Ball Lock Regular Punches - Light Duty, Inch

These light-duty ball-lock punches are used inside precision die sets and injection-mold tooling to provide secure part retention and repeatable ejection during cycling. The ball-lock style contact helps keep the punch positioned under load, which is critical when downstream operations require consistent transfer or clearing.

• Progressive die stations for small components: The inch-coded geometry and X-shaped tip promote stable contact during short, frequent strokes, improving ejection uniformity in light-workload builds.
• Connector and small housing mold inserts: The X-tip supports smooth action and controlled movement at the contact area, helping reduce the risk of misalignment-driven wear in fine cavity layouts.
• General press tooling for precision die parts: Available in M2 or PS4 steel for wear-focused blank performance, the punch is suited when surface durability matters more than maximum toughness.

Select the X-tip variant when you need consistent punch performance and stable positioning in light-duty workflows.

This product is available in M2 or PS4 steel, both chosen for wear-focused blank performance in punch applications. While exact hardness values are not provided in the available specifications, M2 is commonly selected for strong wear resistance in cutting and punch environments, offering a balance of hardness and toughness. PS4 is also used as a tool steel option where surface wear performance is prioritized.

• M2 option: Typically selected for improved wear resistance; benefits often come with a trade-off against extreme toughness under shock loading.
• PS4 option: Chosen for applications where durable contact surfaces and stable punch behavior are required for light-duty cycles.
• X-tip geometry: Places demand on tip wear characteristics and maintaining consistent engagement during repetitive motion.

For best results, coordinate the chosen steel with your shop’s standard heat treatment route (e.g., quench-and-temper) to reach the target hardness and dimensional stability for punch tooling.

Dimension selection should start with the shank diameter (D) and the overall length code (L) required by your die layout. This series offers shank diameters D = 25 ~ 100 in and point/length options where L (coded inch) ranges from 200 ~ 500 up to 200 ~ 700, depending on the coded configuration.

• Match D to the mating guide/bore: Choose the D (25–100) that aligns with your punch retention and alignment features to avoid excessive clearance or binding.
• Select the correct point and length structure: Use the coded point-length variants: Point Length B & L offers ranges 225 ~ 500, 225 ~ 600, 225 ~ 700; Point Length C & L offers 225 ~ 600, 225 ~ 700; Point Length D & L offers 250 ~ 700 (with additional 250 ~ 700 variants indicated).
• Verify dimensional limits for engagement: Control small geometry features including P = 0.04 ~ 0.75 in and W = 0.04 ~ 0.437 in so the X-tip contact engages correctly without over-driving.

Tolerances are not specified here; therefore, confirm your die build tolerances and punch-to-bore fit requirements with the mating components before finalizing the coded length and shank diameter.
