R28 configuration and quotation guide
R28 Threaded Button Bit. A threaded button bit is the cutting component of a top-hammer drill string. Thread family, diameter, face, body/skirt, button layout and flushing are separate configuration choices.
- R28: The enquiry can distinguish multiple bits within a single thread family.
- Providing the site context makes alternative bit configurations easier to assess.
- Configuration, included items and acceptance basis stated in the written quotation
Request a Configuration-Based Quote
Send exact bit thread system and mating rod drawing; bit diameter and hole requirement; face, buttons and flushing arrangement; rock condition, drill model and operating context; quantity and delivery country. Not sure is accepted where identification is needed.

Technical Specifications
| Model / family identity | R28 |
|---|---|
| Product type | Threaded Button Bit |
| Requested thread family | R28 as stated in the catalog identity; not a cutting diameter or compatibility guarantee. |
| Drilling system | Top hammer; the bit connection must match the bit-side rod or adapter. |
| Thread identity | Use the exact family stated in the title and verify its controlled mating geometry. |
| Cutting diameter | Select for the hole requirement; the thread-family number is not the cutting diameter. |
| Face and body | Specify face profile and regular/retrac/guide or other approved body/skirt form. |
| Buttons and flushing | Specify center/gauge layout, button profile and flushing configuration together. |
| Order configuration | The accepted quotation identifies the exact configuration, part/drawing revision, quantity and supplied items. This page is a configuration enquiry. |
Final interface dimensions, selected configuration and supply scope are stated in the formal quotation or approved drawing.
Compatibility and Required Interfaces
Complete top-hammer string
R28 configuration review
Identify the rock drill, shank adapter, rod and coupling arrangement.
Confirm the final bit configuration against the selected string and hole duty.
Threaded Bit Face and Connection
Connection and cutting specification separated
The thread establishes fit while diameter and working-face geometry establish the requested bit configuration.
Buyer value
The enquiry can distinguish multiple bits within a single thread family.
Selection condition
Every size and face option must be explicitly offered before ordering.
Ground-informed configuration
Rock hardness, abrasiveness and fracturing are considered with the face, buttons and flushing.
Buyer value
Providing the site context makes alternative bit configurations easier to assess.
Selection condition
No penetration-rate or service-life claim is made without a defined test.
Configuration-specific quotation
The R28 enquiry is identified by its catalog model/family and the requested connection, application and supply scope.
Buyer value
The written offer can return a reviewable part/configuration identity and itemized supply list.
Selection condition
A model or page reference is not itself a complete order code; approve the offered configuration before ordering.
Application Scenarios
- Threaded-bit replacement on an identified top-hammer string
- Rock-specific bit-configuration enquiries with stated hole requirements
- Regular, retrac or other body-profile review where the selected system supports it
Confirm Before Ordering

Quality and Pre-Shipment Checks
01
R28 identity and configuration check
Acceptance requirement: compare the offered item with the approved model/part/drawing revision.
This is an order-inspection requirement, not a completed inspection result or certification statement.
Agree checks covering exact bit-side thread family; mating rod/adapter drawing; bit diameter; face profile before order release.
02
Interface and functional evidence
Acceptance requirement: agree the relevant dimensional and, where applicable, functional verification for the quoted configuration.
No test outcome or universal performance figure is claimed. The test arrangement and pass criteria must be tied to the actual offered item.
Use the agreed threaded button bit drawing/data sheet and record the relevant connection, fit or operating conditions.
03
Supply, quantity and packing reconciliation
Acceptance requirement: match each delivered line item to the approved supply scope and packing list.
The required marks, protection and document scope must be written in the order.
Check item identification, quantity, visible condition and the agreed packaging/documentation.

Order Documentation
Commercial invoice and itemized packing list: agree required content with the order.
Origin, inspection, test or transport documents: state destination/project requirements before quotation; availability must be confirmed for the offered configuration.
Frequently Asked Questions
What does this R28 page identify?
A threaded button bit is the cutting component of a top-hammer drill string. Thread family, diameter, face, body/skirt, button layout and flushing are separate configuration choices.
Is a thread family a complete bit specification?
No. State the diameter, face, body/skirt, button layout and flushing, and identify the mating rod or adapter.
Can the same nominal number identify different connections?
Yes. Preserve the exact thread designation and verify the mating part or drawing; do not substitute one system by appearance.
Which configuration details are needed for quotation?
Provide exact bit-side thread family; mating rod/adapter drawing; bit diameter; face profile; regular/retrac/guide body; button profile and center/gauge layout. Also include flushing configuration; rock hardness/abrasiveness/fracturing; hole depth and straightness; quantity by approved configuration, quantity and destination. The offer should state the exact configuration for approval.
What is included in the supply?
The quotation itemizes the supply. Typical enquiry lines are: threaded button bit in the quoted cutting and connection configuration; rods, couplings and adapters only as separately listed. No unlisted accessory or mating component is assumed included.
How are quantity, delivery and inspection requirements agreed?
Send the required quantity, destination and any packing or inspection requirement with the R28 enquiry. MOQ, dispatch timing, warranty and document scope are stated in the written quotation for the agreed configuration.
