Micro Long-Neck Ball Nose End Mill | R0.1–R1.5

Micro Long-Neck Ball Nose End Mill

Solid-carbide micro ball nose end mill for precision contouring, rib machining, deep cavities and fine finishing on CNC milling machines. The long-neck design provides additional reach while the small ball radius supports detailed 3D surfaces and narrow features.

Key Features

• Micro ball-nose geometry for small-radius and detailed contour machining
• Long-neck design for ribs, narrow pockets and deep cavities
• Solid carbide construction
• Wide range of ball radii and neck-length combinations
• Suitable for finishing and light precision milling when the correct grade and cutting conditions are selected

Size & Variant Guide

Variants are mainly identified by ball radius and neck/effective length. A typical format is:

R0.5 × 8H

• R0.5 = 0.5mm ball radius
• 8H = 8mm neck/effective length as listed for the variant

Smaller radii and longer neck lengths require greater care because tool rigidity decreases as the tool becomes smaller and longer.

Typical Applications

• Deep-cavity finishing
• Mold and die contour machining
• Rib and narrow-slot finishing
• Small-radius 3D surfaces
• Precision detail machining

How to Select

1. Choose the required ball radius from the drawing or target surface geometry.
2. Select the shortest neck length that can reach the machining area.
3. Confirm shank size and overall tool geometry are compatible with the holder and machine.
4. Match the grade/coating option to the workpiece material and machining conditions.

Machining Guidance

Micro long-neck tools are sensitive to runout, vibration and excessive tool overhang. Use a rigid machine setup, a high-precision holder or collet, minimal runout and conservative cutting engagement. As neck length increases, reduce cutting load accordingly.

Important Note

Exact radius, neck length, grade, coating and stock status vary by variant. Confirm the selected specification before ordering.

FAQ

What does R mean in the variant name?
R indicates the ball radius of the cutter.

What does H mean?
H indicates the neck or effective reach dimension used in the variant naming.

Should I choose the longest neck available?
No. Use the shortest neck that can safely reach the feature. A shorter neck normally provides greater rigidity.

What is this tool mainly used for?
It is intended for detailed contouring, rib machining, deep cavities and precision finishing where a small ball radius and extended reach are required.

Original Product Notes

Micro Long-Neck Ball Nose End Mill

Solid-carbide micro ball nose end mill for precision rib, deep-cavity, contour and finishing work on CNC milling machines.

Key Features

• Micro ball-nose geometry for detailed contouring and small-radius machining.
• Long-neck design provides additional reach for ribs, pockets and deep cavities.
• Multiple carbide grades and coating options are available for different workpiece materials.
• Suitable for precision machining of steel, stainless steel, aluminum, copper and other compatible materials when the correct grade is selected.

Size Format

Variants are specified by ball radius, neck length / working length and overall tool geometry. R indicates ball radius, while H indicates the effective neck or working length on applicable variants.

Use Guidance

For micro tools, use a rigid machine, high-precision collet and minimal tool overhang. Reduce speed, feed and depth of cut when using longer reach or when machine rigidity is limited.

Note: Exact coating, grade, radius and neck dimensions vary by variant. Confirm the selected specification before ordering.
