5 SL-TAFLET Technical Features thread forming and removing the seams typical for thread forming. reamer cuts the crests of the formed thread thus partially or fully removing the two seams created during the torque is reduced by approximately 20%. Conventional forming tap 1.1 Conventional forming tap Advantages in Production crest is created. diameter of the side reamer. This process also achieves improved concentricity of the hole and the thread. cannot remain between the seams thus avoiding rust or other problems. thread making it safe for applications in the hydraulic or medical fields. 1.2 SL-TAFLET 2.1 SL-TAFLET SL-Taps are patented: Japan patent no US patent no Europa patent no

6 SL-TAFLET Application of thread engagement is reached. This ensures full removal of the thread seams by the side reamer. Please refer to the table 3.1 to choose the appropriate drill hole diameter. seams may remain on the threads crest because they are lower than the internal diameter of the required thread. However, choosing low thread engagements reduces tapping torque and increases tool life. compacted threads making the produced thread stronger.

Reaming the minor diameter of the thread to the required one. side reamer (Picture 2.1). In through holes with thin film bottoms, these bottoms are removed by LT taps creating a clean, burr-less exit of the hole. cooling Side reamer LT-Taps are patented: Japan patent no US patent no Europa patent no illing face Internal Coolant Hole illing face Side Reamer Internal Coolant Hole illing face Side Reamer Through Hole

13 LT ULTI-FUNCTION-TAP Advantages in Production This reduces production time, tool cost and reduces overall production cost. process and avoids problems with cast surfaces since these are completely removed. molded holes are corrected in the process. guarantees perfect concentricity of the hole and the thread. Application - The diameter of the hole at the entry should be according to the normal drill diameter for cutting taps. This is approximately the nominal diameter minus the pitch. For a tap 6 the - The minimum diameter of the hole should be 0.6 x the nominal diameter of the thread. For a tap 6 it should therefore be 0.6 x 6 mm = 3.6 mm. - From these two values the incline of the molded hole may be calculated as shown in the picture below.
