Carbide Button Bit Sharpening
Worn buttons can cost drilling crews time and money.
Have flattened or unevenly worn carbide buttons? Send DG Carbide your bit details for a practical sharpening assessment before purchasing replacement tooling.
For drilling contractors and maintenance managers
Get the bit profile checked before the next drilling job.
Quarry crews, rock-drilling contractors and equipment managers depend on serviceable tooling. As tungsten-carbide buttons wear, their shape changes. Regrinding may be appropriate for eligible bits, but the correct decision depends on the bit design, remaining carbide and overall condition.
Wear patterns
Look for flattened button tops, uneven gauge wear and other changes at the cutting face.
Tool compatibility
Provide the manufacturer, model, diameter and any identifying markings on your DTH or rock-drilling bit.
Sharpen or replace?
Sharpening is not a substitute for replacing missing inserts or addressing bit-body damage.
Tooling assessment
What the maintenance team should look for.
Button profile & gauge wear
Photograph uneven or flat carbide tops, especially on the outer gauge area of a DTH bit.
Damage beyond normal wear
Point out broken or missing inserts, cracks and shank issues so the right service can be considered.
How service works
A quick assessment starts with the right photos.
Send a straight-on image of the bit face, a close view of the gauge area and a clear view of the shank. Physical inspection may still be needed before work is approved.

A clearer path for your team
When sharpening makes sense
Carbide button sharpening may be an option when the remaining inserts and bit body are in serviceable condition. Our review focuses on suitability—not a guaranteed restoration of every worn bit. Missing buttons may require a separate replacement assessment.
Flattened buttons
A candidate for a sharpening review, subject to insert condition.
Missing or broken buttons
Request a carbide button replacement assessment.
Body or shank damage
Ask whether broader bit refurbishment is appropriate.
Service FAQs
Questions drilling contractors and maintenance managers ask.
Do you sharpen DTH carbide button drill bits?
Send the make, model, size and clear photos. We will review whether the specific bit is eligible before accepting service.
Can sharpening repair missing carbide buttons?
No. Missing or damaged buttons are evaluated separately for replacement, and damage to the surrounding bit may affect repair suitability.
What determines sharpening cost?
Diameter, make, model, condition, quantity and work required. Ask for a quote and confirm transportation costs separately.
Can I ship carbide drill bits for sharpening?
Yes. Contact us before shipping for tooling acceptance, receiving address and return-shipping arrangements.
