0.1250" (1/8") x .670" LOC 2-Flute Ball Nose Carbide End Mill, 1/8" Shank | MB-220

0.1250" (1/8") x .670" LOC 2-Flute Ball Nose Carbide End Mill, 1/8" Shank – MB-220

This solid carbide ball nose end mill features a 0.1250" (1/8" / 3.175mm) cutting diameter, .670" length of cut, 2-flute spiral geometry, 1.50" overall length, and a standard 1/8" shank. It is designed for precision CNC contouring, 3D profiling, relief carving, and machining curved or radiused features.

The ball nose cutting profile is useful for creating smooth 3D surfaces, rounded contours, fillets, and detailed finishing passes. Its 2-flute up-cut spiral design helps evacuate chips upward during cutting while providing a practical balance of chip clearance and cutting strength.

The extended .670" LOC provides additional cutting reach compared with shorter 1/8" ball nose end mills. This makes MB-220 useful for deeper contours, taller relief features, and workpieces requiring more flute engagement than standard shorter-flute cutters.

Manufactured from solid tungsten carbide, this tool offers rigidity and wear resistance for detailed CNC work. Its bright, uncoated cutting edges can be used in wood, plastics, acrylic, machining wax, and suitable soft non-ferrous metals when proper cutting parameters, chip evacuation, and workholding are used.

Common Applications

• 3D contouring and CNC profiling
• Relief carving and detailed engraving work
• Curved surfaces, fillets, and rounded features
• Mold, model, and prototype machining
• Wood carving and decorative CNC routing
• Plastic, acrylic, and machining wax cutting
• Aluminum, brass, and suitable soft non-ferrous metals
• Deeper contouring and finishing operations requiring extended flute length

Benefits

• Ball nose geometry produces smooth curved contours and radiused features
• Extended .670" LOC offers more cutting reach than shorter 1/8" ball nose tools
• 2-flute design balances cutting strength and chip clearance
• Up-cut spiral geometry helps move chips away from the cutting area
• Solid carbide construction provides rigidity and wear resistance
• Uncoated cutting edges offer versatility for suitable materials
• Standard 1/8" shank fits many CNC routers, precision spindles, and collet systems

Specifications

Extended-Flute Machining Considerations

With a .670" cutting length and 1/8" diameter, this ball nose end mill provides useful reach but has less cutting-section rigidity than shorter-flute alternatives. For best results, use rigid workholding, minimal tool extension from the collet, and suitable stepovers and cutting depths. Avoid excessive side loading, especially when machining deeper contours or tougher materials.
