Often the thread is standard but the catalogue tap is not right: it needs to be longer, coolant-through, oversize, a special tolerance class, suited to a difficult material — or the inch or pipe size simply is not available.
We modify spiral-point taps (through holes, chips pushed ahead), spiral-flute taps (blind holes, chips pulled out), straight-flute taps and pipe taps (G, R/Rc, NPT) to your application.
Typical applications: machine shops, automotive parts, valves and fittings, hydraulics and pneumatics, tool distributors

Questions
Spiral-point or spiral-flute tap — which one do I need?
Use a spiral-point tap for through holes: it pushes chips ahead and out of the hole. Use a spiral-flute tap for blind holes: chips travel up the helix and out. Very soft or gummy materials also need an adjusted helix and rake angle — just tell us the workpiece material.
