Thanks for all the feedback so far. My drill press is a Rexon 200A. Trying to find instructions for it. Doesn't seem like it turns very fast.

My understanding is that if you use a scissors knurler it doesn't put any lateral pressure on the bearings - that happens when you use the other kind of knurler which pushes towards the part.

Is anybody familiar with using these scissors knurlers that are fairly cheap on eBay?
