Why Label Material Matters
Every asset in ToolWatch is only as trackable as the Label or label attached to it. A barcode label and/or QR code is worthless the moment it peels off, fades past readability, or comes loose in the field — and re-labeling a tool after the fact costs far more labor than labeling it correctly the first time. The right material depends on the environment the tool works in, how long the tool stays in service, and how the tool is used day to day (handled constantly, exposed to heat/moisture, washed down, etc.).
This guide ranks the four most common labeling approaches and explains when each one is the right call.
At a Glance: Top Recommendations
Rank | Method | Best For | Key Trade-off |
1 | Laser Engraving | High-value, long-life, or harsh-environment assets | Upfront equipment cost + per-tool labor time |
2 | Metal Labels, Riveted | Equipment with a drillable edge; rugged field use | Requires drilling; not for thin/finished surfaces |
3 | Metal Labels, Epoxied | Tools that can't be drilled but need a rugged Label | Cure time; surface prep is critical to bond strength |
4 | Standard TW Labels (Adhesive) | The majority of everyday tools and consumables | Adhesive-dependent; needs the right label spec for the environment |
Rule of thumb: start with standard adhesive Labels. Reserve laser engraving, riveting, or epoxied Labels for the assets where a lost Label would actually hurt — high value, long service life, or extreme conditions.
The Four Methods, Ranked
1. Laser Engraving — Best Overall Option
Laser engraving marks the identifier (barcode, QR code, serial number, or asset ID) directly into the surface of the tool itself, rather than attaching a separate label. There's no adhesive and nothing to fall off.
Why it's #1:
Permanent: the mark can't peel, fade, or be knocked loose — it's part of the tool.
Environment-proof: unaffected by heat, humidity, oil, solvents, or washdown — the exact conditions that cause adhesive labels to fail.
Lowest lifetime cost per asset: one engraving pass outlasts multiple rounds of label replacement, which matters most for tools that stay in service for years.
Works across materials: effective on steel, aluminum, wood, bamboo, and most plastics.
Trade-off:
Requires an upfront equipment investment (fiber laser engravers used in the field run in the range of $1,500–$2,000) and per-tool setup/handling time, so it's most cost-effective when done in batches.
Less practical for very high-SKU, low-unit-value consumables where the labor time isn't worth it.
Best for: uniquely tracked, high-value, or long-life tools and equipment — especially anything that will spend time outdoors, in high heat, or in wash-down areas.
2. Metal Labels, Riveted
A pre-printed or pre-serialized metal Label is mechanically fastened to the tool with a rivet through a drilled hole.
Why it works:
Mechanical attachment, not adhesive: the Label can't be peeled or dissolved off by heat, moisture, oil, or cleaning chemicals — it has to be physically removed.
Rugged: holds up to washdown, abrasion, and rough handling better than any adhesive-based option.
No in-field printer needed: Labels can be pre-printed/serialized off-site and simply riveted on during intake, which is fast once the hole is set.
Trade-off:
Requires drilling a hole, so it isn't an option for thin, delicate, or cosmetically finished surfaces.
A determined effort can still pry a riveted Label loose, so it's strong but not tamper-proof.
Best for: rugged field equipment with a solid edge or flat surface to drill — lifting equipment, rigging hardware, and heavy tools that see constant outdoor or washdown use.
3. Metal Labels, Epoxied
Same durable metal Label as above, but bonded to the tool with an industrial epoxy adhesive instead of a rivet.
Why it works:
No drilling required: a good option for tools where you can't (or shouldn't) put a hole — thin housings, sealed components, finished surfaces.
Very strong bond once cured: properly applied epoxy substantially outperforms pressure-sensitive adhesive labels in heat and moisture resistance.
Durable Label material: the metal Label itself still resists wear and abrasion far better than a plastic or vinyl label would.
Trade-off:
Needs cure time before the tool goes back into service — plan labeling in batches, not one-off in the middle of a shift.
Surface prep (clean, dry, degreased) is critical; a rushed application undermines the bond and defeats the purpose.
Harder to remove or relocate than a riveted Label if the tool is reassigned or the Label needs replacing.
Best for: assets that need a rugged, semi-permanent Label but can't be drilled — a good middle ground between riveting and standard adhesive labels.
4. Standard ToolWatch Labels (Adhesive) — Follow the Labeling Best-Practice Guide
Peel-and-stick barcode or QR labels remain the right default for most of a fleet. They're the fastest and lowest-cost way to Label high volumes of tools and consumables, and they're what the ToolWatch mobile app is optimized to scan out of the box.

Why it's still the default:
Fastest to apply: no drilling, no cure time — ideal when you're labeling hundreds or thousands of items during onboarding.
Lowest per-unit cost: the right choice for consumables and lower-value tools where engraving or metal Labels don't pencil out.
Good enough for most environments: indoor, climate-controlled, or short-to-medium asset life situations rarely need a hardened Label.
Getting it right matters:
Match the label to the environment: use an industrial-grade, laminated label rated for the heat/humidity/UV exposure the tool will actually see — not a standard office label.
Avoid makeshift fixes: adhesive workarounds like gorilla tape may hold a label on temporarily, but they degrade quickly in heat and humidity and often obscure the scan window, causing more mis-scans than they prevent.
Follow the Unique vs. Quantity labeling guidance: refer to ToolWatch's Unique vs. Quantity Tool Best Practices guide to determine whether an asset should be serialized individually or tracked at the model/quantity level before you print labels — this determines the label format you need.
Best for: the majority of everyday tools, consumables, and any asset in a stable indoor environment.
How to Choose: Quick Decision Framework
If the asset is… | Recommended approach |
High value, long service life (years), or hard to replace | Laser engraving |
Exposed to washdown, heavy outdoor use, or rough handling, with a drillable surface | Metal Label, riveted |
Needs a rugged Label but can't be drilled (thin, sealed, or finished surface) | Metal Label, epoxied |
A high-volume consumable or standard tool in a normal indoor environment | Standard adhesive TW Label (per labeling best-practice guide) |
Currently held together with tape, glue, or another makeshift fix | Re-labeling using one of the three hardened options above — treat the makeshift fix as a signal the environment calls for more than a standard label |
