| 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. Limited by spindle power, not tool endurance |
| 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 |
19m/min (3000rpm) |
1mm | 0.5mm |
0.02 (120mm/min) |
Works OK, 150mm/min is too much |

9m/min (3000rpm) |
1.2 mm | 0.95mm |
0.0022 (20mm/min) |
Too much WOC, breaks cutters |
| 2mm 4-flute flat end mill | HSS | Uncoated |
19m/min (3000rpm) |
3 mm | 0.8mm |
0.01 (120mm/min) |
Nice surface finish, might be able to go a little faster but was making noise |
| 60 degree 0.3mm tip engraver 1/8" shank | solid carbide | TiAlN coated |
25m/min (calculated) (2500rpm) |
N/A | 0.6mm |
0.02 (50mm/min) |
Cutter sometimes breaks, probably should try higher rpm |
| 90 degree 0.3mm tip engraver 1/8" shank | solid carbide | TiAlN coated |
30m/min (calculated) (3000rpm) |
0.25 | 0.5mm |
0.01 (30mm/min) |
Seems to work, could maybe do deeper or faster? |

| 6mm 2-flute jobber drill | HSS | TiN |
14m/min (730rpm) |

Was in danger of stalling spindle, definitely the maximum size that can be drilled in this material |
