The part number decodes as follows: SM = Supermill brand, 5F = 5 flutes, 250 = 0.250 in (1\/4 in) diameter, 015 = 0.015 in corner radius — indicating this is a corner-radius (bull-nose) end mill, not a fully sharp square end. The tool features a dark AlTiN (aluminum titanium nitride) PVD coating, visible as the uniform black finish on the flute section, which provides high hardness, oxidation resistance up to ~1400°F, and reduced friction, making it well-suited for machining steels, stainless steels, cast iron, and hardened alloys. The 5-flute geometry with variable helix provides increased feed rates and improved surface finish compared to 4-flute designs while reducing chatter; the extended neck geometry (3\/4 in LOC in a 2-1\/2 in OAL tool) allows for deeper axial reach in pockets and slots. Compatible with standard 1\/4 in ER collet chucks, hydraulic toolholders, and shrink-fit holders.\u003c\/p\u003e\n\u003ch3
