An 80-grit abrasive ball on a 1/4 inch shank, for controlled shaping of boot shells and liners in a rotary tool.
The 1 inch head is the point: it reaches into the tight areas of a shell where a larger burr cannot go, and it removes material in a controlled way rather than gouging.
- 80-grit abrasive for consistent cutting
- 1" × 1" head for tight areas
- 1/4" shank fits professional rotary tools
- For shell and liner shaping
Grinding is subtractive and permanent. Material cannot be put back, so the rule is to remove less than you think and check the fit repeatedly. Most over-grinding happens in the last thirty seconds, when it already nearly fits.
Grind or press? A boot press pushes the shell out without removing material, which is reversible and usually the better first move. Grinding is for places a press cannot reach, or where the shell needs genuine clearance rather than a bump.
Workshop tooling. If you have a fit problem rather than a tooling one, that is a job for a bootfitter.
