Direct Product Definition
A DIN 9844 Type A round piercing punch for moving punch holding devices.
The Universal Punch #576 is identified on the dedicated catalog sheet as a DIN 9844 Type A round piercing punch for press tools used mainly in piercing and cutting perforations into sheet steel.
The catalog describes this Type A design for moving punch holding devices in the die. Its supporting-flange head geometry is intended to provide support at the punch holding plate while allowing appropriate clearance among the punch, punch holding plate and pressure plate.

Application Selection
Use #576 when the holder design calls for the DIN 9844 Type A support-flange configuration.
Selection should follow the component print, punch-holder design, required working diameter and material rather than the series number alone.
02
Confirm the holder geometry
Verify that the die and holding arrangement require the Type A supporting-flange geometry shown on the #576 drawing.
03
Confirm material & dimensions
Specify d1, d2, d3, d4, l1 and l2 together with the required material, quantity and any documentation requirements.

Catalog Fit / Tolerances
Published d1 h6 shaft tolerance.
The #576 catalog publishes h6 lower deviations for four nominal d1 shaft-diameter bands.
| Fit | Nominal d1 shaft diameter | Upper deviation | Lower deviation |
|---|---|---|---|
| h6 | 2.00–3.00 mm Ø | 0 mm | −0.006 mm |
| h6 | >3.00–6.00 mm Ø | 0 mm | −0.008 mm |
| h6 | >6.00–10.00 mm Ø | 0 mm | −0.009 mm |
| h6 | >10.00–16.00 mm Ø | 0 mm | −0.011 mm |
Table presentation: the diameter bands are shown here as non-overlapping intervals for readability; the published lower-deviation values are preserved from the catalog table.

Material Selection
HSS and ASP30 options published for the #576 Type A configuration.
High Speed Steel
The #576 catalog lists High Speed Steel for the DIN 9844 Type A punch.
- Shaft hardness: HRC 62–64
- Head hardness: HRC 45–55
- Catalog guidance describes HSS for high-strength or difficult-to-work materials.
Powder-metallurgy high-speed steel
The catalog also lists ASP30 and describes it as a powder-metallurgy manufactured high-speed steel.
- Shaft hardness: HRC 65–67
- Head hardness: HRC 48–55
- The catalog notes increased life expectancy in an example such as piercing stainless material.
