0.1181" (3.00mm) x 8mm LOC AlTiN Coated 4-Flute Square End Carbide End Mill, 4mm Shank | M4-125

This 3.00mm 4-flute solid carbide end mill features a square end, AlTiN coating, and a 55-degree high-helix cutting geometry. The 8mm length of cut provides a useful balance of reach and rigidity for small-diameter milling, profiling, finishing, and detail work in CNC applications.

The AlTiN coating helps improve wear resistance and heat resistance when cutting steels, stainless steels, and other harder materials. The 4-flute square-end design is well suited for finishing passes, light slotting, contouring, and precision work where a clean flat-bottom cut is needed.

Typical Applications

• Precision CNC milling and profiling
• Small-detail machining
• Finishing passes in steels, stainless steels, and other harder materials
• Flat-bottom pocketing and contour work
• Model making, mold work, prototype work, and small-part machining

Benefits

• AlTiN coating helps improve heat and wear resistance in demanding materials.
• 4-flute geometry provides a strong cutting edge layout for finishing and light milling operations.
• 55° high-helix design supports smoother cutting action and improved finish quality in suitable applications.
• 8mm LOC gives more reach than the smaller sizes while still keeping the tool relatively rigid.
• 4mm shank provides a larger holding diameter than the cutting diameter for improved support.
