Prazi attachment for circular saws. It turns your regular 7-1/4 inch circular saw into a true cutting monster. Instead of a modest 2-1/2 inches, you get the ability to saw up to 12 inches deep, and if you need a 45 degree oblique cut, you're welcome, as much as 8 inches. Installation of this attachment is simple. In just a minute, you turn your regular saw into a super tool. And regardless of what brand you have - Skil, Bosch, Makita, DeWalt or Craftsman - the Prazi will befriend most 7-1/2“ and 8-1/2” circulars without a worm drive. And there's no disassembly or assembly - just attach and you're done. The attachment allows you to make large cuts in one pass: no mistakes, no hassle with repeated passes, and it runs much quieter and smoother than a traditional chainsaw.
