Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is cut or rolled into the material.
The operation is performed for producing indentations on a part of a workpiece. Knurling allows hands or fingers to get a better grip on the knurled object than would be provided by the originally smooth metal surface. Occasionally, the knurled pattern is a series of straight ridges or a helix of "straight" ridges rather than the more-usual criss-cross pattern.
Knurling may also be used as a repair method: because a rolled-in knurled surface has raised-up areas surrounding the depressed areas, these raised areas can make up for wear on the part. In the days when labor was cheap and parts expensive, this repair method was feasible on pistons of internal combustion engines, where the skirt of a worn piston was expanded back to the nominal size using a knurling process. As auto parts have become less expensive, knurling has become less prevalent than it once was, and is specifically discouraged by performance engine builders.

In this video I'm making a big shaft with a knurled section in the middle. This footage is from a failed restoration video recorded in July 2021. I cancelled this restoration of an old and very rusty 25kg dumbell that was sent to me by a subscriber from Germany. I thought I could still share the footage of the making of this shaft, because it was very special to knurl from both sides with an overlap. I've never done or seen this before anywhere. One very critical point for a successful result is definitely the runout. The part has to run 100% true on both knurlings. Therefore the only way to achieve this was to turn the part between centers. As I don't have any lathe dogs in the shop I decided to fix the part with a dead center with a threaded shaft. Like that the part was running true and...

Welcome back to my manual machine shop. In this video series I’ll be making a much improved knurling tool from my current bump knurler setup. Rather than engineer this one from scratch I’m starting with the sensitive knurling tool kit from Hemingway Kits (not sponsored). The kit is based on the somewhat renowned vintage “Marlco” design and has a lot of advantages and nice features. This first video will focus on the arm assembly and I’ll be making heavy use of the mill and the rotary table. And of course a fair bit of lathe work with some unique setups will be needed as well so you know I’m excited for that! #inheritancemachining #machineshop #hobbymachinist Knurling Kit (unaffiliated)- https://www.hemingwaykits.com/HK1115 Patreon (Drawings) - https://www.patreon.com/inheritancemachinin...
