Tru-Flo® Thread Forming Taps

Tru-Flo® Thread Forming Taps

Thread forming taps (Tru-Flo taps) offer improved thread quality and strength due to the fluteless design, and therefore allows for greater fastener strength in the threaded product. This tap does not cut, so it is “chipless,” and therefore will not cause a chip problem.  This is why thread forming, over thread cutting, eliminates costly and time-consuming chip clean-up and disposal.

Tapping speeds can be increased as much as double that of conventional cutting taps...more tapped holes per hour.  North American Tool popular special Tru-Flo sizes are shipped in 24-Hours.

Tips for using thread forming taps:

  • Tru-Flo taps operate most efficiently at spindle speeds 1-1/2 to 2 times faster than those recommended for conventional cutting taps, especially in softer materials and/or with fine pitch Tru-Flo taps. 
  • As higher speeds are attained, adequate lubrication is essential for prolonged tap life and thread quality.
  • When using Form Taps, the pitch diameter limits recommended to produce different classes of thread differ from those recommended for conventional taps.
  • Since it is more important to “lubricate” the cold forming tap that to “cool” the tap, Tru-Flo taps should be used with conventional lubricating cutting oils or EP (extreme pressure) rated oil.  Soluble oils or similar coolants are not recommended.
