| 16 | Taper taps for pipe threads made of hard material | US09367005 | 1999-08-04 | US06213693B1 | 2001-04-10 | Kazumi Kato |
| A high durability taper tap for pipe threads which can cut threads in a pipe made of hard materials having hardness of approximately 50 HRC. The sum &Sgr;&ggr; of the width angle of cutters is large, approximately 130°, thereby achieving high strength and rigidity are achieved. Since rake angle of the cutting edge &agr; is approximately −20°, cutter angle &bgr; defined by the rake face and the peripheral relief becomes more than 90° so that the strength and rigidity of a cutting edge are enhanced. In addition, since a taper of the bottom of flutes is in a ratio of 1/16, approximately equal to that of the thread portion, the rake angle &agr; of all of the cutting edges 6 is uniform so that all of the cutting edges can equally cut the threads. Further, the diameter Df of the bottom of the flutes of the top end portion is approximately 60% of the smaller end of the thread portion, which is larger than that of the common tapping tool. Owing to this configuration, the taper tap for pipe threads having high strength, rigidity and hard wearing property can be achieved. | ||||||
| 17 | Threading tap | US724860 | 1985-04-19 | US4708542A | 1987-11-24 | Dino J. Emanuelli |
| An improved tap has a thread cutting portion over which there is a Titanium nitride coating. The Titanium nitride coating has a Rockwell C hardness of at least 70. The body portion of the tap underlying the Titanium nitride coating has a Rockwell C surface hardness of at least 65. This enables the body portion of the tap to provide a rigid support for the Titanium nitride coating. Due to the interaction between the Titanium nitride coating, the relatively hard body portion of the tap, the number of flutes and the cutting face hook angle, the number of holes which can be tapped with a straight fluted tap is increased from 114 to 1,461. On a spiral pointed type tap having a relatively hard body portion interacting with the Titanium nitride, number of flutes and cutting face hook angle, the number of holes increases from 1,662 to 4,758. | ||||||
