Bottom Taps

Bottom Taps — New & Used

Bottoming taps (bottom taps) feature a very short chamfer (typically 1–2 threads) to cut usable threads near the bottom of blind holes. They’re ideal for maximizing thread depth after a taper or plug tap, or for CNC rigid tapping where minimal lead is required. Available in HSS, cobalt, and carbide with coatings like TiN, TiCN, and TiAlN, bottom taps produce clean, accurate threads in steel, stainless, aluminum, and non-ferrous alloys across UNC, UNF, and metric series.
