Since 1998, Jasper Tools has been designing and manufacturing high quality
router accessories. Our patented calibrated circle guides have become the
standard for making exact circular cuts without a trial. They have been used for
making precision circular cuts for speakers, flush mounting speakers, small
acoustic ports, lazy susans, circular tabletops, guitars, rockets, telescopes, clocks
and many other applications that require circular cuts.
We also manufacture router base plates that convert the base of many routers to
receive Porter Cable style guide bushings.
Our Butterfly Template is designed for repairing damaged furniture or adding a
decorative inlay to new furniture.
