M2 Steel Extended Range Punches - Metric X Tip

Extended reach punches with an X tip profile are commonly used in injection mold tooling where a punch must reach deeper into the die while maintaining clean shearing. The extended length range (L 63–100 mm) helps support stable punch penetration in tightly packaged cavity layouts.

• Automotive and appliance parting-line trims: Use the X tip geometry to promote a controlled cutting action when space is limited, reducing risk of edge deformation during repeated production cycles.
• Connector and bracket insert-hold operations: The punch’s reach supports accurate forming of features in metric tooling, especially where the cavity/core spacing demands longer actuation length.
• General production tool-and-die stations: M2-based construction offers the wear resistance expected for frequent punch use, supporting consistent part formation across long runs.

This variant is suited to metric die making due to the defined shank diameter options (D: 40–63 mm) and standardized point length (L1 25–30 mm), enabling reliable fit to punch plates and guides.

This extended-range punch series is offered in M2 and A2 steels. M2 steel (high-speed steel class) is selected for wear resistance in production punching, helping maintain edge geometry under repetitive cutting loads. A2 is typically chosen when a balance of toughness and wear performance is needed, but its performance profile differs from M2 for high-wear applications.

For mold components like punches, the steel is commonly supplied in a heat-treated condition appropriate for cutting use, typically quenched and tempered for stable hardness before grinding to final dimensions. Final hardness is not provided in the supplied data; however, sizing and selection should assume a hardened cutting state suitable for punching wear rather than soft machining.

• Trade-off: Higher wear resistance steels help resist abrasion, while toughness determines how well the punch tolerates impact and load spikes.
• Manufacturing: Ground punch surfaces and precise tip geometry support repeatable alignment and clean cutting action.

To select the correct extended-range punch, match the required shank diameter (D) and overall length to the tool cavity/core spacing and punch plate thickness. This series provides D = 40, 45, 50, 56, or 63 mm and a fixed point length (L1) of 25–30 mm.

Next, confirm the needed reach using the fixed overall length L = 63–100 mm. Choose the specific variant that provides the required engagement without bottoming out in the tool set, especially for deep feature forming.

• P dimension: select from 20–39.95, 25–44.95, 30–49.95, 35–55.95, or 40–62.95 mm depending on where the punch tip must position relative to the die.
• W dimension: choose from 8–39.95, 9–44.95, 10–49.95, 11–55.95, or 12–62.95 mm to align with pocket/clearance geometry.
• R dimension: verify radius compatibility using 0.2–31.475 mm ranges.

Because the P/W/R values are given as ranges, ensure your CAD drawing selects the exact variant that meets your cavity/core clearance and maintains the intended fit at assembly. When guide systems are used, keep clearance consistent with the punch shank diameter selection.
