Machining Speeds Feeds: tapping
Machining speeds and feeds reference data — cutting speed (SFM), feed rate (IPR/IPT), depth of cut, tool life, surface finish, and specific cutting energy for 9 operations (turning roughing/finishing, milling face/end/slot, drilling, reaming, tapping, boring) across 14 workpiece materials (low/medium/high carbon steel, alloy steel, stainless 304/316, gray and ductile cast iron, aluminum 6061/7075, brass, copper, titanium Ti-6Al-4V, Inconel 718, plastics) and 6 tool types (HSS, uncoated carbide, coated carbide TiAlN, ceramic, CBN, PCD)
| operation | record id | cutting speed sfm max (sfm) | cutting speed sfm min (sfm) | cutting speed sfm typical (sfm) | material | material group | notes | tool type |
|---|---|---|---|---|---|---|---|---|
| tapping | Inconel_718#coated_carbide | 15 | 5 | 10 | Inconel_718 | S_superalloy | TiAlN coated; flood coolant; very low SFM; consider thread milling instead | coated_carbide_TiAlN |
| tapping | aluminum_6061#coated_carbide | 200 | 80 | 130 | aluminum_6061 | N_nonferrous | TiN coated forming tap preferred; flood or mist coolant | coated_carbide_TiAlN |
| tapping | aluminum_6061#hss | 120 | 50 | 80 | aluminum_6061 | N_nonferrous | HSS; forming tap preferred for ductile Al alloys; flood or mist | HSS |
