YINGHUA 20x20x45x100MM HRC45 Altin Coated 4 Flutes Solid Carbide Roughing End Mill

SKU CH-BW3B-2721J

A 4-flute solid carbide roughing end mill with Altin coating for milling aluminium, steel and stainless steel up to HRC45 hardness

  • Product typeRight-Angle Drills
  • Altin coating extends tool life in abrasive materials
  • Four-flute design improves chip evacuation during heavy roughing
  • Solid carbide construction maintains rigidity at HRC45 hardness
  • Suitable for aluminium, cast iron, steel, stainless steel and copper
  • 20 mm shank, 45 mm flute and 100 mm overall length fit standard holders

20 mm HRC45 Altin Roughing End Mill

This 20 mm diameter solid carbide roughing end mill carries an Altin coating and a four-flute design rated for materials up to HRC45 hardness. It is intended for CNC milling of aluminium cast iron, steel, stainless steel and copper alloys where high metal-removal rates are required.

Separate packaging per cutter

Each unit ships in its own randomly coloured package so the cutter arrives protected and ready for tool-holder loading. The individual wrap prevents edge damage during transit and keeps the coating clean until first use.

Check shank fit and machine rigidity

Verify that your spindle or tool holder accepts a 20 mm shank and that the machine provides sufficient rigidity for heavy roughing cuts. Confirm the workpiece material hardness does not exceed HRC45 and that your coolant or lubrication setup suits aluminium, steel, stainless steel or copper machining.

Questions about this item

How often will the AlTiN coating on this 4-flute roughing end mill need replacement when cutting HRC45 steel?

The AlTiN coating on this solid carbide end mill wears gradually; expect to replace the tool once the coating no longer protects the cutting edges during HRC45 steel roughing.

What limits continuous cutting time with this 100 mm overall length roughing end mill?

Chip evacuation in deep slots becomes the first limit during sustained use, as the 4-flute design packs chips faster than coolant can clear them.

How much heat does this AlTiN coated carbide cutter generate during all-day roughing in stainless steel?

The AlTiN coating reduces friction, but continuous roughing in stainless steel still produces high cutting-zone temperatures that require flood coolant to manage.
