Notes:	1. All the tool plates and die inserts/punches required nitrogen heat treatment & cryogenic process
	2. Tool plates & components required mirror finishing prior tooling shipment
	3. All the forming inserts required diamond paste polishing prior tooling assembly
	4. No sharp edges and corners allowed prior tooling assembly
	5. Above tool steels for all highspeed tool customers, unless other specified
