0.0197" (0.50mm, Approx. .020") x .118" LOC 2-Flute Square End Carbide End Mill, 1/8" Shank | M105

0.50mm (.0197", Approx. .020") 2-Flute Square End Carbide End Mill – M105

This Kyocera solid carbide micro end mill features a precision 0.50mm (.0197") cutting diameter, .118" length of cut, 2-flute square end geometry, 1.50" overall length, and a standard 1/8" shank. It is designed for precision CNC milling, narrow slots, profiling, contouring, and fine-detail machining where additional cutting reach is needed.

Size note: The nominal cutting diameter is 0.50mm (.0197"), approximately .020" (20 mils). The .020" designation is a rounded size reference rather than the exact nominal cutting diameter.

The .118" flute length provides additional cutting reach compared with shorter 0.50mm end mills, making this tool useful for small slots, profiles, and features requiring greater cutting depth. Longer cutting sections are more susceptible to deflection, so appropriate machining parameters and controlled cutting forces are important.

The 2-flute up-cut geometry helps evacuate chips during precision machining. Solid carbide construction provides rigidity and wear resistance, while the square end geometry is suitable for miniature slots, pockets, profiles, and flat-bottom features.

This end mill can be used for detail machining in plastics, acrylic, wood, fiberglass, composites, and selected soft non-ferrous metals such as aluminum and brass when appropriate feeds, speeds, workholding, and machine rigidity are maintained.

Specifications

Choosing the Right 0.50mm Flute Length

We offer 0.50mm diameter 2-flute square end mills with different cutting lengths to suit your machining requirements:

• M105ST – .030" LOC: Stub-length design for shallow cuts and reduced cutting-section deflection.
• M105A – .079" LOC: Intermediate cutting reach for general precision detail machining.
• M105 – .118" LOC: Longer cutting section for applications requiring additional reach.

When possible, select the shortest flute length that accommodates the required cutting depth to help minimize tool deflection.

Additional Specialty Applications

This 0.50mm carbide end mill may also be useful for instrument makers, luthiers, model makers, jewelry work, miniature components, and other precision applications requiring narrow CNC cuts. Always verify the required slot width, material suitability, machine rigidity, and tool runout before machining.

For customers selecting tooling for precise instrument-related grooves, see our CNC Fret Slotting End Mills Collection. Confirm the required slot width before selecting a cutter.

Important Micro-Machining Considerations

At just 0.50mm diameter, this end mill is delicate. Successful machining requires rigid workholding, precision toolholding, minimal spindle runout, appropriate spindle speed, conservative cutting depths, and carefully selected feed rates. The longer .118" cutting section requires particular attention to cutting forces and tool deflection. Excessive loading may cause premature breakage.
