0.0354" (0.90mm) x .120" LOC Kyocera 2-Flute Square End Carbide End Mill, 1/8" Shank | M205

0.0354" (0.90mm) Kyocera 2-Flute Square End Carbide End Mill – M205

This Kyocera Series 1600 precision solid carbide end mill features a 0.90mm (.0354") cutting diameter, .120" (3.05mm) 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, and fine-detail cutting where a small, accurate cutting diameter is required.

Manufacturer part number: 1600.0354.120. This tool belongs to Kyocera's Series 1600, developed for precision milling and routing of printed circuit boards, plastics, soft materials, and suitable soft metals.

The 2-flute up-cut spiral with a 30° helix angle helps direct chips away from the cutting area. Its solid carbide construction provides rigidity and wear resistance, while the square-end geometry is useful for slotting, pocketing, profiling, and producing flat-bottom features.

Common Applications

• Precision CNC milling and fine-detail machining
• Narrow slots, pockets, and profiles
• Printed circuit board milling and routing

Specifications

Precision Micro-Machining Considerations

At only 0.90mm diameter, this end mill requires accurate toolholding, minimal spindle runout, rigid workholding, and appropriate cutting parameters. Use suitable spindle speeds and light cutting engagements to limit deflection and breakage.

For precision slotting, verify the required slot width and material compatibility before machining. Cutting conditions should be selected according to the workpiece material, machine rigidity, and tool engagement.

For instrument making, miniature inlay work, and other specialty applications, this tool may be useful where a narrow, flat-bottom cutting profile is required.
