As a general guide, these are the tool steels and materials most commonly specified for press tooling. The exact grade for your die is selected based on the material being formed, production volume and required die life — confirmed in writing at the quotation stage.
| Material | Typical Hardness (post heat-treat) | Typical Application | Why It's Chosen |
|---|---|---|---|
| Mild Steel / EN8 | Unhardened, ~180–220 HB | Fixtures, holder blocks, low-cycle tooling | Economical where wear is not the limiting factor |
| EN31 (Bearing Steel) | 58–62 HRC | Guide pillars, bushings, wear plates | High wear resistance, dimensionally stable |
| D2 Tool Steel | 58–62 HRC | Blanking, piercing & trimming punches/dies | Excellent wear resistance for long production runs |
| D3 Tool Steel | 58–62 HRC | Heavy blanking/piercing, abrasive materials | High compressive strength |
| H13 Hot-Work Steel | 48–52 HRC | Deep-draw dies, hot-forming tooling | Toughness & thermal fatigue resistance |
| HSS (High-Speed Steel) | 62–66 HRC | Fine-blanking, high-precision punches | Superior edge retention at high hardness |
Every die starts with a DFM (Design for Manufacturability) review of your drawing, followed by in-house tool design, CNC roughing and finishing, and EDM wire-cutting for complex profiles and tight-clearance punch/die details. Components are then heat-treated, precision-ground, and assembled on hardened guide pillars and bushings.
Before any die leaves our tool room, it goes through a full trial run on press — dimensions checked on CMM/profile projector against your drawing — the same discipline shown in our Guide-Pillar Die Set and Trial Run reference examples above.
Feasibility, material and tolerance check before quotation.
In-house design through to wire-cut finishing.
Hardening, precision grinding, guide-pillar assembly.
CMM-checked sample approved before sign-off.
Full 8-stage manufacturing & quality-checkpoint detail on our Quality & Certifications page.
Tool steel components are hardened and tempered to the target hardness for their material grade and duty (see material table above) — hardening develops wear resistance, tempering restores toughness so cutting edges resist chipping in service.
Verified, not assumed: hardness on hardened components is checked in-house with our Rockwell hardness tester as part of our standard inspection process — not left to the heat-treatment vendor's word alone.
General linear and angular tolerances on machined die components follow ISO 2768 unless your drawing calls out tighter, part-specific tolerances — the same standard applied across all our machined and pressed work.
Per ISO 2768, medium/fine class unless specified otherwise on drawing.
[Confirm — typically a precision sliding fit; specify class per die set]
[Confirm — set per material type/thickness at design stage]
[Confirm on a per-drawing basis]
Exact fits and clearances are engineered per part — confirmed in writing before tooling build begins.
As a general guide, forming and blanking surfaces are typically finished in the region of 0.2–0.8 µm Ra — smoother surfaces reduce material galling and drag, extending both die life and the finish quality of the part being formed. Surface finish is measured in-house with our surface roughness tester as part of standard inspection.
Die life is a function of material hardness, the workpiece material and thickness being formed, cutting-clearance accuracy, lubrication and maintenance regime. Cutting edges are typically reground periodically to extend service life well before a die needs full replacement.
[Confirm — typical strokes/cycles before regrind is required, by die type and material formed, if you'd like this published]
Dies are designed to your press's bed size, shut height, stroke and tonnage — mechanical or hydraulic press, or CNC press brake for bending tools like our 2-metre V bending die. Share your press specification (or the press make/model) at RFQ stage for an exact-fit design.
Reverse-engineering an existing part or a worn die is a core capability, refined over 40-plus years in the tool room — send the physical sample or worn tool.
A die built for your part is billed separately and owned by you, though it stays housed and maintained at our facility for the life of the program unless dispatch is requested.
Ask us about a regrind schedule or spare-punch supply for existing dies — structured around your production calendar.
Design to delivery under one roof: in-house tool design, CNC machining and EDM wire-cutting for complex profiles, applied across Automotive, Electrical, Railway, Appliances and general industrial engineering work.
Bring us a drawing, a sample part, or a worn die — we'll advise feasibility, tolerance achievability and lead time before you commit to a PO.
Every progressive die, deep draw die and press tool order follows the same disciplined workflow — the same one shown on our Pressed Parts, SPM and Hammer Mill Screens pages, because it's the backbone of quality across every product line at Precimax Engineers.
Your drawing, sample part or worn die is reviewed for feasibility, tolerance achievability and manufacturability (DFM) before a quotation is issued.
In-house die design — station layout, guide-pillar arrangement, punch/die clearances and press-fit specification — engineered around your part and your press.
Tool steel grade (D2, D3, H13, HSS, EN31) selected against the material being formed, production volume and expected die life required.
CNC roughing and finishing, EDM wire-cutting for complex profiles, heat treatment, precision grinding and assembly on hardened guide pillars and bushings.
First article inspection on CMM and profile projector, hardness verification and a full trial run on press before the die is signed off.
Export packing with dimensional inspection report, Certificate of Conformance and Material Test Certificate, shipped to your destination port or facility.
As a die manufacturer in India with an established export track record, Precimax Engineers ships progressive dies, deep draw dies and press tools to OEMs and buyers across the USA, Europe, UK, Canada, Australia, the Middle East and Southeast Asia. Every export shipment is packed to withstand sea freight and handling, with documentation prepared for customs clearance at the destination port.
Export packaging, Certificate of Origin, commercial invoice and packing list are handled as standard; third-party pre-shipment inspection (SGS, Intertek, TÜV) can be arranged at your cost where your import process requires it.
Every die order runs through the same eight-stage discipline — RFQ & DFM review, in-house design and build, first article inspection on CMM, incoming material inspection, production run, in-process patrol inspection, final dimensional check, and export packing with full documentation.
See our full Quality & Certifications page for ZED Bronze certification, ISO standards followed, and PPAP/APQP support for automotive buyers.
Yes — reverse-engineering a part or a worn die from a physical sample is a core capability, refined over 40-plus years in the tool room.

A dimensional inspection report, Certificate of Conformance and Material Test Certificate as standard; third-party inspection (SGS, Intertek, TÜV) can be arranged at your cost on request.
Ask us — we can structure a regrind schedule or spare-punch supply around your production calendar for dies we've built or dies we reverse-engineer from your worn tool.
Lead time depends on die complexity, number of stations and material grade — confirmed in writing at the quotation stage, typically issued within 3–5 working days of receiving your drawing.
Share your part drawing and production volume — we'll quote feasibility and lead time.
