you like to use a cavity or a hole in the center of
a brush to further tune your motor, this might just
be the easiest tool to use on the market. It will work
with upright or laydown AND Checkpoint brushes.
The tool comes with two bits to work with:
#53 (.0595") or 1.5mm and #49 (.073") or
The bits are finger operated, no power tools required.
Simply lay the brush in the slot, hold it down with
your thumb, select the bit size, insert it into the
hole & twist away for a perfectly centered hole
in the end of your brush. The pilot shaft on the bit
fits into the brush jig without wearing out the jig.
The brush tool is small so it will not take up valuable
space in your pit box.
