Milling Cutter: FAQ

How do I ensure the shank size fits my machine?

Always verify the shank diameter in millimeters (mm) rather than relying on generic terms. AliExpress listings usually provide detailed technical drawings; cross-reference these with your collet size to avoid compatibility issues.

How can I tell if a cutter is genuine tungsten carbide?

Check the HRC (Rockwell Hardness) rating in the product description. High-quality carbide cutters typically range from HRC45 to HRC65; lower prices often indicate HSS with a coating rather than solid carbide.

What coating should I look for for long-lasting performance?

Look for AlTiN or TiAlN coatings for high-temperature resistance and longevity. These coatings significantly reduce wear during high-speed machining compared to uncoated bits.

How are these precision tools protected during international shipping?

Most reputable sellers use individual plastic protective tubes for each cutter to prevent edge chipping. Review the 'Customer Photos' section to confirm the seller uses sturdy, padded packaging.

Recommendations for buyers

✓
Material Grade
Choose Tungsten Carbide for longevity and high-speed applications, or HSS for cost-effective, general-purpose tasks on softer materials.
✓
Flute Count
Select 2-flute cutters for better chip evacuation in soft materials like aluminum, and 4-flute versions for finer finishes in harder metals.
✓
Helix Angle
Opt for a 35-degree or 45-degree helix angle to balance cutting force and surface quality depending on your specific machining speed.
✓
Coating Type
Select specialized coatings like DLC for aluminum or TiSiN for hardened steel to maximize tool life and heat resistance.
