These coarse knurls cut a clean 14 lines per inch into steel with no slipping, and the 3/4" diameter is perfect for my tool rest setup. I’ve already ordered a second pair for another project.

The 14 lines per inch on these coarse diamond knurls give just the right grip for my small shop projects. I was surprised how cleanly they seat into the holder.

The 1/4" shaft hole fits snugly on my arbor with zero wobble, and the 3/8" width covers enough surface to make a clean pattern in one pass. These coarse knurls bite into mild steel without skipping, and the 14 lines per inch come out sharp and even. Just what I needed for a handle repair job.
