipped to be used in either a right-hand or left-hand orientation. Right-hand holders move from right to left toward the lathe chuck; left-hand holders move from left to right away from the lathe chuck.

Teeth per inch (TPI) determines how fine your pattern is. 21 TPI will create a coarse diamond pattern suitable for tool handles around _3/4" in diameter.
