Custom Carbide Die Bolt Punch Tool for Cold Heading
Custom carbide die bolt punch tooling for cold heading, recess forming, and segmented die assemblies. Jungu checks internal profile support, carbide risk, station fit, and tool-life target before quoting.
What is Custom Carbide Die Bolt Punch Tool for Cold Heading used for?
A custom carbide die bolt punch tool is used when a fastener needs an internal recess, special cavity, or die-supported forming feature under high cold-heading load. The key risk is not only whether carbide can resist wear, but whether the surrounding steel body supports it without edge breakage. If the drawing has a sharp internal corner, a thin wall around the carbide, or an unsupported impact zone, a simple carbide upgrade can crack earlier than a better-supported powder steel route. Jungu reviews the finished part drawing, punch or die-bolt interface, internal profile radius, material grade, machine station, coating expectation, and photos of cracking, poor fill, or galling before quoting. This product is for buyers who need a drawing-based tooling route, not a generic punch pin.
Common sourcing use
Cold heading, recess forming, internal profile forming, and segmented die assemblies where carbide support must match the forming load.

Technical Review Scope
What Jungu checks
- Internal profile drawing, fillet radius, recess depth, and tolerance zone
- Carbide support area, surrounding steel wall, press-fit risk, and impact direction
- Machine station, punch alignment, die body interface, and segmented die fit
- Fastener material, forming load, lubrication, coating route, and expected tool life
- Current failure mode: edge chipping, radial crack, galling, poor fill, or profile drift
Why no standard price is shown
This is B2B custom tooling. A reliable quotation depends on drawing, material, size, tolerance, machine setup, annual quantity, and the mould-life issue the buyer wants to solve. Jungu quotes after technical review instead of showing a misleading fixed price.
Information Needed for Quotation
| Profile data | Finished part drawing, internal recess profile, radius, depth, tolerance, and gauge method. |
|---|---|
| Tool interface | Punch/die-bolt drawing, station number, die body size, support length, and assembly photos. |
| Material route | Fastener material, hardness, coating expectation, carbide grade preference, and impact risk. |
| Failure evidence | Close-up photos of chipped carbide, cracks, galling, poor fill, or short-life wear pattern. |
Application and Buyer Fit
| Typical application | cold heading, recess forming, internal profile forming, and segmented die assemblies where carbide support must match the forming load |
|---|---|
| Buyer review focus | internal profile geometry, carbide support wall, fillet radius, die body fit, station alignment, coating route, and wear pattern |
| Quotation basis | drawing, material, tolerance, machine model, quantity, and target tool life |
| Review output | a supported carbide or alternative steel route matched to impact load, profile risk, and machine station |
Inquiry Process
- Send finished part drawing, tooling drawing if available, material grade, and current failure photos.
- Jungu checks whether the risk is wear, impact crack, profile fill, or support structure.
- Engineering selects carbide support, steel route, EDM finish, coating, and inspection points.
- Quotation follows the confirmed route instead of assuming that harder material is always safer.
FAQ
Is carbide always better for die bolt punch tooling?
No. Carbide helps concentrated wear, but poor support or impact loading can make it chip. Jungu checks support structure before recommending carbide.
What failure photo is most useful?
Send close-ups of the broken edge, side view of the crack path, the finished part defect, and the tool mounted in the station if possible.
Can Jungu change the support design?
Yes. If the original route breaks repeatedly, we can review support length, radius, press fit, coating, and steel-carbine transition before quoting.
Can this product be customized?
Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
Need this tooling reviewed?
Send drawings, machine model, material, and current failure photos for review.
