M2 Steel Ball Lock Regular Punch Blanks - Light Duty

Q: Which shank diameter (D) range is supported for these metric ball lock punch blanks?

The specified D (shank dia.) range is 6 ~ 38 mm . Choose the value that matches your die set’s ball-lock seating interface to ensure stable retention and correct punch alignment.

Q: How should I choose the correct blank length (63–100 mm) for my die stack-up?

Select a Length within 63 ~ 100 mm based on required punch projection and clearance. Verify that the blank can fully seat in the ball-lock holder while leaving enough room for the stripper/guide components in your tooling.

Q: What material options are available in this series, and when would I prefer M2?

Material options listed are A2 , PS4 , and M2 . Prefer M2 when you want a higher wear-resistance punch blank for routine light-duty punching and improved edge retention under repeated cycles.

Q: Are these suited for standard metric die sets?

Yes. The metadata specifies metric die set compatibility, helping integrate the blank efficiently into standard ball-lock punch systems used for punching and blanking operations.

Ball lock regular punch blanks (M2 steel) in light duty design provide a reliable starting form for metric punching tooling. The ball lock retention geometry helps keep punches properly seated during production.

Product Guide

🏭Application Scenarios+

These light-duty ball lock punch blanks are used in metric punching and blanking tooling where consistent punch retention is critical. The ball-lock geometry helps keep the punch seated under repeated press cycles, reducing the risk of misalignment or ejection during production.

Common scenarios include:

Automotive and appliance sheet-metal parts: ideal for routine blanking stations in progressive or turret die sets, where punches see moderate loads and frequent indexing.
General fabrication die sets: suitable for making small- to mid-size features in mild steel and common sheet alloys using metric standards.
Die maintenance and modular upgrades: serves as a replacement blank in ball-lock punch systems to maintain repeatable fit without redesigning the die.

The M2 option in this variant offers a good balance of wear resistance and toughness for light-duty production runs and day-to-day punching applications.

🔧Material & Process Details+

This series offers multiple steel options—A2, PS4, and M2—to match different wear and toughness targets for punching. For the M2 grade, the material is commonly associated with AISI M2 high-speed steel family performance, supporting improved wear resistance at the punch tip.

M2: best suited when sliding wear and edge retention matter for repeated light-duty punching.
A2: a practical choice for more moderate wear environments, emphasizing toughness and shock resistance.
PS4: an alternative alloy option used for tooling performance where customers specify that grade for balancing durability and cost.

While the exact hardness (HRC) and specific heat-treatment route (e.g., quenched & tempered, nitriding) are not provided in the input data, these steels are typically delivered in a hardened state appropriate for punching tool service. Select the grade based on expected wear, cutting edge life, and press load profile.

📐Sizing & Selection Guide+

Select dimensions by matching the punch shank diameter and usable length to the ball-lock station geometry in your die set. The provided ranges for this series are:

D (shank dia.): 6 ~ 38 mm
Length: 63 ~ 100 mm

To size correctly, choose a blank where D matches the ball-lock bore and seating interface in your punch holder. Then confirm Length provides the required projection and clearance for the stripper plate or guide components so the punch can fully seat while maintaining safe stack-up.

Fit considerations: the ball-lock retention geometry is designed for stable seating, but your die build may require accounting for normal manufacturing tolerances between shank, holder, and ball-lock seats. If you are standardizing across a metric die set, use the same shank diameter family and consistent length selection to reduce assembly variation.

Frequently Asked Questions

Which shank diameter (D) range is supported for these metric ball lock punch blanks?+

The specified D (shank dia.) range is 6 ~ 38 mm. Choose the value that matches your die set’s ball-lock seating interface to ensure stable retention and correct punch alignment.

How should I choose the correct blank length (63–100 mm) for my die stack-up?+

Select a Length within 63 ~ 100 mm based on required punch projection and clearance. Verify that the blank can fully seat in the ball-lock holder while leaving enough room for the stripper/guide components in your tooling.

What material options are available in this series, and when would I prefer M2?+

Material options listed are A2, PS4, and M2. Prefer M2 when you want a higher wear-resistance punch blank for routine light-duty punching and improved edge retention under repeated cycles.

Are these suited for standard metric die sets?+

Yes. The metadata specifies metric die set compatibility, helping integrate the blank efficiently into standard ball-lock punch systems used for punching and blanking operations.

What does “ball lock regular” retention mean for tool stability during production?+

The ball lock retention geometry is intended to keep the punch properly seated during press operation. This supports repeatable performance by reducing seating slippage or ejection risk in a ball-lock punch-and-blanking configuration.
