    Knurls

    Get a grip—pair these knurls with a knurling tool to form patterns on your workpiece to make it easy to twist, grip, and pull. Also known as full face or standard knurls, they have a consistent pattern with sharp unbeveled edges suitable for most uses. All knurls have a ground finish to make precise, clean marks. To form a diamond pattern—common for tool handles, knobs, and fasteners—machine your material with both a right- and left-hand spiral.
    M1 High-Speed Tool Steel—M1 high-speed tool steel knurls work well on most materials.
    M42 High-Speed Tool Steel—M42 high-speed tool steel knurls, also known as cobalt steel knurls, are ideal for hard materials such as stainless and carbon steel. They are harder and last longer than M1 knurls.
    Teeth per Inch—Teeth per inch (TPI) determines how fine your pattern is. The higher the number, the smoother, more closely spaced your pattern will be. A tool handle is usually knurled with 30 TPI. A precision instrument knob would require an 80 TPI.

    CNC Lathe Knurling Tools

    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.

    Knurling Wheel

    Tools for two knurling wheels press more consistent patterns into your material than single-wheel tools, which can push your material off-center. You can also create diamond patterns—common for tool handles, knobs, and fasteners—in one pass rather than two. To do this, just pair a right- and left-hand spiral knurl when you machine your material.

    Knurls for Long Lengths

    Keep these knurls whirling to form a wide grip, like on a barbell. Also known as axial feed knurls, they have a convex face that runs along your workpiece more smoothly than standard knurls. This curvature means less force on the edge of the knurl, for less friction and a longer life. To create a diamond pattern—common for tool handles—machine your material with both a right- and left-hand spiral.
    Made of M42 high-speed tool steel, these knurls—also known as carbon steel knurls—are ideal for hard material such as stainless and carbon steel. A ferritic nitrocarburizing (FNC) coating hardens the surface to protect against wear, corrosion, and warping. However, the hardness may damage brittle materials (such as cast iron and ceramics) and soft materials (such as plastic and brass).
    Teeth per Inch—Teeth per inch (TPI) determines how fine your pattern is. The higher the number, the smoother, more closely spaced your pattern will be. A tool handle is usually knurled with around 30 TPI. A precision instrument knob would require around an 80 TPI.

    Bump

    Swivel Bump

    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.
    Swivel Bump—Swivel bump knurling tools have three sets of knurls that you can rotate between: coarse, medium, and fine pitch.

    Scissor-Style Lathe Knurling Tools

    Image of Product. Front orientation. Lathe Tools. Scissor-Style Lathe Knurling Tools.
    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.

    Quick-Change CNC Lathe Knurling Tools and Holders

    Image of System. Front orientation. Contains Annotated. Lathe Tools. Quick-Change CNC Lathe Knurling Tools and Holders.
    Cut down on setup time for heavy duty knurling with this system of tools and holders. Each holder accepts multiple tools, so you can install the holder on your lathe once, then swap out the tool to switch tasks. Knurls are included with each tool. They’re made of heat-treated, high-speed tool steel for strength and shock resistance. A titanium nitride coating prevents wear.
    Teeth per inch (TPI) determines how fine your pattern is. The higher the number, the smoother, more closely spaced your pattern will be. A tool handle is usually knurled with 30 TPI.
    Angled Tool for Cutting
    Image of Product. Front orientation. Lathe Tools. Quick-Change CNC Lathe Knurling Tools and Holders, , Cutting.
    Angled tools position straight-patterned knurls at an angle to create a diamond pattern on the workpiece.
    Tools for cutting have knurls with sharp teeth that remove material. They’re used to create deeper, more precise patterns than forming tools, especially on harder materials.

    Pair these knurls with a quick-change knurling tool to add patterns to your workpiece for an improved grip.
    Forming—Forming knurls create shallow patterns on soft materials by displacing material. They have smooth, rounded teeth.
    Cutting—Cutting knurls remove material to create deeper, more precise patterns than forming knurls, especially on harder materials. They have sharp teeth.
    Teeth per Inch—Teeth per inch (TPI) determines how fine your pattern is. The higher the number, the smoother, more closely spaced your pattern will be. A tool handle is usually knurled with 30 TPI. A precision instrument knob would require an 80 TPI.

    Forming

    Press uniform, high-precision knurls into parts with minimal pressure. These tools are good for small-diameter or long parts because they use less pressure than one- and two-wheel knurling tools, which can bend the part. The adjustable scroll gear supports a range of workpiece diameters. The knurls have smooth, rounded teeth. They distribute pressure evenly to maintain quality and efficiency—even in high-volume production runs. Use them in CNC lathes, turret lathes, and automatic screw machines. Pair them with a holder (sold separately) to fit your lathe.
