Product description

MNR solid carbide micro tool

MNR is a family of solid carbide micro tools for rough 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

Rough 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	Rough 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	MNR
Tool material	Solid carbide
Machining operation	Rough 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

MNR 3R0.1 L10

Parameter	Value for the example
Shank diameter D	Ø3 mm
Overall length L1	50 mm
Machining depth L2	10 mm
Dimension F	2.9 mm
Dimension R	0.1 mm
Cutting depth S	0.3 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 MNR 3R0.1 L10.

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	Rough 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.
