Dual-Carbide Blade Accessories

MAG/500 x (1/2") thick Cover Blades are essential when operating Dual-Carbide Grader Blades in extremely abrasive conditions. Because the non-carbide portion of the Dual-Carbide blade is a much softer material, the wash within the front portion of the blade causes the bolt-heads to wear before all of the Carbide is consumed. Therefore, these extremely wear-resistant Cover Blades provide the additional wear needed to consume the entire amount of Carbide.
 
Users should know that it is not necessary to install these Face Cover Blade when a new system is installed... only when the bolt-heads are in jeopardy of containing the blade on the Grader moldboard. It is MHL's feeling that when the bolt-heads can no longer secure the Dual-Carbide Blades to the Grader, the MAG/500 Face Cover Blades should then be installed. With this procedure, we know of users where a set of the Cover Blades will last long enough to protect and give the necessary wear-life to (3-4) sets of Dual-Carbide Blades.
