Mapombi eSpiral point anonziwo matip taps. Akakodzera maburi anopinda nepakati neshinda dzakadzika. Ane simba guru, anogara kwenguva refu, anokurumidza kuchekwa, saizi dzakagadzikana, uye mazino akajeka (kunyanya mazino akanaka). Imhando yekuchinja kwemapombi akatwasuka. Akagadzirwa muna 1923 naErnst Reime, muvambi wekambani yeGerman NORIS. Kune rimwe divi regomba rakatwasuka, mupendero wekucheka unogocherwa kuti ugadzire kona, uye machipisi anoburitswa mberi achitevedza nzira yebanga. Akakodzera kugadziriswa nepakati nepakati.
Hunhu hwayo ndehwekuti goko rakaita sewedge rinovhurwa pamusoro pepombi yegorova yakatwasuka kuti ichinje chimiro chekoni yekucheka, nokudaro zvichisundira machipisi mberi uye zvichiriburitsa. Saka, rinowanzo shandiswa chete pakubaya shinda nepaburi.
Nekuti nzira yakakosha yekubvisa chips dze screw-point taps inodzivirira kupindira kwemachips pamusoro pe thread yakagadzirwa, mhando ye thread ye screw-point taps inowanzo kuve nani pane ye spiral flute taps nema straight flute taps.

Pamusoro pezvo, matepi ane screw-point anowanzova nemipendero yekucheka 4-5, izvo zvinoderedza huwandu hwekucheka pazino rega rega, nokudaro zvichiwedzera hupenyu hwepombi. Kazhinji, zvichienzaniswa nematepi ane spiral fluted, hupenyu hwematepi ane screw-point huchawedzerwa kanenge kamwe chete.
