Harvest tool

[InternalError_]

How do i set the tool that is required to break the block?
BLOCK_ORE = new FFRegistryObject<>("ore_" + name(), blocks.register("ore_" + name(), () -> new DropExperienceBlock(BlockBehaviour.Properties.of(Material.STONE).requiresCorrectToolForDrops().strength(3.0F, 3.0F))));
This block for example cant be mined with any tools. 

 

I hope someone can help me

Put your cursor on a vanilla ore block and press F3 then look in the bottom right.

In particular the needs_xxx_tool and mineable tags.
