ROCK-DRILLING & MINING HARDMETAL
Cemented Carbide Rock-Drilling and Mining Tool Components
Technical sourcing of carbide buttons, inserts, wear elements and steel-supported tool components for drilling, mining, quarrying and construction duty.
MNK-G.S.A reviews the drilling system, rock conditions, tool geometry, carbide grade, steel body, retention route and inspection plan as one sourcing package. A button shape or nominal diameter alone is not sufficient to establish interchangeability.
Drilling and Wear Routes
Top-Hammer
Buttons and inserts for threaded or tapered percussion bits, selected with the bit body, connection, face design, flushing arrangement and rock condition.
Down-the-Hole
Face and gauge buttons for DTH bit configurations, with the hammer system, hole size, air and cuttings evacuation, formation and service strategy defined.
Rotary & Construction
Carbide elements for selected rotary, excavation, trenching and construction-tool duties, supplied against an approved drawing or equipment reference.
Application labels describe the operating route; they do not define a universal carbide grade. The requested life, failure mode and regrinding or replacement strategy must be stated.
What the Supply Package Can Include
Loose Hardmetal Components
- Spherical, ballistic, conical or drawing-defined buttons
- Face, gauge and wear-protection inserts
- Chisel, wedge or special-profile carbide elements
- As-sintered, ground or finish-machined condition
- Prototype, trial batch and repeat-production routes
Supported and Finished Tools
- Carbide fitted to approved steel bit bodies or supports
- Complete or semi-finished drawing-based components
- Specified interference, joining or mechanical-retention route
- Heat treatment, finishing, marking and packing requirements
- Dimensional and batch documentation as agreed
Specify the Duty Before the Grade
Operation and Formation
- Top-hammer, DTH, rotary or other defined system
- Rock type, abrasivity, fracturing and variability
- Hole diameter, depth, orientation and flushing medium
- Impact, rotation, feed and equipment reference
- Observed wear, fracture, pull-out or body failure
Component and Material
- Profile, diameter, height, radii and tolerances
- Face or gauge position and required projection
- Carbide family, binder, grain-size and property limits
- Pocket geometry, interference or retention requirement
- Steel body, heat treatment and finished-tool drawing
A harder grade is not automatically a better drilling grade. Wear resistance, toughness, button geometry, retention and the surrounding steel must be balanced for the actual duty. Proposed alternatives require technical approval against the governing equipment or customer specification.
Standards and Their Boundaries
| Reference | Verified public scope | Procurement boundary |
|---|---|---|
| ISO 513:2012 | Application classification for cutting by chip removal, not a chemical grade equivalence. Mining, percussion drilling, wire drawing and metal forming are outside its scope. | P, M, K, N, S and H groups must not be used as mining-grade equivalents. |
| ISO 1717:1974 | Connecting dimensions of rods and bit shanks for rotary drilling. It does not define carbide chemistry or a mining grade. | Confirm the button grade, profile, fit and acceptance separately. |
| ISO 1718:1991 | Rod dimensions and tapered connections for percussive drilling; not a carbide-grade specification. | The connection standard does not replace the bit, button or material drawing. |
| ISO 10208:1991 | Dimensions and tolerances of left-hand rope threads for percussive drilling equipment; not the composition of carbide buttons. | Thread conformity does not establish tool-body or hardmetal interchangeability. |
| ISO 4489:2019 | Sampling and testing of hardmetals for physical and mechanical properties. Agree the lot, specimens and acceptance criteria. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 4506:2018 | Strength and proof stress under uniaxial compression of cemented carbides. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 3369:2006 | Density measurement for impermeable sintered metals and hardmetals. It is a test method, not a density requirement for every grade. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 3327:2009 | Transverse rupture test for hardmetals with negligible ductility. Significant plastic deformation restricts use to comparisons; revision is in development. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 4499-1:2020 | Metallographic assessment of hardmetal microstructure using photomicrographs. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 4499-2:2020 | Metallographic WC grain-size measurement, principally for WC-Co hardmetals. It is not a universal grain-size method for every cermet. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 4499-4:2016 | Metallographic examination of porosity, free carbon and eta phase in hardmetals. Acceptance limits must be agreed separately. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |
| ISO 28079:2026 | Palmqvist indentation toughness test for hardmetals and cermets at room temperature. The 2026 edition replaces 2009; it is not a universal service-life guarantee. | Agree the grade, specimens, test conditions and acceptance values. A laboratory method does not prove service performance. |

Grade Verification and Approval
A manufacturer grade, ВК designation, WC-Co description and laboratory property set are different types of information. MNK-G.S.A records the relation being proposed and does not declare a direct equivalent unless the chemistry, binder, grain-size, properties, manufacturing route and application evidence support that conclusion.
See the ВК / WCo / YG Grade Verification guide for the controlled cross-reference method. Final approval remains tied to the drilling duty, equipment reference and agreed trial or qualification route.
Inspection and Traceability
- Carbide batch identity and declared composition or grade document
- Density, hardness, rupture strength, toughness or microstructure results where specified
- Button or insert dimensions, profile, surface condition and visual inspection
- Steel-body material, heat treatment and dimensional records for assemblies
- Retention or joining controls and any customer-defined qualification test
- Lot marking, packing and traceability through prototype and repeat supply
Use the separate Cemented Carbide Inspection and Test Methods guide to select compatible methods and reporting requirements. Acceptance values must come from the governing drawing, purchase specification or approved qualification plan.
