Indexable carbide inserts for CNC and VMC work, held in ready stock and sold wholesale. Pick by the operation you are running, then by the material group you are cutting.
01 — By operation
Five families, with the insert designations stocked against each one.
01 — Turning
Negative and positive inserts for external and internal turning on CNC lathes — roughing through to final passes, in the standard ISO shapes and clamping styles.
Insert models
02 — Grooving / Parting
Parting blades and grooving inserts for cut-off, external and internal grooves, face grooving and circlip seats, in a range of widths and depths of cut.
Insert models
How they are specified
Unlike turning inserts (CNMG, DNMG, VNMG, etc.), grooving and parting inserts are generally blade-type inserts rather than standard ISO polygonal inserts. They are identified mainly by:
03 — Milling
Indexable inserts for VMC and milling work — round inserts for copy and profile milling, rectangular and parallelogram inserts for face, shoulder and high-feed cutters.
Insert models
Common milling operations and insert types
| Operation | Insert types |
|---|---|
| Face milling | SPMT, SEKT, SNMX, ONMU |
| 90° shoulder milling | APKT / APMT, XDKT |
| High-feed milling | LNMU, RDMT, RPKT |
| Copy / profile milling | RDMT, RPMT, round inserts |
| Heavy roughing | SNMX, ONMU, XNMU |
04 — Finishing
Sharp-edged, close-tolerance geometries for the last cut — light depths of cut and low feed forces, where surface finish and size control matter more than removal rate.
Insert models
Common finishing geometries
05 — Threading
Full-profile and partial-profile inserts for external and internal thread generation, covering metric, ISO and common pipe and UN thread forms.
Insert models

| Internal metric threading | 16IR ISO, 16IR AG60 |
| Unified (UNC / UNF) | 16ER UN, 16IR UN |
| BSP pipe threads | 16ER BSPT, 16IR BSPT |
| NPT pipe threads | 16ER NPT, 16IR NPT |
| Trapezoidal threads | 16ER TR, 16IR TR |
| ACME threads | 16ER ACME, 16IR ACME |
02 — By workpiece grade
Colour coded to ISO 513 — the same colours printed on the insert boxes, so a shelf matches a row.
Carbon, alloy and tool steels. Long chipping, high cutting forces.
Austenitic and duplex stainless. Work hardening and built-up edge.
Grey, nodular and malleable iron. Short chipping and abrasive.
Aluminium, copper, brass and bronze. Sharp edges, high speeds.
Hardened and chilled steels, roughly 45 HRC and above.
