All recipes from personal experience and tested

Key

Colour	Meaning
Blue	Not (proven) a maximum, could do more
Green	A demonstrated maximum, any more will break tools
Red	Known to be excessive, will break tools

Aluminium

Roughing

Tool Size/type	Material	Coating	Surface speed (RPM)	DOC	WOC	FTP (feed rate)	Comment
12mm 4-flute flat end mill	HSS	Uncoated	100m/min	10mm	4mm	0.03 (250mm/min)	Noisy and spindle only just copes, definitely a maximum, use conventional milling only
5mm 4-flute flat end mill	HSS	Uncoated	40m/min (2500rpm)	5mm	1.5mm	0.02 (200mm/min)	Good finish, not a maximum could have done more
2mm 2-flute ball nose end mill	HSS	TiAlN coated	15m/min (2500rpm)	0.5mm	0.5mm	0.015 (150mm/min)	Too much, breaks cutters

H-13 Tool Steel

Roughing

Tool Size/type	Material	Coating	Surface speed (RPM)	DOC	WOC	FTP (feed rate)	Comment
6mm 4-flute flat end mill	solid carbide	TiAlN coated	35m/min	7mm	0.5mm	0.04mm	Width is at maximum, depth might be deeper
