Product description

Solid carbide dovetail end mill — 4 flutes — TiSiN

Dovetail slot milling and chamfering · angles 30°, 45°, 60°, 75° · cylindrical shank

This four-flute solid carbide dovetail end mill is intended for milling dovetail slots and undercuts and for chamfering. The enlarged cutting head, relieved neck and cylindrical shank form a monolithic solid carbide tool. Select the size by cutting diameter, cutter angle and overall length.

This listing includes TiSiN-coated cutters, primarily intended for machining steel.

Available size range: cutting diameter Ø1.5–20 mm; overall length 50, 60, 65 or 75 mm; cutter angles 30°, 45°, 60° and 75°. Available dimension combinations are shown in the size selector. Read shank and neck dimensions from the card for the selected cutter.

1. Solid carbide construction and cutting portion finish

The tool is made of solid carbide, designated VHM, with a grain size of 0.6 µm. Four flutes are ground in the cutting portion. The cylindrical shank is held in a tool holder matched to its diameter.

Feature	Specification
Tool type	Shank-type dovetail end mill
Tool material	VHM — solid carbide
Carbide grain size	0.6 µm
Number of flutes	4
Cutting portion finish	TiSiN
Shank	Cylindrical
Geometry	Enlarged cutting head and relieved neck
Sales unit	1 piece of the selected cutter

Grain size describes the structure of the tool material. Cutter angle is a separate cutting geometry parameter stated in the size designation. These two properties describe different characteristics.

The cutting portion has chip flutes. Its construction includes a negative rake angle and an enlarged core. Select the coating finish and size before establishing cutting conditions for the particular component.

2. Workpiece materials

Main applications include carbon steel, tool and mould steel, pre-hardened steel, and stainless steel. Applications also include non-ferrous materials, including aluminium. Consider the exact material grade and heat-treatment condition when selecting the cutter.

Material	Application
Carbon steel	Dovetail slot milling and chamfering.
Tool and mould steel	Machining slots and surfaces with geometry corresponding to the cutter angle.
Pre-hardened steel	Match cutting conditions to the actual condition of the workpiece material.
Stainless steel	Machining with cutting conditions matched to the particular grade.
Non-ferrous materials, including aluminium	An additional application group for the TiSiN cutter.

Workpiece material is independent of the diameter and angle designation. Cutters with the same dimensions can require different cutting conditions for different materials. Compare the applications of the selected finish with the material used in the operation.

3. Dovetail slots and chamfering

The cutting head shape enables dovetail slot and undercut milling. Its angled cutting edges are also used for chamfering. Select the appropriate variant by comparing diameter and angle with the component drawing.

Operation	Parameters to compare
Dovetail slot	Cutting head diameter, cutter angle and clearance for the relieved neck.
Undercut in a slot	Space for cutting head entry and access to the angled surface.
Chamfering	Cutter angle and cutting diameter appropriate to the required surface.

Available cutter angles are 30°, 45°, 60° and 75°. The angle designates a specific variant geometry. When comparing with the component drawing, also use the diagram for the selected size, which shows where the stated angle is located.

Diameter specifies the size of the enlarged cutting head. The relieved neck has a separate diameter and length. When planning an undercut, check both neck dimensions rather than treating them as equal to cutting diameter or overall length.

4. Family dimensions

Parameter	Range or way to read it	Relevance to selection
Cutting diameter	Ø1.5–20 mm	Size of the enlarged cutting head.
Cutter angle	30°, 45°, 60° or 75°	Geometry of the angled cutting portion.
Overall length	50, 60, 65 or 75 mm	Length from shank end to the front of the cutting head.
Shank diameter	Stated on the individual variant card	Dimension required for holder selection.
Neck diameter and length	Stated on the individual variant diagram	Clearance between the cutting head and shank.
Number of flutes	4	The flute count for this family.

The letter L in the code specifies overall length. It does not describe cutting edge length, neck length or permissible machining depth. Not every diameter, angle and length combination is available; choose an available size in the selector.

Do not determine shank diameter from the first number in the code alone. The first number specifies cutting diameter. Confirm the clamping diameter in the Shank diameter field on the card for the selected tool.

5. Reading the size designation

The example 6×60°×50L contains three values: cutting diameter, cutter angle and overall length. These parameters appear in the same order throughout the family.

Code element	Meaning	Example value
6	Cutting diameter	Ø6 mm
60°	Cutter angle	60°
50L	Overall length	50 mm

The example variant has a Ø6 mm shank. Shank diameter is an additional dimension on the card and does not appear as a separate element in the abbreviated code. Every cutter in this family has four flutes, as confirmed in the final row of its card.

The size code selects geometry and length. TiSiN coating is a feature of this listing. Workpiece material selection requires a separate comparison with the application range.

6. Relieved neck and clearance

A relieved neck lies between the enlarged cutting head and cylindrical shank. Its dimensions are shown on the variant diagram. Separate diameter and length labels allow access to the machining area to be checked.

Example for Ø6 mm cutting diameter, 60° cutter angle and 50 mm overall length: neck diameter is Ø3 mm and neck length is 8 mm. These dimensions apply to this particular variant and must not be transferred to other diameters or angles.

Compare neck diameter with slot clearance and neck length with the distance between the cutting head and an obstruction. When checking access, also consider the larger shank diameter and the space occupied by the holder.

The 8 mm neck length in the example is separate from the 50 mm overall length. Neck length does not designate active cutting edge length. It is stated directly beside the corresponding dimension line on the variant card.

7. Selection and machine clamping

The cutters are intended for CNC machining centres and engraving machines equipped with a suitable spindle and tool holder. Match the cylindrical shank to the collet or clamping bore diameter. Checking shank diameter is separate from selecting cutting diameter.

Material: compare the application range of the selected finish with the workpiece material.
Geometry: choose diameter and angle with reference to the slot or chamfer drawing.
Access: check overall length and both relieved neck dimensions.
Clamping: confirm cylindrical shank diameter and holder compatibility.
Variant: compare the selected size designation with its card and the planned operation.

Access to the machined surface depends on the complete cutter and holder assembly. Overall length in the code does not by itself specify overhang after clamping. When planning movement, compare the position of the cutting head, neck and shank with the component geometry.

8. Frequently asked questions

What does VHM mean?

VHM denotes solid carbide. The cutting portion and shank form a monolithic tool.

How many flutes does the cutter have?

Four. This flute count applies throughout the family and is stated in the last row of the variant card.

Does 50L mean cutting length?

50L means an overall length of 50 mm. Neck length and cutting portion dimensions must be read separately.

Is shank diameter always equal to cutting diameter?

Select the holder using the Shank diameter field on the card. The abbreviated size code does not contain a separate shank dimension.

Does every size have a Ø3 × 8 mm neck?

These dimensions apply to the example with Ø6 mm cutting diameter, 60° cutter angle and 50 mm overall length. Check the individual diagram for another size.
