Why Wire EDM Is Used on Hardened Die Inserts

Wire EDM cuts hardened tool steel without tool wear, holding ±0.01 mm on clearance angles and sharp internal corners that milling cannot reach.

keytrond machines non-standard parts from customer drawings across turning, milling, grinding, gear cutting and wire EDM. Where a drawing leaves a tolerance or material choice open, engineers propose a workable combination before quotation instead of guessing at the machine.
