Problem with tools

[Wintersky20]

I have some problems with "creation of tools" !

One of the problems that I have with my tool is this :

Spoiler

package wintersky20.ws20t.items;

import java.util.Set;

import com.google.common.collect.ImmutableSet;
import com.google.common.collect.Sets;
import com.jcraft.jorbis.Block;

import net.minecraft.block.material.Material;
import net.minecraft.block.state.IBlockProperties;
import net.minecraft.block.state.IBlockState;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Blocks;
import net.minecraft.item.ItemAxe;
import net.minecraft.item.ItemPickaxe;
import net.minecraft.item.ItemSpade;
import net.minecraft.item.ItemStack;
import net.minecraft.item.ItemTool;
import net.minecraft.world.World;
import wintersky20.ws20t.Reference;
import wintersky20.ws20t.ws20t;

public class ItemDrill extends ItemPickaxe {

    public ItemDrill(ToolMaterial material) {
        super(material);
        setUnlocalizedName(Reference.ws20Items.DRILL.getUnlocalizedName());
        setRegistryName(Reference.ws20Items.DRILL.getRegistryName());
        setCreativeTab(ws20t.CREATIVE_TAB);
        this.attackSpeed = 0.9F;
    }

    @Override
    public boolean canHarvestBlock(IBlockState state, ItemStack stack) {
        return true;
    }

    @Override
    public Set<String> getToolClasses(ItemStack stack) {
        return ImmutableSet.of("pickaxe", "spade", "axe", "shovel");
    }

    @Override
    public int getItemEnchantability() {
        return this.toolMaterial.getEnchantability();
    }
    
    
}
 

-> I can't enchnat the item in the enchanting table only in a anvil

->I can't brake the crafting table with this tool ( I mean , I can , but is taking me a long time to do ths)

-> And if i try to switch the extension with a ItemAxe , the i can't break redstone ores and obsidean !
