What Happens During Professional Drill Bit Refurbishment?
The Bit Brief · Refurbishment & Repair
“Refurbishment” can mean different things at different shops. For carbide button rock-drilling bits, it generally involves deciding whether a worn tool can return to work and which approved restoration steps would make sense. The best process starts with inspection—not a grinder.
1. Intake and identification
A useful service request identifies the bit maker, model or shank where known, diameter, quantity, visible defects and project deadline. For large-diameter or specialty bits, a photograph showing scale and identification markings is especially valuable. This helps prevent misunderstandings about equipment compatibility.
2. Condition and serviceability assessment
The provider checks the extent of carbide wear, button damage, gauge condition and relevant steel-body issues. Inspections may include additional checks appropriate to the tool and proposed work. Not every provider offers every type of testing or repair, so ask what is actually included.
This is the point at which the recommendation may be sharpen, repair, replace individual eligible buttons, or retire. A trustworthy assessment does not treat every tool as recoverable.
3. Quote and approval
Before authorizing work, understand the proposed scope, price, what happens if additional damage is found, expected turnaround and return logistics. Request clarification about whether freight is included. For nationwide mail-in work, plan the transit window as part of the service decision.
4. Approved restoration work
Depending on the accepted scope, qualified refurbishment may include button profile restoration or replacement of eligible damaged carbide inserts. The working geometry and finished dimensions should be evaluated against relevant manufacturer guidance. Do not assume body welding, hardfacing, coatings or every advanced repair method is offered unless the shop confirms it.
5. Finished-tool inspection
The goal is a safe and serviceable tool, not a shiny photograph. The condition of gauge buttons, face profile, flushing passages and body matters. Ask how a completed bit is checked and what limitations, if any, should be noted before return to the rig.
6. Document the next service interval
When the tool returns, note its service date and track the drilled footage and wear pattern during use. That record tells you whether refurbishment provided economic value and when to inspect again. It also informs the next buying decision.
For 15-, 18- and 20-inch bits
Large-diameter bits may have substantial replacement costs and complex freight arrangements. Share manufacturer information and physical dimensions before shipping. A size mentioned in an article does not confirm that DG Carbide can service that exact bit; compatibility must be confirmed by the team.

Frequently asked questions
Does refurbishment always include button replacement?
No. The scope depends on the condition of the tool. Some bits need only sharpening; others need repairs, and some should be retired.
Can a quote change after the bit arrives?
A preliminary quote may be revised if physical inspection reveals additional defects. Ask the provider how approval is handled before further work.
