    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.
    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.

    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.

    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.

    Bump tools press against the side of the workpiece to align it with your lathe. They’re good for narrow knurling applications.
    Tools for forming have knurls with smooth, rounded teeth that displace material on the surface of your workpiece. They’re best for creating shallow patterns on soft materials.

    Straddle Tool for Forming
    Image of Product. Front orientation. Lathe Tools. Quick-Change CNC Lathe Knurling Tools and Holders, , Forming.
    Straddle tools clamp the workpiece from both sides, so the knurling pressure is absorbed by the tool rather than your lathe spindle.
    Tools for forming have knurls with smooth, rounded teeth that displace material on the surface of your workpiece. They’re best for creating shallow patterns on soft materials.

    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.
