Technical FAQ

Q: Are these inserts original or replacements?

A: We supply 100% genuine original inserts from brands like Sandvik and Iscar. We also offer our own high-performance BEYOND brand for cost-conscious workshops.

Q: Can I use one insert for both Steel and Stainless?

A: While "General Purpose" grades exist, we recommend dedicated grades for Stainless (like IC907 or GC2025) to prevent work hardening and edge wear.

Q: Do you offer bulk discounts for factories?

A: Yes. For orders over 50 boxes, please contact our B2B sales department for specialized pricing and tailored logistics.

Material Selection Pro-Tip

Always check the "Workpiece Color Code" on the insert box: **Yellow (P)** for Steel, **Blue (M)** for Stainless, and **Red (K)** for Cast Iron. Matching the coating to the material is the fastest way to double your tool life. **BEYOND CNC** - Your Industrial Tool Partner.
