Product description

MFH03 high-feed cutter for LOGU030310 inserts

Cylindrical shank · 42CrMo body · high-feed roughing

MFH03 is an indexable milling cutter with a cylindrical shank, intended for high-feed roughing. The body uses LOGU030310 inserts. Select the required cutting diameter, shank diameter, overall length and number of insert pockets.

The family includes cutting diameters from Ø16 to Ø35 mm and overall lengths of 120, 160 and 200 mm. The exact dimensions of each version are stated in its designation and on its variant card. The body is made from 42CrMo steel and the shank is hardened.

1. Construction and technical specifications

The tool has a cylindrical shank and a cutting head with pockets for replaceable inserts. Flutes in the cutting section provide space for chip evacuation. The number of pockets depends on the selected version and is identified by the 2T, 3T, 4T or 5T suffix.

Parameter	Specification
Family	MFH03 indexable high-feed cutter
Insert system	LOGU030310
Tool mounting	Cylindrical shank
Body material	42CrMo
Shank construction	Hardened
Cutting diameter	Ø16–35 mm, depending on the variant
Shank diameter	Ø15–32 mm, depending on the variant
Overall length	120, 160 or 200 mm
Number of insert pockets	2, 3, 4 or 5, as stated in the variant designation

The shank and cutting diameters may differ. Use the shank diameter when selecting a toolholder and the cutting diameter when planning the toolpath. These dimensions are not interchangeable.

2. Application and the high-feed principle

MFH03 is intended for rough milling at high feed rates. High-feed machining combines a high feed per tooth with a shallow axial depth of cut. Cutting conditions must be selected for the actual insert, workpiece material and rigidity of the setup.

The high-feed designation does not specify one spindle speed or feed rate for every tool size. A change in diameter, insert count or tool overhang requires the machining conditions to be checked again.

Process element	Selection consideration
Roughing	Removal of machining allowance in successive passes
High feed rate	Selected together with depth of cut and insert geometry
Workpiece material	Determines the required LOGU030310 insert grade and geometry
Chip evacuation	Consider the head flutes and the space available in the workpiece

3. Selecting the diameter, shank and length

First check the cutting diameter needed for the operation. Then select the shank to suit the toolholder and the length needed to reach the machining area. Use the shortest practical overhang that provides the required access without collision.

Dimension	What it describes	What to check
Cutting diameter	Size of the cutting section	Access to the machining area and the toolpath
Shank diameter	Size of the section held in the toolholder	Compatibility with the holder or collet clamping range
Overall length	Length from the cutting head to the end of the shank	Required reach and the length clamped inside the holder
Pocket count	Number of inserts working in the tool	Consistency with the designation and feed calculation

Overall length is not the same as tool overhang. Part of the shank remains clamped in the toolholder. Check access for the complete assembly: cutting head, shank, toolholder and workpiece fixture.

The tool diagrams are illustrative. Do not measure dimensions from the image proportions; use the dimensions stated for the selected variant.

4. Reading the MFH03 designation

The size code states the family, shank diameter, cutting diameter, overall length and pocket count, in that order. The letter C relates to the shank. The final number followed by T identifies the number of cutting positions.

Designation element	Meaning
MFH03	Cutter family and tool system
C + number	Shank diameter in millimetres
Next number	Cutting diameter in millimetres
Following number	Overall length in millimetres
2T / 3T / 4T / 5T	Number of insert pockets in the body

5. LOGU030310 inserts and pocket count

Select the cutter for the LOGU030310 insert system. Before installation, check the complete insert designation, geometry and fit in the pocket. A similar external shape does not establish compatibility of another insert.

The 2T–5T designation refers to the cutting positions in the body, not the number of usable edges on a single insert. Use a consistent set of inserts when selecting or replacing them.

Item to check	Selection rule
Insert designation	LOGU030310 system suited to the cutter pocket
Grade and geometry	Matched to the workpiece material and operation
Body population	Consistent with the pocket count in the variant code
Pocket and fastening	Clean seating surfaces and correctly seated inserts

6. Mounting and preparation

Check the selected shank diameter and choose a suitable toolholder or collet.
Clean the shank, pockets and insert seating surfaces before assembly.
Clamp the tool over the length required by the toolholder. Keep overhang as short as practical while retaining the required access.
Check insert seating, fastening condition and consistency of the insert designations.
Verify the toolpath for the complete assembly, including the toolholder and workpiece fixture.

A longer body allows the reach to be selected for the task, but the rigidity of the complete setup must be considered. Conditions suitable for a short setup are not automatically suitable for a longer overhang.

7. Selecting cutting conditions

Select cutting speed, feed and depth of cut for the installed LOGU030310 insert, workpiece material, cutting diameter and mounting conditions. Values for another insert grade or cutter are not ready-to-use settings for this version.

Use the correct number of cutting positions when calculating table feed. Changing from 2T to 3T, 4T or 5T changes the relationship between feed per tooth and feed per minute.

During initial machining, observe load, chip evacuation and cutting stability. Adjust conditions for the actual tool assembly and workpiece material instead of using one setting for the whole family.

The MFH03 body selection determines the tool geometry and mounting. Cutting data are selected for the actual insert and process.

8. Frequently asked questions

Is the shank diameter always equal to the cutting diameter?

No. The family includes versions with different shank and cutting diameters. The first number after C identifies the shank diameter; the next identifies the cutting diameter.

What does 3T or 5T mean?

It means three or five insert pockets in the body. It does not specify the number of spare inserts or the number of edges on one insert.

Does an overall length of 200 mm provide 200 mm of working reach?

No. This is the overall tool length. Actual reach also depends on the shank length clamped inside the holder and access to the workpiece.

Which inserts fit MFH03?

The cutter is intended for the LOGU030310 system. Select the complete insert designation, grade and geometry to suit the pocket and workpiece material.
