Gauge-row concentration
Localized gauge wear can point to abrasive wall contact or hole-control conditions. Compare it with face-button wear before deciding what to change.
ROCK DRILLING / FAILURE-LED SELECTION
Identify the Failure.
Define the Next Carbide Trial.
Button wear, fracture location, retention and hole behavior help determine whether the next trial should change grade, profile, fit or drilling parameters.

Add operating context
Rock hardness alone is not enough. Abrasivity, fracture pattern, water, impact energy and bit design also matter.
ENGINEERING LOGIC
Why this direction
The selected path narrows the next review; it does not replace engineering confirmation.VISIBLE SYMPTOMFlattened gauge-row wear
MECHANISM TO VERIFYAbrasive wear / thermal contribution
DATA NEEDEDGauge vs face wear, formation, flushing, rotation and impact
POSSIBLE TRIAL CHANGEProfile / grade direction plus parameter check
DTH impact balance
DTH drilling combines impact and abrasion. A more abrasion-biased candidate may increase chipping risk if impact toughness, button support or operating parameters are not suitable.
Separate heat from wear
Thermal checking, inadequate flushing and matrix washout should be separated from simple carbide wear before a grade change is proposed.
PRE-TRIAL CHECKS
Do not change material until these checks
Use the worksheet to send evidence that separates carbide selection from fit, body and operating causes.| Check | What to inspect | Why it matters | What to send |
|---|---|---|---|
| Fit & retention | Mating dimensions, interference and button-seat condition | Separates material failure from fit or retention failure | Drawing + close-up |
| Bit body | Washout and support around the insert base | Weak support can accelerate damage around the button | Side-view photo |
| Flushing | Cuttings removal, blocked passages and cooling | Regrinding and heat can change the observed wear pattern | Pressure + passage data |
| Operating parameters | Impact pressure, rotation and feed | Parameter imbalance can concentrate wear or fracture | Rig settings |
| Wear distribution | Gauge-row versus face-button wear | Distinguishes localized wear from a more general pattern | Two comparison photos |
| Formation | UCS, mineralogy, abrasivity, fractures and water | Rock hardness alone is not enough for selection | Available formation data |
ROCK-DRILLING FIELD ARCHIVE
From drilling equipment to bit inspection and severe wear
These authorized photographs document rock-drilling equipment, new and inspected bit assemblies, a severely damaged tricone bit and a carbide-button product. They provide application and failure-analysis context; they are not presented as a traceable customer performance case or proof of drilling-life improvement.
Surface rock-drilling equipment
Equipment context for discussing drilling system, formation, flushing and operating parameters. The photographs do not identify a measured project result.
New tricone roller bit
Unused bit reference for reviewing cone layout, insert distribution, gauge protection and threaded connection.
Field bit inspection
Inspection context showing why full-bit, cone, seat and adjacent-insert observations should accompany close-up wear photographs.
Severely damaged tricone bit
Severe damage and insert loss require checks of cone, bearing, seat, support and operating load before any carbide-grade change.
Carbide button bit product
Product reference for button profile and layout discussion. Fit, interference and inspection remain specific to the approved bit design.
GRADE SPECIFICATION REFERENCE
SS20CB published performance reference
Use this accessible table as a material-reference starting point when preparing a rock-drilling inquiry. It summarizes a Ruixin grade specification dated 28 March 2020; it is not a current batch certificate or a field-life commitment.| Property | 2020 specification reference |

2020 grade specification reference only. Current-order composition, properties, inspection methods and acceptance limits must be reconfirmed before production. These values are not a current batch certificate, drilling-efficiency claim or service-life promise.

CONTROLLED VALIDATION
From diagnosis to a controlled field trial
Share wear photos + operating context
Gauge-row and face-button views make the starting pattern easier to compare.
Review likely mechanism, grade, profile and fit
Engineering checks the carbide together with the bit body, fit and operating data.
Agree sample quantity + inspection checklist
Confirm the relevant product-family trial quantity and inspection scope before sampling.
Record metres / hours and field feedback
Compare the trial against the baseline in a controlled formation before batch release.
