INDEXABLE INSERTS & CUTTING TIPS
Cemented Carbide Indexable Inserts and Cutting Tips
Technical sourcing of cemented-carbide inserts and cutting tips for turning, boring, milling, drilling, threading, grooving, parting and special machining operations.
MNK-G.S.A reviews the complete insert requirement: geometry, dimensions, holder interface, workpiece, operation, cutting conditions, substrate, coating, edge preparation, quantity and approval route. A familiar shape code or application colour does not by itself identify a technically interchangeable product.
Insert and Tip Sourcing Scope
Indexable Inserts
Positive or negative inserts, single- or double-sided configurations, fixing-hole variants and application-specific geometries for standard or approved tool systems.
Brazed Cutting Tips
Standard or drawing-based hardmetal tips supplied for brazing into turning, milling, boring, woodworking or special-purpose tool bodies.
Special Inserts and Preforms
Custom grooves, profiles, holes, chip-forming features and near-net geometries reviewed against a revision-controlled drawing and final finishing route.
What Defines an Insert
| Specification layer | Information to identify | Why it matters |
|---|---|---|
| Standard designation | Shape, clearance angle, tolerance class, type, size, thickness and corner radius within the applicable designation systemISO 1832:2017; ISO 3364:2017; ISO 6987:2012 | The code identifies specified geometric features, not the complete commercial product. |
| Holder interface | Pocket, seat, screw or clamp, right/left-hand orientation and dimensional fit | Similar-looking inserts may not locate or clamp correctly in a particular holder. |
| Cutting geometry | Chipbreaker, rake angle, edge land or chamfer, edge rounding, wiper geometry and edge condition | These features affect cutting forces, chip formation, edge strength and attainable surface finish. |
| Substrate and material grade | Carbide family, binder, grain size, hardness-toughness balance and manufacturer designationSandvik Coromant: cutting-tool materials | Proprietary grades in the same application group are not automatically interchangeable. |
| Coating and treatment | Coated or uncoated condition, coating process, layer system and specified post-treatmentSandvik Coromant: cutting-tool materials | The substrate, coating and edge preparation must be assessed together for the intended operation. |
| Machining duty | Workpiece material, operation, interruption severity, speed, feed, depth of cut, coolant and machine stability | Distinguish finishing, medium machining, roughing and interrupted cutting; use the exact manufacturer recommendations. |
Geometry, grade, coating and holder compatibility require separate confirmation. An application group is not a grade-equivalence statement. Table review date:
A full order reference may contain both standardized and manufacturer-specific elements. MNK-G.S.A verifies which part of the designation controls geometry and which part identifies proprietary grade, chipbreaker or coating.
Standards Used in Insert Specification
- ISO 1832:2017 provides a designation code for common indexable-insert types. The official ISO record states that the edition was confirmed in 2022.
- ISO 3364:2017 addresses dimensions for a defined family of rounded-corner hardmetal inserts with cylindrical fixing holes and zero normal clearance.
- ISO 6987:2012 addresses dimensions for rounded-corner hard-material inserts with a partly cylindrical fixing hole.
- ISO 10910:1995 establishes a general format for approximate chip-control zones; it is a preselection framework, not a product-specific cutting recommendation.
- ISO 513:2012 classifies hard cutting materials by machining application. Its P, M, K, N, S and H logic must not be treated as chemical grade identity.
A standards reference cannot confirm holder compatibility, proprietary chipbreaker geometry, coating, grade performance or suitability for the intended machining process. The exact current edition and the complete manufacturer or customer requirement remain controlling.
Application and Grade Selection
Workpiece and Operation
- Exact alloy, condition, hardness and surface condition
- Turning, milling, drilling, threading, grooving or parting
- Finishing, medium machining or roughing duty
- Continuous, variable or interrupted engagement
- Required surface finish, dimensional stability and burr control
Machine and Cutting Conditions
- Holder, tool body, overhang and setup rigidity
- Cutting speed, feed and depth of cut
- Coolant strategy and available delivery pressure
- Machine power, spindle condition and vibration exposure
- Observed wear, chipping, built-up edge or thermal damage
The selection balance changes with the process. A sharper edge may reduce cutting force but provide less edge security; a stronger edge preparation can tolerate heavier loading while increasing force. Substrate, geometry, coating and cutting data therefore need to be evaluated together.
Controlled Sourcing Routes
Exact Identified Product
Source against the complete current manufacturer code, holder system, revision or catalogue reference when substitution is not permitted.
Approved Technical Alternative
Compare geometry, interface, grade, coating, edge preparation and application data; obtain customer or process-owner approval before use.
Custom Tip or Insert
Develop a drawing-based blank, brazed tip or finished insert through controlled prototype, inspection and application-validation stages.
Why Shape or Colour Is Not Enough
- Two inserts with the same basic ISO shape may use different tolerances, holes, chipbreakers, edge preparations and holder interfaces.
- An ISO 513 application group describes intended machining use rather than a single composition or universal performance level.
- Manufacturer grade codes are proprietary; an advertised cross-reference requires engineering review and application validation.
- ВК, WCo, YG and ТК designations identify different material-reference traditions and cannot be converted into a finished-insert grade solely from their names.
- A coating family or similar colour does not establish identical layer structure, substrate, edge condition or tool life.
Cemented Carbide Insert RFQ Checklist
- Complete insert or tip designation
- Manufacturer, catalogue or drawing reference
- Holder or tool-body identification
- Required substrate, grade and coating
- Chipbreaker, edge preparation and corner radius

For a requested alternative, attach photographs of the insert and packaging, both sides of the insert, the holder pocket, the full code and any available cutting-data or failure information.

Review limits: Review covers designation, geometry and preliminary application scopes in the listed public ISO descriptions. Grade, coating, chipbreaker, holder fit and cutting parameters still require the exact manufacturer specification. Manufacturer material descriptions are general context, not product approval.
- ISO 1832:2017
Designation system for indexable inserts. A designation alone does not confirm substrate grade, coating or holder compatibility.
- ISO 3364:2017
Dimensions of rounded-corner hardmetal inserts with a cylindrical fixing hole and 0° normal clearance. This is a specific insert geometry, not all inserts.
- ISO 6987:2012
Rounded-corner hard-material inserts with a partly cylindrical fixing hole. Verify the applicable shape and fastening system.
- ISO 10910:1995
Format for presenting approximate chip-control zones for preliminary selection. It does not supply application-specific cutting parameters.
- 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.
