0.0315" (0.80mm, Approx. 1/32") x .157" LOC 2-Flute Square End Carbide End Mill, 1/8" Shank | M107

0.80mm (.0315", Approx. 1/32") 2-Flute Square End Carbide End Mill – M107

This Kyocera solid carbide precision end mill features a 0.80mm (.0315") cutting diameter, .157" 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 slotting, profiling, pocketing, and detailed machining where small features and controlled cutting are required.

Size note: The nominal cutting diameter is 0.80mm (.0315"), approximately 1/32". A true 1/32" diameter is .03125", so this tool is slightly larger. For precise slots or features, use the nominal 0.80mm / .0315" diameter when selecting tooling.

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

The .157" flute length provides useful cutting reach for small features requiring more depth than shorter micro end mills. Appropriate cutting parameters and controlled tool engagement remain important for minimizing deflection.

This end mill is suitable 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

Additional Specialty Applications

This 0.80mm carbide end mill may also be useful for instrument makers, luthiers, model makers, jewelry work, and other precision applications requiring narrow CNC cuts. For fret slotting or other precision slotting work, always confirm the required slot width and account for the difference between 0.80mm and an exact 1/32" cutter.

See our CNC Fret Slotting End Mills Collection for additional options.

Important Machining Considerations

Although larger than extremely small micro cutters, this 0.80mm end mill still requires careful machining. Use rigid workholding, precision toolholding, minimal spindle runout, appropriate spindle speed, controlled cutting depths, and carefully selected feed rates. Excessive cutting forces or tool deflection may cause premature breakage.
