Product Guide
Application Scenarios+
Ball lock pilot punches are used in progressive and transfer die sets to maintain repeatable die alignment during high-cycle production. The round tip variant supports stable pilot engagement, which helps prevent gradual mislocation when parts stack up over many strokes.
- Automotive connector and terminal tooling: The heavy-duty hardened M2 steel body provides long wear for continuous die positioning, while the XCDP coating helps reduce surface wear at the pilot contact zone.
- Consumer/industrial housing brackets in metric production: Use these punches to improve feed reliability and keep cavity/core registration consistent across multiple forming stages.
- Electronics enclosure and small-part progressive lines: The availability of multiple shank diameters and point lengths (D and L1 ranges) enables matching the pilot engagement depth to the corresponding ball-lock receiver features.
This product is suited to tooling where accurate positioning and durable pilot contact under repetitive load are critical.
Material & Process Details+
This variant is available in M2 and PS4 steel. M2 is a high-speed steel (commonly associated with AISI M2) known for strong wear resistance under sliding/impact conditions typical at pilot interfaces. PS4 is offered as an alternative material option for specific shop preferences and performance targets.
These punches are described as hardened for long wear. In practice, hardened steel improves resistance to galling and point/edge wear at the round tip during repeated die cycles, but can reduce toughness compared with lower-hardness steels—so matching the design to the press load profile is important.
- Hardness (HRC): Specific HRC values are not provided in the available data.
- Coating role (XCDP): The XCDP coating supports reduced wear at the pilot contact area.
Sizing & Selection Guide+
Select the pilot punch dimensions by matching the shank and point geometry to the corresponding die set ball-lock pilot system. Start with the required D (shank dia.) within 10 ~ 40 mm, then choose a L1 (point length) from the available ranges: 12–21, 15–27, or 21–32 mm.
Next, verify the overall L (length) against your tool stack-up. Available L ranges are 65–112, 65–127, 73–127, 92–127, or 112–127 mm, depending on the configuration.
- P dimension: Choose P = 1.45 ~ 29.95 mm to align the ball-lock/engagement geometry.
- Tolerance/fit: Use the mold’s specified clearance for the pilot receiver. For ball-lock engagement, avoid oversized shanks and insufficient point length that could lead to shallow contact and positional drift.
- Fixed vs configurable: Material (M2 or PS4) and the geometric sets (D, L1, L) are configurable within the stated ranges.
Frequently Asked Questions
Which material option (M2 or PS4) should I choose for long-run progressive die alignment?+
The listing provides two material options: M2 and PS4. The product description specifically emphasizes hardened M2 steel for long wear and includes an XCDP coating to reduce wear at the pilot contact. If your primary concern is wear at the round tip during repeated alignment, M2 is the most directly supported choice by the provided description.
What shank diameter D and point length L1 ranges are available for this ball-lock pilot punch?+
The available D (shank dia.) range is 10 ~ 40 mm. For L1 (point length), the available ranges are 12–21, 15–27, or 21–32 mm. Match D to the pilot hole/bushing size and select L1 based on the required engagement depth in the die set.
How do I choose the overall length L for my press tool stack-up?+
This product lists multiple L (length) ranges: 65–112, 65–127, 73–127, 92–127, and 112–127 mm. Use the die set’s total stack-up (including plates and wear components) to ensure the pilot point reaches the engagement feature without bottoming. Verify that the selected L leaves appropriate clearance for assembly and replacement.
What is the significance of the P dimension (1.45–29.95 mm) for ball-lock engagement geometry?+
The P dimension is specified as 1.45 ~ 29.95 mm. In ball-lock pilot systems, this dimension is part of the engagement geometry, so it should be matched to the corresponding receiver feature in your die set. Use your die drawings/standards to map P to the intended contact and locking position.
Does the XCDP coating change how I should specify point engagement to avoid early wear?+
The product description indicates an XCDP coating intended to reduce wear at the pilot contact. Even with coating, correct point engagement is still governed by your selected L1 and the receiver geometry. Choose L1 so the round tip provides stable contact without excessive penetration that could accelerate wear on mating components.
