0.0312" (1/32") x .157" LOC 2-Flute Ball Nose Carbide End Mill, 1/8" Shank – MB-130

This solid carbide ball nose end mill features a 0.0312" (1/32") cutting diameter, .157" length of cut, 2-flute spiral geometry, ball nose cutting profile, 1.50" overall length, and a standard 1/8" shank. It is designed for CNC contouring, profiling, 3D detail work, engraving, and small-radius finishing applications.

The ball nose geometry is useful for rounded profiles, 3D carving, relief work, mold-style detail, and finishing passes where a square end tool would leave sharper steps or corners. The small 1/32" diameter makes it suitable for fine detail work where a larger cutter would not fit.

The 2-flute up-cut spiral design helps clear chips from the cut while maintaining a practical balance of cutting strength and chip evacuation. Use proper feeds, speeds, shallow step-downs, secure workholding, and good chip clearing when machining with a micro end mill this small.

Common Applications

• 3D carving and contouring
• Fine detail CNC machining
• Relief carving and rounded detail work
• Small-radius profiling
• Finishing passes after roughing
• Plastic, acrylic, and composite machining
• Wood detail cutting
• Jewelry, wax, model-making, and small precision work

Benefits

• Ball nose geometry is useful for 3D contours, rounded profiles, and fine finishing work
• Small 1/32" cutting diameter is suitable for detailed CNC features
• 2-flute spiral design supports chip evacuation in many CNC applications
• Up-cut geometry helps pull chips up and away from the cut
• Solid tungsten carbide construction provides rigidity and wear resistance
• Center-cutting design allows plunge-style entry when used properly
• Standard 1/8" shank fits many compact CNC routers and precision collet setups

Specifications

Ball nose note: Ball nose end mills are designed for rounded profiles, 3D contouring, and finishing work. For flat-bottom slots or pockets, choose a square end mill instead.
