VT machining offers CNC Tapping for NAK80 Mold Steel (Daido NAK80 (pre-hardened)), typically supplied pre-hardened. Mirror-polishable pre-hardened steel with very uniform hardness.
CNC Tapping Notes for NAK80 Mold Steel
NAK80 Mold Steel is tapped with cut taps (spiral-point for through holes) and controlled rigid-tapping speed; thread milling is used where tap breakage would be costly.
For estimating, a 100 × 100 × 10 mm block of NAK80 Mold Steel weighs about 0.78 kg.
Starting Parameters for CNC Tapping NAK80 Mold Steel

Why is NAK80 Mold Steel a good choice for CNC Tapping?
NAK80 Mold Steel is mold-grade, polishable and hardenable, which makes it well suited to CNC Tapping. We tune the process to the alloy so the finished NAK80 Mold Steel machining part meets your dimensional and functional requirements.
Can VT machining make custom NAK80 Mold Steel parts to my drawing?
Yes. NAK80 Mold Steel machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What tolerances can you hold for CNC Tapping NAK80 Mold Steel?
Achievable tolerances for NAK80 Mold Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on NAK80 Mold Steel with CNC Tapping?
Surface finish on NAK80 Mold Steel is controlled to your specification; we confirm the achievable Ra against your callout.
