Joint Sealant Removal – Cutter Blade

(1 customer review)



SIZES: 4-1/2″, 6″, 7″, 8″, 9″, 12″

Cuts through hard and softer joint sealant – Without melting the sealant.

For Use On:

  • Walk Behind Saws
  • Hand Held Angle Grinders – Variable speed models are highly recommended (picture, right).
  • High-Speed Cut-Off Saws
  • Hot Rod Saws

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’ll 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.

    Stellite Cutter - Joint Sealant Removal Blades.

    Without exaggerating, we cut over 1 mile of joint sealant using the 6″ blade. The only reason why I’m purchasing another one is one of its teeth fell off, but that same blade is still going using only 3 teeth!

    9" Hybrid Hot Rod Saw. Complete blade visibility & dust control for both crack chasing & saw cuts ~ 2-3/4" depth-of-cut.

    Our 1st purchase was (2) of the 12″ and (3) of the 7″. We got several thousands of feet from the 12″ blades and over 1000 feet with the 7″. For now on we’re going with the 20 Diamond Deal and the Hot Rod Saw (right).

    Removing “soft” joint sealant at a General Electric warehouse: The sealant was of “bubble gum” viscosity. With all other removal methods, it was taking 1 minute to remove 6″ inches of sealant. With the Stellite blade, productivity increased to 6 feet per minute. Additionally, the blade left the joint’s inside edge clean; ready for resealing.

    How Do You Keep the Blade Cutting so Cool?
    I cut over 1,200 feet and the blade doesn’t get hot! The inside edges are clean and the blade still looks new!

    What the contractors are saying about the Stellite Cutter Blade

    Phenomenal – Night and day productivity versus 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.

    Fast ~ Very, Very Fast Slicing

    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 . . .

    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.
