It was American luthier Harry Fleishman who came up with the idea back in the 90s. Back then, Harry did the whole process by hand. You can find his instructions in American Lutherie magazine #53.

I’ll be honest, even with this new tool of mine, semi hemispherical fretting still takes time, much more than regular fretting. But this neat diamond grinding tool does speed things up and make the results more consistent. The “rounding over” part of the job is far quicker.

I’ve been using this for the last year or so and it works really well. More accurate and quicker than any other way of doing it I’ve seen.

Now, there is a step you need to take before you even try semi-hemi fretting and that is to learn how to fret a neck so well that your frets require no levelling after they are installed. You can learn how to do that by buying the Michael Bashkin fretting course that Robbie O’Brien sells. Michael covers fretboard prep, fret installation and even covers how to do semi hemispherical fretting by hand. Since making the video Michael bought one the the semi hemi wheels, so his process has speeded up, but you’ll learn much of what you need to know from his video.

Back to the grinding wheel –

I use Evo Gold fretwire and have no signs of wear. The tool has not been tested with stainless steel fretwire. As we all know, SS wrecks tools far quicker, so expect the same if you intend to use SS frets.

The standard wheel fits 2mm wide wire. 3mm and 4mm wire are also possible. Ask.

The price is for the wheel and a mandrel to fit your drill press.

Run the tool at around 1400 – 1500rpm.

Pricing (including shipping) for a wheel and mandrel:

USA.    US$180

UK.    £130

EU.    €140

Australia.    AU$190+GST

Canada.    CA$225
