The Norman – style tap is designed for blind threaded threads for long – cut materials. A fast spiral flow provides a good chip out of a blind hole. According to design and size, you can reduce up to 3 x D threads. It is not recommended to use a diameter increasing thread.
The RKB style faucet is a groove type slot for the hole application on the long cutting material.
characteristic
There is a 35-50 right-handed spiral flute
RKB has a spiral point grinding to the point where the tightly curved chip is pushed before clicking
Chamfering E(1.5-2 line)
Chamfering C(2-3 threads)
benefit
Stainless steel materials and steel alloys
In order to avoid the blockage of the chip, the wafer must be transmitted in axial direction in the blind hole application. EVA and RKB will effectively manage the chip evacuation in blind holes and holes. In addition, a profile is added to the light touch of the VA, which helps reduce friction and reduces the risk of cold welding.
Titanium wire is designed to process titanium and titanium alloys and other materials with similar mechanical properties. In these materials, the cutting edge and the thread allow the formation and shear of the chip effectively. The selection of high quality HGGH substrate and PSVD coatings provides the longest continuous use time for these difficult aviation materials.
H – Ti/plug valve
The design adopts advanced left-handed spiral groove and inverted angular geometry, optimizes the evacuation of the chip in the forward direction, increases the strength of cutting teeth, and improves the service life and technological safety of the cutter. The h-ti rake Angle remains unchanged at the full length of the slot. This means that the teeth of the high-strength materials are very stable.

Hole thread
H-ti/flat tap
Design with your right hand helix. The slow spiral groove is particularly useful in threaded holes because the diameter of the threaded hole increases (anti-hole or reaming).
