Grader Cutting Edges

Blades available in double bevel curved, double bevel flat, serrated or non-serrated.

Curved blades from 6″ and 8″ wide. Speciality blades from 10″, 13″, and 16″ wide.

The curved shape of the blades results in better material flow when used on graders and underbody plows.

Black Cat Curved Carbide Grader Blades are a superior choice for any low impact, high abrasion application.
The Inserted Carbide teamed with abrasive resistant impregnation (Carbide Inserted/Carbide Impregnated)
significantly extends the life of the parent material when used in applications where “face” wear is a problem.
The curved shape of the blades results in better material flow when used on Graders and Underbody plows.
Tungsten Carbide inserts result in a blade with extremely long wear life allowing for fewer blade changes and
an excellent resistance to “crowning” for applications that require a level grading operation.

Mining Grader Blades

  • Standard 16G/H/M and 24H/M Edges, 10” 13” and 16” Wide
  • Optional Thickness from 1” to 3”
  • 24H/M Edges in Standard 4’ Lengths or Optional 8’ Lengths
  • Tungsten Carbide Impregnation for Extended Wear Life in Abrasive Applications
  • Optional Threaded Holes Accommodate Lifting Eyes for Safer and Faster Installation
  • Serration can be Added to Flat or Curved Blades for
  • Increased Penetration and/or to Leave Fines on Surface
  • Blades can be Packaged in Kits Allowing for a Complete. Change-Out to be Stocked as One Item
  • Grader Scarifier Teeth

    Black Cat manufactures a variety of ripper/scarifer shanks and teeth that will penetrate tough material fast and rip thoroughly for easier material movement with the moldboard.

    Overlays And End Bits

    Black Cat overlay end bits help protect the moldboard from excess wear and extend the life.
    The Overlay also assists in extra wear protection and strength for the cutting edge and the moldboard itself.

    Reversible overlays are used with curved edges, and can be used twice to double the life.

    Scarifier Bits And Boards

    Black Cat grader bits

    Tungsten carbide-tipped cutting tools outlast steel blades and will save you time and money.
    Worn cutting tools may be replaced individually and independently of the blade section and bolts, without the need for special tools.
    Rotating Scarifier Bits are self-sharpening for more uniform wear and longer life.
    Cutting height is maintained as cutting tools may be rotated form position to position.
    Board systems are available as well.

    Black Cat scarifier bits are ideal for dirt and gravel road maintenance; hard-packed snow and ice removal;
    chip and seal road reclamation; tar sand road reclamation; spot asphalt milling; spreading loose material;
    mixing calcium chloride, magnesium chloride, or other dust suppressants.
