Diehl Steel has introduced Ready-Block EDM Blanks for EDM applications. The ready-to-use blanks are pre-hardened, squared and ground at Diehl Steel, eliminating the need for customers to machine and heat-treat them prior to use. They are available in many popular tool steel grades including in-stock AISI A-2 and D-2 (58-62 HRC).

Each block is first precision machined to a specific thickness, width and length, within +.010"/.020" tolerance. They are then hardened and tempered to a standard hardness. A starter hole is included at the customer's request.
