Product description
MTR solid carbide micro tool
MTR is a family of solid carbide micro tools for internal turning. Version selection includes the complete option code, cutting geometry, holding dimensions and the reach required for the intended operation. Individual versions in the family can have different dimensions and different field designations in their diagrams.
Compare each option with its own card. Dimensions for one version do not automatically describe the other tools in the family.
Application
- Internal turning using the appropriate cutting portion.
- Selecting a tool for the workpiece geometry and access to the machining area.
- Comparing the selected version dimensions with the requirements of the particular workpiece.
| Machining feature | Selection factor |
|---|---|
| Machining operation | Internal turning |
| Cutting portion | Geometry and dimensions specified for the particular version |
| Machining area | Access and reach required by the chosen workpiece |
Workpiece material, tool geometry and holding arrangement affect the choice of operating conditions. The dimensional example identifies a version; it is not a cutting-speed or feed-rate chart.
Construction and specification
| Feature | Details |
|---|---|
| Tool family | MTR |
| Tool material | Solid carbide |
| Machining operation | Internal turning |
| Construction | Single-ended tool with a cutting portion and shank |
| Version selection | Complete option code in the product selector |
The complete option designation identifies the version being ordered. When comparing two tools, consider every part of the code and the corresponding dimensions. A right-hand, left-hand or double-ended version, where available in the selector, must suit the tool setup in the machine.
Dimensions of an example option
MTR 8R0.2 L50 100L (przedłużony)
| Parameter | Value for the example |
|---|---|
| Shank diameter D | Ø8 mm |
| Overall length L1 | 100 mm |
| Machining depth L2 | 50 mm |
| Dimension F | 7.9 mm |
| Dimension R | 0.2 mm |
| Cutting depth S | 1.2 mm |
The table applies only to the illustrated option. For a different code, use the card assigned to that version.
Understanding the dimensions
Each field in the example below has its own label and value. Read the symbol together with the dimension description. Distinguish cutting-portion dimensions, holding dimensions, overall length and working reach because they serve different selection purposes. This table applies only to option MTR 8R0.2 L50 100L (przedłużony).
| Designation / feature | Role in selection | What to check |
|---|---|---|
| L1 | Length of the complete tool | Available tool space and the holding arrangement |
| L2 | Working dimension shown on the card | Required reach for the particular operation |
| d / D / F | Different geometrical fields depending on the family | The relevant label on the selected tool card |
| Cutting portion | Separate dimensions in the example option table | Workpiece geometry and the requirements of the particular operation |
Read each dimension symbol together with its label. The same symbol can have a different meaning in another micro-tool family.
Selecting the tool for the operation
| Step | Selection | Comparison |
|---|---|---|
| 1 | Tool family and geometry | Internal turning |
| 2 | Cutting-portion dimensions | Values beside the appropriate card symbols |
| 3 | Dimension L2 | Required reach, distinguished from overall length L1 |
| 4 | Version and holding arrangement | Compatibility of the selected tool, toolholder and intended operation |
Selection should account for access to the machining area. Overall length alone does not define machining depth; the relevant working dimension and compatibility with the holding arrangement must also be considered.
Holding and using the option card
Match the tool to its holder using the holding portion and dimensions of the selected version. Check the position of the cutting portion relative to the workpiece, the working length and the space required by the rest of the tool.
The card shows the complete tool. The photograph and annotations are illustrative and are not a scale drawing. Read the numerical dimension values rather than measuring the image on screen. The option name identifies the version being ordered.
Frequently asked questions
Does L1 define machining depth?
L1 identifies the overall length. Working dimension L2 and the cutting geometry are separate information.
Does a symbol always have the same meaning?
No. Use the label for the particular family and option. Do not transfer the meaning of F or d between different tools.
Can I determine a size by measuring the photograph?
No. The photograph is illustrative. Use the stated numerical dimension values for selection.
Which version will be ordered?
The version selected in the product options. Compare its full code with the option card title and values.
