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.
