0.0500" (1.27mm) x .075" LOC 2-Flute Stub Length Square End Carbide End Mill, 1/8" Shank | M050ST

0.0500" (1.27mm) 2-Flute Stub Length Square End Carbide End Mill – M050ST

This 0.0500" (1.27mm) solid carbide end mill features a short .075" length of cut, 2-flute square end geometry, 1.50" overall length, and a standard 1/8" shank. Its stub-length cutting section is well suited for shallow precision CNC milling, narrow slots, miniature profiles, and detailed machining where cutting-section rigidity is important.

Compared with longer-flute tools of the same cutting diameter, the .075" stub-length cutting section helps reduce deflection during shallow machining operations. This makes it a practical choice when precision and control are more important than extended cutting reach.

The 2-flute up-cut spiral geometry helps evacuate chips upward and away from the cutting area. Solid carbide construction provides rigidity and wear resistance, while the square end geometry is suitable for small slots, pockets, profiles, contours, and flat-bottom features.

This tool 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 machining conditions are maintained.

Specifications

Why Choose a Stub-Length End Mill?

Stub-length end mills feature shorter cutting sections than longer-flute tools of comparable diameter. This helps reduce cutting-section deflection and can improve control when machining shallow features. The tradeoff is reduced cutting reach, making stub-length tools particularly useful when rigidity and precision are more important than cutting depth.

Important Machining Considerations

Although its short .075" cutting section improves rigidity compared with longer-flute tools, this 1.27mm carbide end mill still requires appropriate machining conditions. Use rigid workholding, precision toolholding, minimal spindle runout, suitable spindle speeds, conservative cutting depths, and carefully selected feed rates. Excessive cutting forces or tool deflection may cause premature breakage.
