FAQ

Questions Buyers Ask

How do I choose between 2-flute and 4-flute end mills?

2-flute end mills have larger flute spaces for chip evacuation — best for aluminum and soft materials, slotting and roughing. 4-flute end mills have more cutting edges for higher feed rates and better surface finish — best for steel and stainless steel. 3-flute is a compromise favored for aluminum finishing.

What coating should I choose for stainless steel?

TiAlN or AlCrN coatings perform well in stainless steel due to their high heat resistance and oxidation stability. For aluminum, uncoated or a polished TiB2/AlTiN coating prevents built-up edge.

Can you make custom carbide end mills?

Yes — long neck, stub flute, tapered, form and T-slot cutters per your drawings. Custom tools typically ship in 15-30 days depending on complexity and quantity.
