VT machining offers CNC Reaming for A2 Tool Steel (UNS T30102 / 1.2363 / SKD12), typically supplied annealed or hardened. Air-hardening with very low distortion; tougher than D2.
CNC Reaming Notes for A2 Tool Steel
Reaming A2 Tool Steel gives H7 holes with a fine finish; stock allowance is set by hole diameter so the reamer cuts cleanly.
For estimating, a 100 × 100 × 10 mm block of A2 Tool Steel weighs about 0.79 kg.

Does CNC Reaming A2 Tool Steel require dedicated tooling?
Most A2 Tool Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is CNC Reaming A2 Tool Steel and how is it done?
CNC Reaming A2 Tool Steel refers to reaming finishes drilled holes to a precise diameter and smooth surface in a single controlled pass. Applied to A2 Tool Steel — wear-resistant and hardenable for tooling — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What surface finish is achievable on A2 Tool Steel with CNC Reaming?
Surface finish on A2 Tool Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Why is A2 Tool Steel a good choice for CNC Reaming?
A2 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Reaming. We tune the process to the alloy so the finished A2 Tool Steel machining part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for CNC Reaming A2 Tool Steel?
CNC Reaming prototypes for A2 Tool Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Reaming A2 Tool Steel?
Achievable tolerances for A2 Tool 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.
