I am new to making mods and I made a few tools and items and they work fine, however, i cannot figure out how to set the repair material for the tools here is what i have. Also here is the src if you need more: https://github.com/Vortron-96/Tmod/tree/275b932abeb8728b1fa498c6994ed9f1d8eb8e64/src/main

package sx.root.tcraft.tmod.materials;
 
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraftforge.common.util.EnumHelper;
import sx.root.tcraft.tmod.tmod;
import sx.root.tcraft.tmod.init.ModItems;
import sx.root.tcraft.tmod.util.RegistryHandler;

 
public class CustomCobalt {
	
    public static final Item.ToolMaterial Cobalt = EnumHelper.addToolMaterial(tmod.MODID + ":" + "Cobalt", 4, 1200, 5.5F, 4.5F, 9).setRepairItem(new ItemStack(ModItems.alloyiron));
    public static final Item.ToolMaterial AxeCobalt = EnumHelper.addToolMaterial(tmod.MODID + ":" + "AxeCobalt", 4, 1200, 5.5F, 8.0F, 9).setRepairItem(new ItemStack(ModItems.alloyiron));
    public static final Item.ToolMaterial SpadeCobalt = EnumHelper.addToolMaterial(tmod.MODID + ":" + "SpadeCobalt", 4, 1200, 5.5F, -1F, 9).setRepairItem(new ItemStack(ModItems.alloyiron));
    public static final Item.ToolMaterial SwordCobalt = EnumHelper.addToolMaterial(tmod.MODID + ":" + "SwordCobalt", 4, 1200, 5.3F, 4.5F, 9).setRepairItem(new ItemStack(ModItems.ingoturmomium));
    
}

It has been a while since I have done anything in 1.12.2, but you only need to specify the material your items will be made of once. For each item you create, you just specify the 'Cobalt' where toolMaterial is required.
