1 Scope
This part of ISO 5611 applies for cartridges type A, with hole(s) for fastening screw(s), of style G, i.e.
with cutting edge angle κ r = 90° for side cutting.
Cartridges are intended to be used with indexable inserts made of hard metal, ceramic or other cutting materials and are primarily mounted to be used for internal turning of operations.

EXAMPLE Cartridge with screw clamping through hole (S) triangular indexable insert shape (T), cartridge style G (G), for the insert normal clearance 7° (C), right hand cartridge (R), with height h 1 = 12 mm (12), cartridge Type A (CA), length l 1 = 55 mm (–), edge length l 4 = 16,5 mm (16) is designated as follows:
Cartridge ISO 5611–3 – STGCR 12CA – 16
5 Material
Steel with a tensile strength of at least 1 200 N/mm 2 .
6 Design
6.1 Method of holding
(first letter symbol identifying the method of holding the insert)
6.1.1 Cartridge for indexable inserts with insert normal clearance α n = 7°
(fourth symbol identifying insert normal clearance C)
— holding screw clamping through hole; letter symbol S, e.g. SCGCR.
6.1.2 Cartridge for indexable inserts with insert normal clearance α n = 11°
(fourth symbol identifying insert normal clearance P)
— holding with top clamping; letter symbol C, e.g. CTGPR;
— holding screw clamping through hole; letter symbol S, e.g. SCGCR.
6.1.3 Cartridge for indexable inserts with insert normal clearance α n = 0°
(fourth symbol identifying insert normal clearance N)
— holding with hole clamping; letter symbol P, e.g. PTGNR.
6.2 Corner radius r ε
Cartridges in accordance with this part of ISO 5611 can be equipped with indexable inserts with cutting edge lengths l 4 as specified in Table 1 and any corner radius r ε .
The values for l 1 given in Table 1 apply to cartridges with indexable inserts having corner radii r ε in accordance with Table 2.
For cartridges with indexable inserts with corner radii other than those specified in Table 2, the dimensions for f and l 1 shall be determined in accordance with ISO 5611-1.
The tolerances on h 1 and f refer to dimensions measured with master indexable insert and master shim, if any.BS ISO 5611-3 pdf download.
