Ball Lock Regular Punch Blanks - Heavy Duty Metric

Ball lock punch blanks are used as the working shank in production injection mold tooling where punches must index reliably and resist movement under repeated load. In typical setups, the blank is installed into a compatible punch holder using a heavy duty ball-lock retention interface, helping maintain alignment during cavity/core forming operations.

• Automotive connector and bracket tooling: Use these blanks when high repeatability is required for forming features such as through-holes or fine detail prep, especially where cycle-to-cycle positioning stability reduces scrap.
• Consumer electronics housings: The metric shank configuration supports straightforward integration with common tooling standards, reducing setup friction and improving maintenance efficiency.
• Industrial parts and housings: Their heavy duty retention geometry is suited for longer production runs where consistent punch seating improves forming consistency.

Choose the heavy duty metric variant for secure retention and compatibility across metric punch applications, with shank diameter D in the 10–40 mm range and lengths L up to 125 mm.

The provided product data does not specify a steel grade, hardness (HRC), or heat treatment state. As such, material properties like wear resistance, toughness, and heat treatment (e.g., nitriding, quench & temper) cannot be stated reliably for this exact variant.

• Material grade: Not listed in the specification provided.
• Hardness (HRC): Not provided.
• Heat treatment: Not provided (cannot confirm pre-hardened vs. quenched & tempered vs. nitrided).

When validating performance for your forming load and abrasive conditions, request the material certificate for the specific part/heat batch corresponding to series code 250000001783. Compare candidates by confirming hardness targets and surface treatments that match your wear and shock requirements.

Select the punch blank based on the holder-compatible shank diameter (D) and the required installed length (L) for your mold cavity/core design. This series covers D = 10–40 mm, enabling selection for a wide range of punch sizes within metric tooling.

• Match D to your holder: Ensure the chosen blank’s shank diameter falls within D 10–40 mm and corresponds to the punch holder bore/spec used in your tooling set.
• Match L to the forming stack-up: Available lengths are specified as L = 63–125 mm, 71–125 mm, and 80–125 mm. Pick the minimum length that provides the required engagement and safe clearance in the assembled mold.
• Tolerance/fit: While no tolerance values are provided, ball-lock interfaces generally require correct dimensional fit to maintain alignment and retention. Verify fit against your holder manufacturer’s tolerance range for the selected D.

Use the selected D to align with the punch holder and the selected L to satisfy travel, strike length, and interference constraints in the mold build.
