FAQ

Frequently Asked Questions

Find quick answers about tool steel CNC machining, material grades, heat treatment, finishes, and production requirements.

We commonly machine D2, A2, O1, H13, and S7 tool steel, with other grades available based on project requirements.

D2 offers higher wear resistance and hardness, while A2 provides better toughness, dimensional stability, and resistance to chipping.

Yes. Tool steel parts can be heat treated after machining to achieve the required hardness, wear resistance, and mechanical properties depending on the material grade and application.

Typical machining tolerances can reach ±0.01 mm. Final tolerances after heat treatment depend on part geometry, material condition, distortion, and any required secondary grinding.

Yes. Material certificates can be provided upon request. Please specify any certification or traceability requirements when requesting a quote.

Available finishes include black oxide, nickel plating, polishing, and as-machined finishes depending on your requirements.
