Knurled Designs: Adding Texture and Functionality to Your Product


In the world of manufacturing, aesthetics and functionality are equally important. That's why designers and engineers are always searching for new ways to make their products stand out and enhance user experience. One of the most effective and versatile methods is knurling. In this article, we'll explore the benefits of knurled designs and how they can elevate your products to the next level.

What is knurling?

Knurling is a manufacturing process that creates a pattern of small, raised shapes on the surface of a material. The most common shapes are diamond, straight, and helical, but other custom patterns can also be achieved. Knurling is typically done by pressing a tool with a knurled surface against the material as it rotates on a lathe. This creates an interlocking pattern that adds texture and grip to the surface.

Why use knurled designs?

Knurled designs offer several advantages over smooth surfaces. First and foremost, they provide better grip, especially when the material is wet or slippery. This makes knurled designs popular in tools, knobs, and handles where a firm grip is essential. Knurling also adds visual interest to the product, making it more appealing to customers. Furthermore, knurled designs can hide scratches, dents, and other imperfections on the surface, making the product look more polished and durable.

Examples of knurled designs

Knurled designs are commonly found in a wide range of products, from consumer electronics to precision instruments. For example, the volume knobs on a guitar amplifier are often knurled to make them easier to turn. Another example is the crown of a watch, which is often knurled to provide a better grip when adjusting the time. In manufacturing, knurled designs can be found in everything from machining parts to milling parts.

CNC machining and knurling

CNC machining is a popular method for creating knurled designs because it offers high precision and repeatability. With CNC machining, the knurling tool is controlled by a computer program, ensuring that each pattern is identical. CNC machining is also compatible with a wide range of materials, from plastics to metals, and can achieve custom patterns and sizes. This makes it an ideal choice for prototyping and low-volume production.


Knurled designs are a simple yet effective way to add texture and functionality to your products. They offer better grip, improved aesthetics, and can even hide surface imperfections. Whether you're designing a tool, a knob, or a luxury timepiece, knurled designs can take your product to the next level. With modern manufacturing techniques like CNC machining, it's easier than ever to incorporate knurling into your designs and create a product that stands out from the crowd.
