...the tensile strength. Cracking can occur in some materials, and when using a hydrocarbon-based dielectric carbon pick-up may occur in steel workpieces, leading to a hard martensitic layer. Design: Used extensively for tool and die work, and particularly suitable for irregular slots and cavities and small holes with high aspect ratios. Leaves no burrs. Holes down to 0.05 mm can be formed, but an allowance has to be made of 0.......
