Product description
1. SlotCut Basic JP indexable slitting cutter
SlotCut Basic JP is an indexable slitting cutter for cutting-off operations. It uses replaceable solid carbide (VHM) inserts, mechanically seated in the body pockets. Inserts are installed using the appropriate assembly key.
The selected variant defines the cutting diameter, cutting width, number of teeth and mounting arrangement. The range includes cylindrical-shank cutters, cutter-and-FMB-arbor assemblies, and separately selected arbors and keys. Cutting inserts and the assembly key are sold separately from the cutter.
| Parameter | Information |
|---|---|
| Tool type | Indexable slitting cutter for cutting-off |
| Series | SlotCut Basic JP |
| Cutting elements | Replaceable solid carbide (VHM) inserts |
| Cutter body alloy | 42CrMo alloy steel |
| Insert mounting | Mechanical seating in body pockets |
2. Configurations and mounting
Choose a configuration for the holder fitted to the machine. Cutter diameter is different from shank diameter and mounting bore diameter. Each is labelled separately on the variant card.
| Configuration | Meaning | Check |
|---|---|---|
| Cylindrical shank | The cutting head is connected to a shank of the specified diameter. | Shank diameter d, length L and neck dimensions. |
| Cutter + FMB mounting arbor | A cutter disc with a matched mounting arbor. | Cutting diameter D, width ap, bore d and assembly mounting. |
| Mounting arbor | A separate component connecting a suitable cutter disc to the holder. | Connection diameters and arbor length, not just cutter diameter. |
| Assembly key | A separate tool for installing inserts in their pockets. | The selected key type and its designation. |
Match the cylindrical shank to a suitable clamping holder, such as an ER holder. For a Weldon holder, check both the diameter and the clamping surface configuration of the specific shank. An FMB assembly and a cylindrical-shank cutter use different holder connections.
3. Technical drawing symbols
The drawing shows symbols; the table below gives the values in millimetres. Drawings are illustrative and must not be used to measure proportions. Read each symbol in the context of the component shown on that card.
| Symbol | Cylindrical-shank cutter | Cutter disc or arbor |
|---|---|---|
| D | Cutter cutting diameter. | On a disc card: cutting diameter. On an arbor card: body or shank diameter, as labelled. |
| ap | Cutting width. | Disc cutting width; different from diameter and body thickness h. |
| d | Cutter shank diameter. | On a disc card: mounting bore diameter. |
| L | Overall cutter length. | On an arbor card: the indicated body length. |
| d1 | Neck diameter behind the cutting head. | On a mounting module card: mounting bore diameter. |
| L1 | Neck length. | Shown on the cylindrical-shank cutter drawing. |
| D1 | — | On a disc card: hub diameter. |
| h | — | On a disc card: body thickness. |
| d2 | — | On an arbor card: locating spigot diameter. |
The Ø symbol means diameter. Neck dimensions d1 and L1 describe a different part of the tool from shank diameter d and overall length L. Do not interchange them when selecting a holder or checking available working space.
4. Reading the cutter designation
For example, JP 045*2.0-C20T4-120 identifies a cutter with a 45 mm cutting diameter, 2.0 mm cutting width, Ø20 mm shank, four teeth and 120 mm overall length.
| Code element | Meaning in the example |
|---|---|
| JP | Cutter series designation. |
| 045 | Ø45 mm cutting diameter. |
| 2.0 | 2.0 mm cutting width. |
| C20 | Ø20 mm cylindrical shank diameter. |
| T4 | Number of teeth: 4. |
| 120 | 120 mm overall length. |
Disc designations also include a bore code, such as K22 for a Ø22 mm bore. FMB identifies the mounting arrangement. Arbor codes are model designations: read their dimensions in the specific card table instead of transferring values from another component code.
5. Selecting cutting inserts
Match the insert to the cutting width and pocket of the selected cutter. The complete designation matters: similar codes do not necessarily identify the same fit. Each variant card states the primary insert type for that tool.
| Cutting width | Primary insert type | Compatible ISCAR designation |
|---|---|---|
| 2.0 mm | GFN 2.0J, grade JTS2456 | GFN 2J |
| 3.0 mm | GFN 3.0J, grade JTS2456 | GSFN 3 |
ISCAR GFN3, without the S in GSFN, is not compatible with this cutter. For the 3.0 mm configuration, distinguish the GFN 3.0J insert from its ISCAR GSFN 3 counterpart. The ISCAR insert grade is a separate element of its designation.
The number of teeth T specifies the number of inserts needed to populate the cutter. Inserts shown in illustrations demonstrate their position in the pockets; they are not included with the cutter body.
6. Arbors and mounting modules
Separately offered arbors have their own dimension cards. Compare the diameters of the components being connected. Matching the disc outside diameter alone does not confirm that its bore matches the arbor spigot.
| Arbor card parameter | Meaning for selection |
|---|---|
| Body or shank diameter D | Outside diameter of the indicated arbor section. |
| Body length L | Length indicated by dimension line L. |
| Mounting bore d1 | Bore diameter at the holder connection, where that bore is present in the module. |
| Locating spigot d2 | Diameter of the section that centres the cutter disc. |
| Listed cutter diameters | The model application designation; the actual connections still need to match. |
Before combining a disc with a separately purchased arbor, check the disc mounting bore and locating spigot diameter. A cylindrical arbor and a module with a mounting bore are different components; one component’s dimensions do not define the other’s.
7. Variant contents and assembly key
| Selected item | Contents |
|---|---|
| Cylindrical-shank cutter | Cutter body with shank. Inserts and the assembly key are purchased separately. |
| Cutter + FMB arbor | Cutter with the arbor specified in that variant. Inserts and the assembly key are purchased separately. |
| Separate arbor | The mounting component described and dimensioned on its card. |
| Standard key JP-D20-120 | Tool steel key for insert installation. |
| Premium key | Tool steel key with replaceable carbide pins. |
Use the appropriate key when seating inserts and avoid excessive force. Overloading or incorrect use can damage the key or insert; on the standard key, it can deform the pins. The Premium version has replaceable pins.
The key is not included in a cutter assembly. Select it as a separate item. Likewise, selecting a separate arbor does not mean purchasing a complete cutter.
8. Questions and answers
Are inserts and the key included?
No. They are sold separately from the cutter body or cutter-and-arbor assembly.
Do ap and h mean the same dimension?
No. ap is cutting width; h on a disc card is the cutter body thickness.
Does ISCAR GFN3 fit the 3.0 mm version?
No. The specified counterpart is ISCAR GSFN 3. The primary insert designation on the cutter card is GFN 3.0J.
How do I read dimensions when the drawing has only letters?
Find the same symbol in the table below the picture. Its full label is followed by the value in millimetres.
Is disc diameter enough to choose an arbor?
No. Also check the disc bore, locating spigot and arbor-to-holder connection. The selected component cards give these dimensions.
