Ball-Lock Regular Punches
Solid-shank ball-lock punches for general-purpose piercing and blanking. No internal ejector mechanism — the slug falls through the die clearance by gravity. Preferred for moderate-thickness materials where slug pulling is not a concern. Available in Heavy Duty and Light Duty, inch and metric, with 14 coating options.
Coating Selection for Regular Punches
Regular punches benefit from the same coating options as ejector punches. The top 4 coatings for regular punch applications:
| Coating | Hardness (HV) | Friction Coefficient | Best For |
|---|---|---|---|
| CRN | 1,750 | 0.3 | General purpose — mild steel, copper alloys |
| TiN (XN DayTride®) | 2,300 | 0.4 | Carbon steel, moderate abrasion |
| TiCN (XCD) | 3,000 | 0.2 | Stainless steel, AHSS, abrasive materials |
| DLC (XVP) | 4,000+ | 0.1 | Aluminum, copper — anti-galling |
Ideal Applications for Regular Punches
General Sheet Metal Piercing
Standard piercing of round, square, and oblong holes in mild steel 0.5-3mm thick. Slug drops through die clearance without assistance.
Why regular punches fit: No ejector mechanism needed — gravity and die clearance handle slug removal. Lower cost than ejector punches with simpler internal geometry for maximum rigidity.
Tight-Pitch Multi-Station Dies
Progressive dies with closely-spaced punch stations where the solid shank provides maximum rigidity under lateral strip forces.
Why regular punches fit: The solid shank cross-section is 15-20% stronger than an equivalent ejector punch (which has a hollow bore for the ejector pin). Critical for maintaining punch-to-die alignment in tight-pitch layouts.
Engineering Resources
Application Scenarios
Regular ball-lock punches are the optimal choice for these applications:
Medium-to-Thick Gauge Carbon Steel
Piercing material above 2mm thickness where slug weight ensures reliable gravity dropout.
Heavy slugs fall through the die clearance by gravity alone. Ejector mechanism is unnecessary, saving 20-40% on punch cost.
Large-Hole Blanking Operations
Creating holes above 10mm diameter where slug-to-punch contact area is large and dropout is reliable.
Large slugs have sufficient weight for reliable gravity dropout. Regular punches provide maximum shank rigidity for heavy blanking loads.
Cost-Optimized Standard Production
Standard production runs where slug pulling history is clean and maximizing tooling budget is the priority.
Regular punches cost 20-40% less than ejector equivalents. When slug management is not a concern, they deliver identical performance at lower cost.
