DMC Wear Parts is proud to be an official KENNAMETAL parts dealer. Our scarifier blades and accessories are effective road grading solutions that outlast traditional steel blades. Scarifier blades maintain an even cutting height by allowing the individual carbide-tipped bits to rotate for uniform wear and longer tool life. The ability to swap individual bits means that they can be quickly moved from position to position, without removing entire blade sections, to prevent crowning that can occur with traditional grader blades.

Scarifier Blades & Boards
Kennametal’ scarifier blades are easier to use and more versatile than competitive systems. The surface engagement angle of the cutting tools is preset for optimum tool rotation, ease of use, and performance. Kennametal scarifier blades are available in three different styles that are designed to perform optimally in a range of ground conditions:
Standard-Duty Blades — Ideal for light-use road grading in average conditions and applications.
Heavy-Duty Blades — Generally ideal for road grading in most conditions and applications.
Severe-Duty Blades — Ideal for grading in extreme road conditions and applications. These scarifier blades feature a 6″ (152mm) blade width instead of the 5″ (127mm) width of standard-duty and heavy-duty blades. This provides more clearance between the toolholder blocks on the back of the blade and the “frog” of the moldboard. The severe-duty also include extra-heavy welds to reduce block breakout from the blade.
Scarifier Blade Chart & Ordering Information
NOTE: Kennametal recommends the use of Grade 8, Number 3 head-plow bolts and nuts when installing blades.

Scarifier Cover Blades
Optional cover blades provide exceptional wear resistance and superior protection of the main blade body when the scarifier system is operating in extremely abrasive conditions or when carrying heavy debris loads on the moldboard.
Cover blades attach easily through existing bolt holes on the blade using bolts that are .750″ (19mm) longer than the traditional bolt used to attach the blade to the moldboard.

Customer Testimonial
“From an operators standpoint conditions are always changing and with the Borox blue steel you have the ability to adapt to different conditions by switching between different cutting-edge styles and thicknesses easily. From a shop foreman standpoint less down pressure to do the job means less wear and tear on the machine, which translates to savings in the long run!”
