Slanted hammers and dies, angle at tensioning side, hammer or press

		die, die holder The “Feuerbacher tensioning key” in standard versions has angels of 5° and 15°. Other versions are available if necessary for special applications. The difference between the hammer / press-side should not be less than 5° by using in dies. The smallest possible slant on the anvil bed is 8° and on the die side 3°. .
		small drop-forge blocks, inserts For small drop-forge blocks and especially for die inserts in anvil caps, it is possible to use a 0° slant on the die side. In this case the difference between both clamping surfaces should not be less than 10°.
