Welcome to Jasper Tools
 
Jasper Tools

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.

New Pro Series Circle Guides!!

Our new Pro Series Circle Guides are manufactured in virtually unbreakable polycarbonate. All Circle guides are available in the Pro Series.
