Indexable Insert Selection — Quick Reference (Carbide Cutting)
Indexable inserts = replaceable carbide cutting tips for turning + milling + boring + threading + parting. When one edge wears, index to fresh edge — or replace whole insert — without disturbing the tool holder setup. Production economics + repeatability advantage over brazed/regrindable tooling.
| Insert Shape (ISO Code) | Cutting Edges per Insert | Best For |
|---|---|---|
| Triangular (T) | 3 edges | Turning + boring — most common workshop shape |
| Square (S) | 4 edges | Heavy stock removal + roughing |
| Diamond / Rhombic 80° (C) | 2 edges (per side) | Versatile turning — facing + profiling |
| Diamond / Rhombic 55° (D) | 2 edges | Profile turning + tight corner work |
| Diamond / Rhombic 35° (V) | 2 edges | Detailed profile turning |
| Round (R) | Infinite (continuous edge) | Plunge + contour + die finishing — strongest edge |
| Trigon (W) | 3 edges | Heavy roughing — stronger than triangular |
| Carbide Grade (P10-P40) | For steel | P10 finish / P30 medium / P40 roughing |
| Carbide Grade (M10-M40) | For stainless | Per cutting condition |
| Carbide Grade (K10-K40) | For cast iron | Per condition |
| Carbide Grade (N10-N40) | For aluminium + non-ferrous | Sharp + polished — NEVER coated |
| Coating (TiN / TiCN / TiAlN / nACo) | Per material | Match coating to substrate |
Critical: ISO insert code (e.g. TNMG160404) encodes shape + clearance + tolerance + size + chipbreaker — match EXACTLY to tool holder pocket. Insert + holder are SYSTEM. Grade vs material: P series for steel | M for stainless | K for cast iron | N for non-ferrous (Al/brass) | S for heat-resistant superalloys | H for hardened. Brands: SECO, Sutton Tools, OSG. Companion: all inserts, milling inserts, lathe tooling, machining.
Indexable Inserts
Indexable inserts are replaceable carbide cutting tips used in turning, milling, boring, threading and parting operations. When one cutting edge wears, the insert is indexed to a fresh edge — or replaced entirely — without disturbing the tool holder setup. This makes indexable tooling faster to change and more consistent in production environments than brazed or regrindable tools.
SECO Indexable Inserts
AIMS stocks SECO indexable inserts across turning, milling, threading and parting/grooving applications. SECO is a Swedish precision tooling manufacturer with a strong global reputation in high-performance machining. The AIMS range covers the most common ISO turning insert styles and milling insert profiles used in general engineering and production machining.
Turning Inserts
SECO turning inserts are available in CCMT, DCMT, TCMT, WNMG and TNMG ISO shapes, covering the majority of general turning, facing, boring and profiling operations. Chip former styles include F1 (precision/finishing), MF2 (medium finishing) and M3 (medium roughing). The TP25 carbide grade is a general-purpose PVD-coated grade suited to steel and stainless turning. HX grade covers heat-resistant alloys and difficult materials.
Milling Inserts
SECO milling inserts cover face milling, shoulder milling and high-feed milling applications. Correct insert selection for milling depends on entry angle, depth of cut, workpiece material and the specific SECO cutter body in use — contact AIMS for assistance matching inserts to your existing toolholders.
Threading and Parting/Grooving Inserts
Thread turning inserts are used in CNC lathes to produce precision internal and external threads. Parting and grooving inserts handle cutoff and groove turning operations with controlled chip formation. Both are available as part of the SECO range stocked by AIMS.
Insert Identification
ISO insert designation codes describe the insert shape, clearance angle, tolerance, hole type, size, corner radius, chip former and coating. For example, CCMT 09T304 MF2 TP25 defines a 80° diamond shape (C), 7° clearance (C), medium tolerance (M), through-hole (T), 9.525mm IC (09), 3.97mm thick (T3), 0.4mm corner radius (04), MF2 chip former, TP25 grade. When ordering replacements, cross-reference the full designation from your existing insert or toolholder documentation.
