The full code can contain up to 13 symbols, but the first are mandatory for standard turning inserts. Core Designation Breakdown (Positions 1–7) Common Examples 1. Shape The outline geometry of the insert.
(0°/Neutral), C (7°), P (11°). Neutral inserts are double-sided; positive inserts are single-sided. 3. Tolerance Allowable deviation in dimensions. The full code can contain up to 13
(Standard/Medium), G (Ground/High Precision), E (Precision). 4. Fixation Clamping method and chipbreaker info. (0°/Neutral), C (7°), P (11°)
The designation system is a standardized alphanumeric code used to identify the geometric and physical characteristics of indexable turning inserts. This "license plate" for inserts ensures that tools from different manufacturers (like Sandvik Coromant , Seco Tools , or Kennametal) are interchangeable and clearly specified. Tolerance Allowable deviation in dimensions
(Hole + Chipbreaker), W (Hole + Double-sided chipbreaker), A (Hole, no chipbreaker). 5. Size Length of the cutting edge. Represented in mm (Metric) or 1/8" increments (ANSI/Inch). 6. Thickness Vertical depth of the insert. 04 (4.76 mm), 03 (3.18 mm), 06 (6.35 mm). 7. Radius Nose radius for surface finish. 04 (0.4 mm), 08 (0.8 mm), 12 (1.2 mm). Extended Parameters (Positions 8–13) ISO designation for Inserts - Seco Tools
(80° Diamond), D (55° Diamond), T (Triangle), W (Trigon), S (Square), R (Round). 2. Clearance The relief angle behind the cutting edge.
