VT machining provides CNC Drilling D3 Tool Steel for customers who need accurate, repeatable D3 Tool Steel components. The machinability of D3 Tool Steel is machined in the annealed state, then hardened; carbide tooling preferred, so we set the operation up specifically for this grade.
CNC Drilling Capability for D3 Tool Steel
- Air/oil/water-hardening grades
- High wear resistance
- Hardenable to 58–64 HRC
- Tolerance to ±0.005 mm
Machining D3 Tool Steel with CNC Drilling
D3 Tool Steel behaves predictably under CNC Drilling once parameters are dialled in: machinability is machined in the annealed state, then hardened; carbide tooling preferred, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of D3 Tool Steel run consistently from one batch to the next.
Secondary Operations & Finishing
Finished D3 Tool Steel parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Why D3 Tool Steel?
D3 Tool Steel is chosen when a part needs what this grade offers — it is wear-resistant and hardenable for tooling. We confirm the grade and any temper or heat-treat condition with you before machining.
Design Tips for CNC Drilling D3 Tool Steel
We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in D3 Tool Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Drilling Tolerances & Surface Finish
For CNC Drilling, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
CNC Drilling Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every D3 Tool Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Drilling D3 Tool Steel
Customers order CNC Drilling D3 Tool Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

How clean are the edges produced by CNC Drilling on D3 Tool Steel?
Machined D3 Tool Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is the typical lead time and minimum order for CNC Drilling D3 Tool Steel?
CNC Drilling prototypes for D3 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 is CNC Drilling D3 Tool Steel and how is it done?
CNC Drilling D3 Tool Steel refers to programmed drilling produces accurately positioned holes, including deep and pattern hole arrays. Applied to D3 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.
Why is D3 Tool Steel a good choice for CNC Drilling?
D3 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Drilling. We tune the process to the alloy so the finished D3 Tool Steel machining part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Drilling D3 Tool Steel?
Achievable tolerances for D3 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.
