Product families built around applications—not only ISO codes.
Turning, milling, grooving, drilling and non-standard carbide inserts, supported by a clean grade architecture and controlled technical recipe.
Standard families plus project-based equivalents
Final recommendation is confirmed by cutter compatibility, workpiece material, machining severity and test result.
We separate the insert geometry, chipbreaker and carbide grade. This makes the product easier for distributors to sell and easier for GUTEC to control across qualified sources.
Check availability
Turning inserts
Core ISO geometries for steel, stainless, cast iron and hard-material applications—from finishing to heavy roughing.
Core geometries
CNMG / CNMM, DNMG, TNMG, WNMG, SNMG, CCMT, DCMT and VBMT.
Application window
Continuous and interrupted cutting; semi-finishing, general machining and roughing.
Project customization
Chipbreaker, edge preparation, coating, substrate and drawing-based equivalents.
Milling inserts
Compatibility with the cutter body must be confirmed before a mass quotation.
- Face milling: general and rough milling for steel, stainless and cast iron.
- Round inserts: RCKT and R300-style equivalents for profiling and heavy cutting trials.
- Shoulder milling: APMT, SEKT and SDMT-style inserts depending on cutter body.
- Special geometry: drawing and sample confirmation before tooling commitment.
Grooving, drilling and specials
Availability is project-specific and depends on geometry, coating, MOQ and drawing confirmation.
MGMN · MGGN · MRMN
Standard and custom widths, chipbreakers and edge-preparation options.
WCMX · SPMG · U-drill
Indexable drilling insert families for distributor projects and replacement trials.
Drawing · sample · private code
Reverse-engineered equivalents with confidential internal version control.
GUTEC grade architecture
A public grade can be paired with an internal source/version code—for example, GTP35C-A01—to preserve traceability.
| ISO | Material | Light / finishing | General | Heavy / roughing | Coating / note |
|---|---|---|---|---|---|
| P | Steel | GTP15C | GTP25C | GTP35C | CVD / PVD options |
| M | Stainless steel | GTM15P | GTM25P | GTM35P | PVD preferred |
| K | Cast iron | GTK10C | GTK20C | GTK30C | Application verified |
| S/H | HRSA / hard materials | Project | GTS20P / GTS25P | GTH25P / Project | Application verified |
Indicative architecture. Final grade, chipbreaker and coating recommendation must be confirmed by application conditions and test result.
An insert is a complete system
Changing one layer can change tool life. GUTEC therefore manages the complete recipe rather than only the outer brand name.
Substrate
Hardness · TRS · grain sizeControls the toughness and wear foundation.
Coating
CVD · PVD · TiAlN · AlTiNControls heat resistance, abrasion and adhesion.
Edge preparation
Honing · chamfer · polishControls chipping, burrs and built-up edge.
Geometry
Chipbreaker · rake · clearanceControls chip flow, cutting force and surface finish.
