M2 Steel Ball Lock Regular Punches - Heavy Duty Tip O

This ball lock regular punch set is used in progressive and compound injection stamping tooling where stable alignment and controlled material flow are required at each press stroke.

In automotive and appliance wiring harness blanking, the ball-lock ejector retention supports consistent punch positioning across repeated cycles, helping reduce drift and misfeeds when forming thin metal sections.

For metric blanking and forming die sets, the Tip O geometry is suited for controlling deformation at the contact point, improving edge consistency while maintaining reliable point-to-shank engagement for repeatability.

• Ball lock retention helps keep the punch securely seated in the die system.
• M2 (heavy-duty) construction supports long runs where wear at the punch point is critical.
• Matched shank engagement improves stroke-to-stroke dimensional stability.

The heavy-duty variant is available in M2 steel (also offered as PS4). M2 is widely used for punch tooling because it balances wear resistance with moderate toughness; in practical terms, it offers improved life where the tip experiences repeated abrasion and sliding contact.

For typical M2 punch applications, the steel is commonly supplied in a hardened condition and is used for blanking/forming once the point and working surfaces are ready for service. The hardened state increases surface hardness, improving resistance to rounding and edge wear, but can reduce impact toughness if the tooling sees shock loading.

• M2 vs. PS4: choose M2 when maximum point wear resistance is the priority; select PS4 when you need an alternate steel availability/performance balance for your tooling requirements.
• Heat treatment: hardened tooling state is intended to provide stable hardness at the working surfaces during production.

Selection starts with the shank diameter D and overall length L to ensure proper guidance and retention in your holder and die block. This series supports D = 10 ~ 40 mm.

Next, match the point length L1 and tip geometry (Tip Shape O) to your cavity/core and the required penetration profile. Available point-length ranges include L1 = 10 ~ 19, 13 ~ 25, or 19 ~ 30 mm, and overall L = 63 ~ 125, 71 ~ 125, or 80 ~ 125 mm.

• Verify holder interface and ball-lock clearance for smooth seating and consistent stroke alignment.
• Check working clearances using P (1.5 ~ 12 mm) and W (1.5 ~ 14 mm), which influence the contact/contact-edge profile in the forming zone.
• Confirm service limits based on your press tonnage and alignment strategy; smaller profile dimensions may be more sensitive to misalignment.

Configurable: Tip Shape and Material are variable; D, L1, and L are selectable within the provided ranges.
