Milling cutters, ground to the geometry you specify

Millcrown is a sourcing desk for solid carbide and HSS milling cutters: square, ball nose, bull nose, roughing, tapered and chamfer end mills, slot drills, face mills and thread mills. Standard catalog items ship boxed; OEM programs are ground to your drawing in the Changzhou cutting-tool cluster. Every figure comes back in writing.

Spec sheets, not sales talk

Geometry in writing

Every program starts with a spec sheet: diameter, length of cut, overall length, shank, flute count, helix, corner radius, substrate, coating, marking, packing. Speeds and feeds stay engineering talk - the site keeps starting-point references, and your real numbers come from your machine and your setup. The desk's job is to make sure the sheet the factory quotes is the sheet you approved.
