Perform heavy duty knurling with a CNC lathe to create a grip. These tools use knurls with smooth, rounded edges to press patterns into your material. Knurls are not included, except for internal knurling tools. Right-hand holders move from right to left toward the lathe chuck, and left-hand holders move from left to right away from the lathe chuck. Neutral holders cut in either direction.

Use internal knurling tools on the inside of holes and bores to reduce slippage between parts. They also improve adhesive bonding by creating more surface area as compared to a smooth surface.

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.
