Numbering Head Model Comparison

Selecting the Right Quick-Change Numbering Head: Model 80P vs. 85P vs. 83P Comparison

When your industrial marking requires frequent character changes—such as date codes, batch numbers, custom IDs, or non-sequential serialization—but not fully automatic consecutive indexing, Numberall’s Quick-Change Numbering Heads deliver the fastest manual adjustments with deep, permanent indents.

These heads integrate seamlessly into any power press or use the included vinyl-coated hand shank for manual striking. All models are precision-machined from heat-treated tool steel in Maine, USA, and backed by our lifetime support—ensuring decades of service in oily, dusty, or high-heat shops where electronic alternatives falter.

Model 80P: 1-Wheel Quick-Change (Most Economical)

• Operation: Rotate the external knurled knob to adjust the ones (units) wheel in either direction—no tools required.
• Other Wheels: Manually adjusted with a spanner wrench.
• Sight Reading: Features direct-sight indexing on the knob-controlled wheel for instant verification.
• Best For: Low-volume or repetitive serial numbering where only the last digit changes frequently.
• Primary Advantage: The most cost-effective solution for basic batch or sequential coding.

Model 85P: 2-Wheel Quick-Change (Balanced Efficiency)

• Operation: Slide the wheel shaft right to engage the ones wheel; slide it left to engage the tens wheel. Adjust both with the knurled knob.
• Other Wheels: Manually adjusted with a spanner wrench.
• Sight Reading: Direct-sight indexing on both quick-change wheels.
• Best For: Mid-volume applications where the first two digits shift often (e.g., date + batch combinations).
• Primary Advantage: Faster setup than the 80P for two-digit shifts with minimal added complexity.

Model 83P: Universal Quick-Change (Maximum Versatility)

• Operation: Turn the selector button(s) to target any wheel, slide the shaft to engage, and rotate the knob. No spanner wrench needed for any wheel.
• Configurations: Available with a single selector (≤6 wheels) or double selector (up to 12 wheels).
• Sight Reading: Direct-sight indexing on all wheels for 100% pre-strike accuracy.
• Best For: Complex or highly variable coding (e.g., mixed alpha-numeric codes or custom IDs) where every digit may change per part.
• Primary Advantage: Ultimate flexibility and speed; the only choice for dynamic production environments.
