Semi hemispherical fret end grinding tool
What it is:
A diamond-coated steel wheel designed for one job: speeding up the “rounding over” phase of semi-hemispherical fretwork. It’s based on Harry Fleishman’s original hand-done method from the 90s—refined for modern builders who want consistent, pro-grade results without the grind. Literally.
Why you need it:
Semi-hemi fretwork looks and feels incredible—but let’s be honest, it’s slow. Even with this tool, it still takes more time than standard fretting. But it drastically speeds up the shaping process and makes results far more consistent. The “rounding” step, which usually drags, becomes smooth, fast, and repeatable.
What you get:
- Diamond-coated steel wheel with a machined groove sized for most common fretwire (2–2.7mm standard, 3mm and 4mm on request).
- Runs at 1450–1500 RPM on a drill press. It’s too heavy for handheld drills.
- Works great with Evo Gold fretwire. Stainless steel will wear it faster, but users have reported no complaints.
Arbor options:
- Standard arbor: 1/2″ hole, 1/4″ shank. Pressed/stamped—not perfect, may have minor vibration or wobble. Fully usable, but less smooth.
- Heavy-duty arbor: 16mm hole, 1/2″ shank. Precision-turned and rock solid. If you want the best experience, this is it.
Use case tip: If you’re using this a couple times a year, the standard works fine. If you’re building regularly or care about the feel—go heavy-duty.
Why trust it:
I’ve used this tool on my own builds for the last few years. It’s faster and more accurate than anything else I’ve tried. This isn’t a gimmick—it’s a time-saver that gets the job done better.
Even Michael Bashkin (whose fretting course is excellent and teaches this method by hand) has upgraded to using this wheel. If you’re not confident with fretboard prep yet, his course (sold via Robbie O’Brien) is where to start. You’ll learn everything from install to semi-hemi by hand.
