M2 Steel Ball Lock Pilot Punches - Round Tip, Light Duty, In

Ball lock pilot punches are used to establish repeatable part-to-die registration in light-duty inch stamping and progressive dies. The round tip helps the ball-lock locating mechanism center consistently, reducing positional drift over repeated press cycles—especially when tolerances stack across multiple stations.

• Progressive dies for connectors and small housings: Use these pilots to synchronize feed and forming steps, where short-range alignment stability is critical for reliable knockout and bending features.
• Die alignment fixtures and transfer jigs: The M2 steel body combined with the durable CRN coating supports frequent tool handling while maintaining reliable pilot engagement on each setup.
• Medical device components (non-precision-heavy forming): In applications where consistent feed registration is required but loads remain light, the round-tip geometry and secure ball-lock engagement improve cycle-to-cycle accuracy.

The M2/PS4 material options and the wear-focused CRN surface make this variant well suited for stable locating without overbuilding for lower load die tooling.

This series is offered in M2 steel (and also PS4 per the provided material options). M2 is a high-speed steel known for strong wear resistance under cyclic contact, making it suitable for repeated pilot engagement in light-duty press environments.

• M2 steel (high-speed steel): Typically supplied in a hardened and tempered condition for cutting-tool-like toughness/edge retention. In wear/contact applications, the trade-off is that very high hardness can reduce impact toughness, so proper tempering is important to balance durability.
• CRN coating: The CRN coating enhances surface hardness and reduces abrasive wear during repeated alignment cycles.
• PS4: An available alternative material option for balancing performance needs; select based on your tool life target and operating wear mode.

Because the specific heat-treatment state (e.g., target HRC or quench/temper schedule) and final hardness values are not provided in the input data, final hardness (HRC) should be confirmed with the supplier documentation for your chosen material option.

Selection starts with matching the pilot shank diameter D and the required point length to the die’s locating geometry. This series provides D (in) = 25 ~ 100 and a point length range depending on the configured length code.

• Choose shank diameter: Verify your guide-pin/bushing interface and select a D value within 25 to 100 (in) to ensure proper engagement and support.
• Match point length & length L: Available coded inch ranges include 200 ~ 500, 200 ~ 600, 200 ~ 700, and 225 ~ 700. Point-length variants also include B & L = 225 ~ 500, 225 ~ 600, 225 ~ 700 and C = 225 ~ 600 or 225 ~ 700, while one fixed configuration lists B & L = 250 ~ 700.
• P dimension (in): Select within 0.05 ~ 0.749, ensuring the ball/pilot stroke clears ejectors and nearby tooling.

Confirm allowable assembly clearance and fit: if your die tolerances are tight, validate that the selected P and point length provide full pilot seating without bottoming or interference on ball-lock engagement.
