• For use on standard handheld angle grinders and walk-behind saws.
  
  

• Slices or removes joint sealant from the inside edge of expansion joints without melting the sealant - including hard, soft and pliable sealants.
  
  

• As the blade is slicing through the sealant, the inside edge of the joint is  completely scraped clean with one pass of the blade . . .
  
  Any excess sealant still remaining is easily "touched-up" by lightly cutting into the concrete.
  
  A new and cleaning inside edge is exposed, assuring you of proper adhesive bonding of the new sealant to freshly exposed concrete.

How effective is the Stellite Cutter Blade at not melting the sealant?  Try This:  Slice through long strips of sealant - straight down through the center of the sealant and see for yourself how the sealant material (hard or soft) does not melt.

You've tried similar blades before and the diamond chips broke or fractured from the blade's metal core?  Try This:  Cut directly into the inside edge of the concrete joint and the Stellite® Cutter Chips will not break!  Though it isn't the design of the blade to do so, the design of the blade enables it to overcome a wide assortment of difficulties and abuses that are typically encountered on a jobsite - including the removal of joint sealant when concrete or mortar is "directly beneath" the sealant (instead of the joint being open-ended or filled with backer rod).
