Spiral flute machine tap / steel / for steel

Heli-Coil STI (Screw Thread Insert) taps are used for general and machine operations. The standard STI tap can be used as a basic tool to create threads ideal for threaded inserts. It is recommended that these taps are used with a CNC machine or other high-precision equipment in order to ensure a proper class of fit.

Heli-Coil offers STI taps in four styles:

Standard Plug (4-Thread Chamfer): Easy starting for through-holes and blind holes
Standard Bottoming (2-Thread Chamfer): Ideal for blind holes drilled to a minimum depth
Spiral Pointed Plug (4-Thread Chamfer): Free-cutting for use in long through-holes and in blind holes with chip clearance
Spiral Flute Bottoming (2-Thread Chamfer): Pulls chips out of deep or blind holes in soft materials (not available for metric sizes)
