Product description

GFN / GSFN inserts for disc cutters

Parting-off and grooving · carbide · pack of 10 inserts

GFN / GSFN indexable inserts are intended for disc cutters used for parting-off and grooving. Mechanical seating in the cutter allows a worn insert to be replaced. Selection depends on the complete insert designation, its width and a grade suitable for the workpiece material.

The range includes GFN replacement inserts in grade JTS2456 and ISCAR inserts. The grade is included in the selected variant name. Each pack contains 10 inserts of the selected variant.

1. Applications and workpiece materials

GFN 2.0J and GFN 3.0J in grade JTS2456 are intended for standard parting-off and grooving of structural, carbon and low-alloy steels with a hardness of up to approximately 30 HRC.

For stainless steels, including 304 and 316, heat-resistant steels and difficult-to-machine or higher-hardness materials, a suitably selected ISCAR GSFN version is recommended. The standard JTS2456 replacement may have a limited tool life in these applications. The approximate 30 HRC limit stated for JTS2456 does not automatically apply to the other grades.

2. Construction and specifications

Feature	Description
Tool type	Indexable insert for a disc cutter
Insert material	Carbide
Operations	Parting-off and grooving
Seating	Mechanical, in a matching cutter pocket
GFN replacement grade	JTS2456
ISCAR grades in this range	IC328 / IC908 — as specified in the variant name
Sales unit	Pack of 10 inserts of one variant

3. GFN JTS2456 replacement dimensions

CW cutting width and R corner radius relate to a specific insert geometry. The values below apply to GFN JTS2456 replacement inserts; visual similarity alone does not establish the dimensions of another insert.

Designation	Cutting width CW	Corner radius R
GFN 2.0J	2.0 mm	0.2 mm
GFN 3.0J	3.0 mm	0.25 mm

4. Insert selection and cutter compatibility

Compare the insert designation specified for the cutter with the full variant name. The family, width and geometry version all matter. JTS2456, IC328 or IC908 identifies the selected insert grade and does not replace the geometry designation.

For disc cutters in this family: ISCAR GFN 3 and ISCAR GSFN 3 are not interchangeable designations. Do not select ISCAR GFN 3 for a cutter specified for the indicated GSFN 3 insert solely because both names refer to a 3 mm width.

Selection check	What to compare
Insert family	The complete designation required by the cutter, including GFN / GSFN and the code suffix
Width	The CW dimension for the selected version
Grade	JTS2456, IC328 or IC908 and its application to the workpiece material

5. Pack contents

You are purchasing 10 inserts of the same selected variant. The photographs show one insert to display its geometry. The insert mounting key is sold separately.

6. Questions before ordering

Is the price for one insert?

The sales unit is a pack of 10 inserts of the selected variant.

How do GFN 2.0J and GFN 3.0J in grade JTS2456 differ?

They have different cutting widths and corner radii: 2.0 mm / R0.2 mm and 3.0 mm / R0.25 mm, respectively. Choose the geometry that matches the cutter pocket.

Which version should I choose for stainless steel?

For stainless steels, including 304 and 316, a suitably selected ISCAR GSFN version is recommended. JTS2456 replacements are intended for the standard structural, carbon and low-alloy steel applications described above.
