Direct Product Definition
A DIN 9861 Part 2 Type C round piercing punch.
The Universal Punch #571 is a precision round piercing punch for press tools used in piercing and cutting operations. The manufacturer catalog identifies applications including sheet, steel, non-ferrous metals, plastics, paper, and basic printed-circuit-board material.
The catalog provides Type C geometry, h6 fit/tolerance information, HSS and ASP30 material guidance, hardness ranges, finish details, and an optional HSS surface-coating note. The final production tool should be configured from the customer's required dimensions and application.

Application Selection
Start with the material being pierced and the required DIN geometry.
The #571 should be selected from the print and production requirement rather than from series number alone.
02
Confirm the geometry
Define the required d1 working/step diameter, d3 shaft diameter, d2 head/shoulder geometry, overall and step lengths, and the head dimension shown on the production drawing.
03
Select material & finish
Choose between the catalog-listed HSS and ASP30 options based on the application. If a surface coating is required, identify it during quotation.

Catalog Fit / Tolerances
Published h6 dimensional ranges.
Values below reproduce the #571 catalog table. Dimensions are shown in millimeters. Final tolerances should be checked against the current controlled drawing before manufacture.
Nominal diameter d1 — step
| Fit | Nominal range | Published lower deviation |
|---|---|---|
| h6 | 0.05–3.00 Ø | −0.006 mm |
| h6 | ≥3.00–6.00 Ø | −0.008 mm |
Nominal diameter d3 — shaft
| Fit | Nominal range | Published lower deviation |
|---|---|---|
| h6 | 1.50–3.00 Ø | −0.006 mm |
| h6 | ≥3.00–6.00 Ø | −0.008 mm |
Length callouts in the catalog: total l1 +0.5 mm; step l2 +0.05 mm. The catalog's ordering text lists d1, d2, d3, k, l1, l2, while the engineering drawing visibly labels the head-related dimension as h. Universal Punch engineering should resolve that legacy catalog notation before the ordering list is treated as a controlled manufacturing requirement.
Material Selection
HSS and ASP30 are the catalog-listed options.
Material selection should follow the work material, wear mechanism, production volume, tool geometry, and current Universal Punch manufacturing guidance.
High Speed Steel
The catalog describes HSS for high-strength or difficult-to-work materials and notes abrasion resistance, tensile strength, and heat resistance.
- Shaft: HRC 62–64
- Head: HRC 45–55
- Special surface coating available on request per catalog note
Powder-metallurgy high-speed steel
The catalog identifies ASP30 as a powder-metallurgy-manufactured high-speed steel and specifically notes increased life expectancy in applications such as piercing stainless material.
- Shaft: HRC 65–67
- Head: HRC 48–55
- Evaluate when application wear demands justify the material choice
Manufacturer Configuration
Build the #571 from the print—not assumptions.
Define the pierced feature
Provide the target hole/piercing geometry, tolerance, component print, and work material.
Specify punch dimensions
Identify d1, d2, d3, l1 and l2 from the applicable drawing, plus the head-related callout confirmed by engineering.
Select tool material
Identify HSS or ASP30, or request an application review when material selection is not yet established.
Define finish / coating
State whether a special coating or other finish requirement is part of the RFQ.
Confirm press-tool context
Provide machine, holder, die or press-tool information when it affects interface geometry or service conditions.
Confirm quantity & documentation
Include order quantity, required inspection documentation, drawing revision, and any special packaging or identification needs.
Piercing Punch Family
Choose the DIN / ISO geometry required by the tooling design.
The 2010 catalog groups #570 through #577 as the piercing and hole punch family. The individual series correspond to different DIN/ISO geometries rather than a simple good/better/best hierarchy.

Technical FAQ
#571 questions and direct answers
What is the Universal Punch #571?
The #571 is a DIN 9861 Part 2 Type C round piercing punch for press-tool piercing and cutting applications. The catalog lists sheet, steel, non-ferrous metals, plastics, paper, and basic printed-circuit-board material among its uses.
What materials are listed for #571?
The catalog lists High Speed Steel (HSS) and ASP30 powder-metallurgy-manufactured High Speed Steel.
What hardness is published for #571?
For HSS, the catalog lists shaft hardness of HRC 62–64 and head hardness of HRC 45–55. For ASP30, it lists shaft hardness of HRC 65–67 and head hardness of HRC 48–55.
What does the catalog say about #571 tolerances?
The published table identifies h6 ranges for d1 and d3. For d1, the lower deviation is −0.006 mm from 0.05–3.00 mm and −0.008 mm from 3.00–6.00 mm. For d3, the lower deviation is −0.006 mm from 1.50–3.00 mm and −0.008 mm from 3.00–6.00 mm. Current controlled-drawing requirements should be confirmed before manufacture.
Can HSS #571 punches receive a coating?
Yes. The catalog notes that HSS piercing punches can be treated with a special surface coating on request. The current coating selection should be confirmed during quotation.
Why does the catalog mention Type C+CA in one place and Type C on the #571 page?
The catalog table of contents groups #571 under DIN 9861 Type C+CA, while the dedicated #571 product sheet is labeled DIN 9861 Part 2 Type C. This page preserves the dedicated product-sheet designation and flags the broader table-of-contents wording for engineering verification rather than silently reconciling the two.
What should I submit for a #571 quote?
Send the print or drawing, dimensional requirements, work material, required punch material, quantity, machine or holder information where relevant, coating needs, and any inspection or documentation requirements.
Configure #571 from the actual tooling requirement.
Send Universal Punch the drawing, material, dimensions, quantity, production context, and any coating or documentation requirements so the current #571 configuration can be reviewed before quotation.
