Key Benefits
- Hardness held between HRC 50 and HRC 64 to resist edge wear during repetitive sheet metal punching operations
- Choice of high-wear tool steels including DC53, SKD-11, M2, and tungsten steel matched to your target sheet material
- Production capacity of 1000 pieces per month accommodates regular consumable tool restocking schedules
- Custom coatings applied to punch working faces to reduce galling and lower cutting friction
- Made to drawing to fit specific CNC turret or single-station punch press tooling holders
- Surface treatments and protective packaging prevent edge chipping and corrosion during transit
Problems It Solves
- Rapid edge wear and chipping when punching abrasive or hard sheet stock with standard tool grades
- Sheet material galling and sticking to punch flanks caused by lack of application-specific surface coatings
- Difficulty sourcing replacement punch tooling for non-standard or legacy CNC punch press holder profiles
- Inconsistent punch service life caused by uncontrolled core and surface hardness variation
Who It Is For
- Tooling procurement engineers sourcing custom punch and die inserts for CNC sheet metal punching presses
- Fabrication shop maintenance managers seeking reliable replacement punch tooling ground to print
- Metal stamping and perforated sheet manufacturers needing monthly batches of wear-resistant punch dies
- OEM machinery builders integrating custom punch dies into specialized sheet processing machines
Application Scenarios
- Sheet metal fabrication shops running high-volume punching cycles that require extended die wear life
- Machine construction applications requiring custom-profile punch and die sets for proprietary stamping patterns
- Replacement of worn punch dies in CNC turret punch presses where original tooling is obsolete
- Heavy-gauge sheet piercing operations requiring tough alloy tool steels such as DC53 or 42CrMo
- High-speed punching lines using specialty coatings to avoid material pickup on punch working faces
Technical Features
- Controlled heat treatment delivering final hardness between HRC 50 and HRC 64
- Selection of high-speed, cold-work, and tungsten carbide tool materials including SKH51, D2, and DC53
- Custom protective surface coatings matched to the punched metal grade
- Monthly production capacity of 1000 pieces for puncher and bender tooling
- Packaged in PP bags, cartons, crates, or boxes to protect precision cutting edges
Materials
- D2, SKD-11, and Cr12MoV cold-work tool steels for balanced wear resistance and edge holding
- DC53 for improved toughness and chipping resistance over standard D2 tooling
- SKH51, M2, and W18Cr4V high-speed steels for high-cycle punching applications
- Hard alloy tungsten steel for extreme abrasion resistance in high-volume production
- 42CrMo, 65Mn, 9CrSi, and 6CrW2Si for specialized tool bodies and shock-loaded components
How It Is Made
- 1
Tool drawing analysis to evaluate punching geometry, clearance specifications, and tool steel grade
- 2
Rough machining and profile turning of the punch die blank
- 3
Precision heat treatment and tempering to achieve the target hardness within HRC 50 to 64
- 4
Finish grinding of punch working surfaces and mounting shanks
- 5
Application of customized anti-wear coating if specified on the drawing
- 6
Dimensional check, protective oiling, and packaging in protective crates or cartons
Quality Control
- Hardness testing across punch working faces to verify compliance with HRC 50 to 64 specification
- Dimensional inspection of critical die diameters, clearance angles, and mounting locations
- Visual check of sharpened cutting edges for burrs, cracks, or grinding marks
- Edge protection and corrosion-preventive oiling applied prior to sealing in cartons or crates
Customization Options
- Manufactured directly to customer tooling prints, CAD models, or physical tool samples
- Material selection tailored to the sheet gauge and material being punched
- Hardness targeted to your specific requirement between HRC 50 and HRC 64
- Custom surface coatings applied to enhance wear life and reduce material adhesion
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Standard catalogue punch tooling | Catalogue punches ship from stock but cannot accommodate non-standard hole profiles, modified clearances, or custom shanks |
| Standard D2 punch dies | DC53 or tungsten steel dies provide higher chipping resistance and longer runs, but material cost is significantly higher |
| Uncoated punch dies | Custom-coated dies resist adhesive wear and galling on stainless sheet, though they add processing time to production |
Use Guide
- Submit your punch drawing specifying mounting style, die clearance, and material grade
- Indicate the thickness and type of sheet metal being punched to select appropriate hardness
- Specify your required hardness within the HRC 50 to 64 range on the drawing
- Inspect alignment of the punch and mating die in the press turret before running full-speed cycles
- Maintain appropriate lubrication on cutting faces during sheet punching operations
