Product Guide
Application Scenarios+
These straight regular punches are used in punch-and-die tooling where repeated, accurate blanking is required, such as in progressive die stations for producing metal inserts and brackets. The straight geometry supports stable positioning in punch holders and die assemblies, helping maintain consistent alignment during each stroke.
In connector and bracket manufacturing, intermittent wear from friction and abrasive chip contact can shorten tool life. The XNAP coating on this metric punch variant is suited for these conditions because it improves abrasion resistance and supports reliable performance across production runs.
For engineers standardizing tooling libraries, this metric configuration is designed to match practical program setups and documentation workflows. The fixed L (length) range of 50–100 mm and P dimension 3–16 mm make it easier to plan compatible layouts for punch sets and corresponding die blocks.
- Progressive blanking of metal components using punch-and-die stations
- Applications with intermittent friction/abrasion that benefit from coating durability
- Tooling documentation standardization with metric punch programs
Material & Process Details+
The provided specification data identifies this punch as a metric straight regular punch with XNAP coating, supplied in a Dayton LAMINA standard format. However, the exact base steel grade, pre-heat treatment condition, and final hardness value are not included in the input parameters, so material hardness (HRC), toughness, and specific heat-treatment steps cannot be stated with accuracy.
What can be supported from the available data is the functional role of the XNAP coating: it is intended to enhance abrasion resistance and reduce the impact of friction-related wear in punch-and-die contact zones. When selecting between differently coated or uncoated punches, note that coatings typically trade some cost and surface prep requirements for improved wear life under repetitive cutting and sliding contact.
- XNAP coating: focuses on abrasion resistance and friction-related wear reduction
- Base material grade and HRC: not specified in the provided data
Sizing & Selection Guide+
To select the correct straight regular punch, start by matching the L (Length) = 50–100 mm to the required protrusion and support length in your punch holder and die setup. Use the intended die engagement depth and holder clearance to ensure the punch reaches the needed cutting interface while remaining properly guided throughout the stroke.
Next, verify the P dimension = 3–16 mm against your punch set geometry requirements (for example, how the punch interfaces with the holder seat or how the assembly is constrained). If the punch set is designed around a fixed P envelope, selecting outside the 3–16 mm range can cause poor fit or alignment issues.
- L selection: choose within 50–100 mm to suit required working length
- P selection: choose within 3–16 mm to match holder/assembly constraints
- Tolerance/fit: confirm allowable clearances in the punch holder and die block drawings, since tolerance values are not provided here
Frequently Asked Questions
What are the available size ranges for this straight regular punch (L and P dimensions)?+
This variant specifies L (length) = 50–100 mm and P dimension = 3–16 mm as fixed ranges. Ensure the chosen L value provides the required working length in your holder and die engagement.
Why choose an XNAP-coated metric straight punch for punch-and-die applications?+
The XNAP coating is intended to improve abrasion resistance and help manage wear driven by intermittent friction in punch-and-die contact areas.
This is especially relevant for production tooling where tool life is reduced by abrasive chip contact and sliding wear.
How does the straight punch geometry affect alignment in a punch set or die assembly?+
The straight regular design is made for consistent alignment in punch sets and die assemblies. In practice, that stability helps maintain predictable cutting conditions across repeated strokes.
When selecting dimensions, keep within the specified L (50–100 mm) and P (3–16 mm) ranges to avoid misfit.
Are the base steel grade and hardness (HRC) specified for this XNAP-coated punch?+
The provided product data does not include the base steel grade, hardness value (HRC), or the exact heat-treatment state. Only the coating designation (XNAP) and the dimensional ranges (L 50–100 mm, P 3–16 mm) are explicitly stated.
If you require HRC or material confirmation for your tool qualification, request the full material certs from the supplier.
Can this punch be used across different compatible punch programs, or is it tied to a specific tooling layout?+
The description indicates a Daytona LAMINA standard formatting intended to support streamlined part handling across compatible punch programs. However, fit and performance still depend on matching the required L (50–100 mm) and P (3–16 mm) dimensions.
Always validate compatibility against your punch holder and die block interface drawings.
