Grey cylindrical carbide end mill with four spiral flutes and AlTiN coating

YINGHUA

YINGHUA 14x14x45x100MM 4 Flutes HRC45 Altin Coated Carbide Roughing End Mill

SKU CH-2M6N-HZR4W

A 4-flute solid carbide roughing end mill with Altin coating for aluminium, cast iron, steel, stainless steel and copper

  • Product typeRight-Angle Drills
  • 4-flute design enables faster material removal in roughing passes
  • HRC45 solid carbide withstands high cutting forces on steel and cast iron
  • Altin coating reduces friction and extends tool life in abrasive alloys
  • 14 mm diameter with 45 mm flute length suits deep pocket milling
  • 100 mm overall length provides reach for extended CNC operations

14 mm solid carbide roughing end mill

This 14 mm diameter solid carbide roughing end mill is built for CNC milling of aluminium cast iron steel stainless steel and copper. Its four-flute geometry and HRC45 substrate suit machine shops and fabricators who need fast material removal in medium-hard metals.

Altin coating and separate packaging

The Altin coating reduces friction and heat buildup during aggressive roughing passes extending tool life in abrasive alloys. Each cutter ships in its own package with colour chosen at random so operators can identify and store individual tools without confusion.

Limits of the HRC45 substrate

The HRC45 hardness ceiling means the tool will wear quickly on hardened steels above that level or on exotic super-alloys. Users needing finish passes or tighter tolerances must follow with a dedicated finishing cutter because this rougher leaves a coarse surface.

Questions about this item

How often will the AlTiN coating on this 4-flute roughing end mill need to be replaced?

The AlTiN coating wears gradually during use; plan to replace the cutter once the coating is visibly depleted or cutting performance drops on aluminium, cast iron, steel, stainless steel or copper.

What limit appears first when running this 14 mm diameter end mill continuously in steel?

The HRC45 carbide substrate reaches its hardness limit first, so sustained cutting in steel will dull the flutes before heat becomes the primary constraint.

How much heat and noise does this solid carbide roughing end mill generate during all-day CNC milling?

Heat builds steadily in the 100 mm length of cut during prolonged roughing passes; use flood coolant to control temperature and expect typical high-speed spindle noise levels.
