Makita 13.5 Amp, Variable Speed, Long Life / High Performance Grinder.For Use On:

  • Walk Behind Saws

  • Hand Held Angle Grinders - Variable speed models are highly recommended (picture, right).

As effective as the blades are at slicing through sealant  without melting it, simply by lowering the RPM's on a variable speed angle grinder (or going just above neutral) on gas walk behind saws) you naturally reduce friction heat to further help improve or prevent the blade's effectiveness at slicing through longer sections of sealant without melting the sealant.

Harden stellite cutters slices along the inside edge of concrete and masonry expansion joints without having to go back with a wire brush to clean a straight edge:

  • As the blade slices along the joint's inside edge, the sealant is completely scraped clean with one pass of the blade . . .

  • Any excess sealant that may be inside a jagged edge can easily be removed by lightly cutting into the concrete using the Stellite Blade.

End Result:  New, clean inside edges are exposed - assuring you of proper adhesive bonding of the new sealant to fresh exposed concrete.

How Do You Keep the Blade Cutting so Cool?

Specifications / Features

Thermally Stable Stellite® Cutters

  • Resists high temperature heating
  • Maintains their sharp cutting edge
  • Harden, high temperature cutters keeps the blade from dragging - preventing friction heat

Precision Shaped & Fitted Chip:

  • High Pressure, High Temperature (HPHT) - Solid Stellite® Cutters
  • Precisely made, shaped and fitted to resist friction heat build-up
  • Cutter maintain their sharpness to slice through hard and soft joint sealant instead of grinding it . . .

Maintains Sharp Slicing Edge

  • Utility knife blades and diamond blades wear prematurely.
  • Diamonds round-over and grind (they do not cut).  Hence, when a diamond blade grinds it creates friction heat which causes it to instantly melt the joint sealant.
  • The harden cutters on the Stellite Blade do not round-over which keeps the sealant from melting.



Slice through Hard Polyurea and / or Soft Urethane

  • Cutter Chips Maintain Their  Sharp Edge

  • Sealant Material Does Not Melt

  • Cutter Chips Will Not Prematurely Fracture

- What the contractors are saying about the Stellite Cutter Blade -

********** Testimonial  **********

"Phenomenal - My guys say they're better than using a FEIN Caulk Cutter"

"Completely removed the sealant - we cut down both sides of the joint and pulled-out long strips of sealant.  The sealant was completely removed - we didn't have to go back and clean the joint's inside edges  -- well done and thank you."

" . . . used it on sealant that was very gummy (we think they forgot to add the hardener to it).  The blade worked far better than a Caulk Cutter or wire wheel."

Masonry Restoration Contractor, Chicago, IL


"Extremely Productive - After we cutout the sealant we immediately were able to install the new sealant.  The inside edges were completely  free from the old joint sealant and new concrete was exposed for proper bonding of the new joint sealant - the joint was completely prep'd and ready to go . . ."
