CNC cutting tool for micro-milling that aims to deliver accurate, clean cuts for shallow grooves and side milling. Designed for hobby machinists and small workshops who want burr-free finishes on steels and cast iron. Can sourcing map Square Nose End Mill meet durability and finish expectations under regular use?
⚡ At a Glance
- • Cutting Quality: Sharp square end with 4-flute spiral geometry for fine surface finishes
- • Best for: Hobby machinists and small workshops working on carbon steel and cast iron
- • Not ideal for: Heavy roughing of large stock or high-volume production runs
Solid carbide construction and an AlTiN composite coating increase hardness and heat resistance. A 2mm cutting diameter and 4mm shank suit precise shallow-groove and side-milling tasks.
Precise micro-grooves – with a 2mm tip diameter
Cutting diameter measures 2mm with a cutting flute length of 6mm and a 4mm shank, overall length 50mm. HRC45-rated cutting hardness gives rigidity needed for small-diameter milling.
Accurate, narrow grooves and tight-radius side milling become feasible, helping achieve repeatable dimensions in small parts and prototypes.
Cleaner chip evacuation – with 4-flute spiral and 35 degree helix
Four flutes combine with a 35 degree spiral angle and spiral chip space design to guide swarf away from the cutting edge. The square end geometry maintains a defined corner for finishing passes.
Fewer recuts and improved surface finish result, reducing manual deburring and speeding up finishing on shallow profiles.
Longer life under speed – with solid P05 carbide and AlTiN coating
P05-grade solid carbide offers high hardness, wear resistance and heat resistance, while the AlTiN composite coating reduces oxidation wear and boosts surface hardness at temperature.
Higher permitted spindle speeds and better wear resistance lead to fewer tool changes and greater confidence when tackling tougher alloys.
✨ The 4 Key Reasons for sourcing map Square Nose End Mill
- AlTiN composite coating - Increased wear resistance at elevated cutting temperatures for longer life
- 2mm cutting diameter - Enables precise micro-grooves and tight-radius side milling
- 4mm shank - Stable clamping reduces chatter during high-speed passes
- 4-flute spiral geometry - Faster chip evacuation and smoother surface finishes in light cuts
