Product description

TiSiN solid carbide ball nose end mill · 2 flutes

For 3D contour and surface milling on CNC machines

A solid carbide ball nose end mill with two flutes and a TiSiN coating, designed for 3D contour and surface milling on CNC machines. The rounded cutting tip has a spherical radius R.

Select the variant by its cutting diameter, ball radius, shank diameter and overall length. These are separate dimensions: tools with the same cutting diameter may have different shanks or lengths. The variant designation and its dimension card show the exact combination.

1. Ball nose milling applications

Operation	Role of the ball nose geometry
3D surface milling	Machining freeform surfaces with successive toolpaths. The ball radius is one of the dimensions to enter when defining the tool geometry in CAM.
Contour milling	Machining curved surfaces and rounded features. Select the ball size for the workpiece geometry and access to the machining area.
CNC milling	Machining with a programmed toolpath. Enter the dimensions of the exact tool variant that will be mounted in the spindle.

The designation R identifies the radius of the spherical tip. It is not a small corner radius on a flat end mill. Before running the program, check that a ball nose tool has been selected in the CAM library and that its diameter and radius match the actual tool.

2. Construction and specifications

Parameter	Value or meaning
Tool type	Solid ball nose end mill
Tool material	VHM — solid carbide
Coating	TiSiN — titanium silicon nitride
Number of flutes	2 — designated 2T
Tip geometry	Spherical, with radius R
Cutting diameter	1–20 mm, depending on the variant
Ball radius	R0.5–10 mm, depending on the variant
Shank diameter	3–20 mm, depending on the variant
Overall length	50, 60, 75, 100, 150 or 200 mm, depending on the variant
Shank type	Cylindrical

The ranges describe the tool family. Not every cutting diameter is available with every overall length or shank diameter. Check the product selector for available combinations. The diameter of the ball section is twice its radius: Ø = 2 × R.

3. Workpiece materials

The application range includes the material groups below. Cutting conditions must account for the specific grade, material condition and operation; a material group alone does not determine spindle speed or feed rate.

Material group	Examples and scope
Steels	Steel and hardened steel. Account for the actual workpiece hardness when selecting the tool and cutting conditions.
Stainless steels	Stainless steel machining with conditions selected for the particular grade and milling operation.
Superalloys and heat-resistant materials	Select for the specific alloy and setup; do not apply one set of cutting conditions to every material in this group.
Non-ferrous metals	Aluminium, copper and brass.
Plastics and non-metallic materials	PLEXI, PVC, POM, PE and plywood. Match the machining conditions to the specific material and required workpiece geometry.

4. Understanding the variant dimensions

Example designation: Ø5xR2.5x6Dx50L. It describes a 5 mm cutting diameter, a 2.5 mm ball radius, a 6 mm shank and a 50 mm overall length. All dimensions are in millimetres.

Element	Meaning	Value in the example
Ø5	Cutting diameter	5 mm
R2.5	Radius of the spherical tip	2.5 mm
6D	Shank diameter	6 mm
50L	Overall tool length	50 mm

Variant designations may use a decimal point while the Polish dimension cards use a comma: R2.5 and R2,5 identify the same radius. In these designations, the letter D after a number refers to the shank diameter.

The cutting diameter and shank diameter may differ. In this example, the cutting section is 5 mm in diameter but the holder must suit a 6 mm shank. Do not select a collet solely from the first dimension in the designation.

5. Selecting diameter, radius and length

Check radius R. Compare the spherical tip with the workpiece geometry and the tool definition in CAM. Do not confuse the radius with the cutting diameter.
Select the cutting diameter. Account for access to the machining area and clearance for the tool and shank. Check the full designation of the chosen variant.
Check the shank diameter. Match the holder to the value followed by D. This dimension may differ from the cutting diameter.
Select the overall length. Choose a tool that provides the required access. Once mounted, limit stick-out to the reach needed for the operation.
Compare the dimension card and selector. Check all four dimensions before ordering. The selected variant shows its current price and availability.

Overall length L is not the length of cut or the permissible milling depth. Actual reach after clamping also depends on tool stick-out and clearance between the holder, shank and workpiece.

The photographs on the dimension cards are illustrative. Select dimensions from the labels and variant designation; the photograph is not a scale drawing. This also applies to tools with the same cutting diameter and different overall lengths.

6. Tool holding and machining setup

The tool is intended for CNC machines with a suitable spindle and tool holder. Before machining, check tool seating and runout. Do not transfer cutting settings automatically between variants with different diameters and lengths.

Check clamping and runout. Correct any seating problem before cutting. Inspect the cutting section and make sure the shank is properly clamped.
Minimise stick-out. Extend the tool only as far as the operation requires, while maintaining correct shank engagement in the holder.
Account for a long stick-out in the settings. If longer reach is necessary, adjust spindle speed, feed and tool load accordingly. A longer tool does not imply that the settings for a short tool can be used unchanged.
Respond to vibration. If vibration or irregular cutting occurs, check tool holding and cutting conditions before continuing.

A handheld drill or low-speed bench drill does not replace a CNC milling machine for this operation. Selecting spindle speed, feed and stock allowance requires information about the workpiece material, cutting diameter, toolpath and actual stick-out.

The quantity field specifies the number of individual tools in the chosen size. Different dimensions shown in the gallery illustrate available tool versions; they do not mean that all sizes are supplied as one set.

8. Frequently asked questions

What does R3 mean?

R3 identifies a spherical tip with a 3 mm radius. The corresponding ball section is 6 mm in diameter. Read the shank diameter and overall length separately from the variant designation.

Does a 5 mm cutter always have a 5 mm shank?

No. This family also includes tools with a cutting diameter smaller than the shank. Select the holder using the dimension marked D rather than the cutting diameter alone.

Does 200L mean a 200 mm length of cut?

No. 200L specifies the overall tool length. It does not define the cutting length or the permissible depth of a single pass.

Can I determine the size from the photograph?

The photograph is illustrative. The labelled dimensions and variant designation define the size. Before ordering, compare the cutting diameter, radius R, shank diameter and overall length.
