0.1575" (4.00mm) x .330" LOC AlTiN Coated 2-Flute Ball Nose Carbide End Mill, 5/32" Shank | MB-260

0.1575" (4.00mm) x .330" LOC AlTiN Coated Ball Nose Carbide End Mill, 4mm Shank – MB-260

This AlTiN coated solid carbide ball nose end mill features a 0.1575" (4.00mm) cutting diameter, .330" length of cut, 2-flute spiral geometry, 45° helix angle, 2.00" overall length, and a 4.00mm shank. It is designed for CNC milling, contouring, profiling, 3D carving, and detail work where a rounded cutting profile is required.

The ball nose geometry is useful for 3D surfacing, rounded profiles, mold-style work, relief carving, and finishing passes where a square end tool would leave sharper steps or corners. The 2-flute up-cut spiral design helps clear chips while maintaining a practical balance of cutting strength and chip evacuation.

The AlTiN coating provides added wear resistance compared with uncoated carbide and can be useful in appropriate metalworking and higher-friction cutting applications. Use proper feeds, speeds, workholding, and chip clearing for your material and machine.

Common Applications

• 3D carving and contouring
• Ball nose profiling
• Relief carving and rounded detail work
• Mold-style machining
• Finishing passes after roughing
• Plastic, acrylic, and composite machining
• Aluminum and suitable soft non-ferrous metals
• Light-duty steel or harder-material work when proper setup, feeds, speeds, and lubrication/coolant are used

Benefits

• Ball nose geometry is useful for 3D contours, rounded profiles, and finishing work
