The ones supplied by Hemingway fit their kits, but they are not cheap, although they are the right size.

Must admit it was 2011 when I got medium from them. Wheels are 5/8" x 1/4". Might be worth a call though.

I do have to say this shows there are still some advantages to making your own knurling tool, even when cheap ones can now be obtained that do a reasonable job.

At least with a homemade one you can make it fit whatever stock bore sizes happen to be available to your area.

In other words, you're not necessarily stuck with a design that can't be altered easily.

I’ve bought 1/4″ bore knurling wheels from various sources and they all seem to be slightly different widths. I’d make my tool capable of taking spacer washers to take up the difference for the narrower wheels.

Some one with a surface grinder might be willing to whittle a set down.

Gloster tooling sell what your looking for. I have fitted HSS medium diamond knurls 3/4" x 1/4" wide x 1/4" bore to a knurling tool I have just made and they work fine. Cost was £12.60 delivered.

Apologies for resurrecting an old thread, but the info supplied (by me) above is incorrect.

The correct Hemingway wheels are 5/8" x 3/16" x 1/4" bore. It does seem a bit of an odd-ball size and they are not stocked in many places. Cromwell Tools do keep them but are rather expensive, but Hemingway does not keep much choice. Cromwell have them in Fine, Medium and Coarse versions.

Indeed. Hence I went with 1/4" width wheels. The arms are only 1/2" thick so you only have an 1/8" of steel either side in support, bit I've had no problems yet and it's been worked hard.

And because i'm a Cheap Charlie and had a surplus of 3/8" wide, brand name 1/4" bore wheels of different patterns, i made a jig and skimmed them down in my Stent T&CG – now that was fun. Not.
