Igiya le-Worm liyisondo elinezinhlungu elinezimpethu, liguqula ukunyakaza kwe-rotary kwesibungu kube ukunyakaza okuqondile kwegiya. Amazinyo egiya lezibungu agawulwa engela elifana ne-angle ye-helical groove kwisibungu.

Emshini wokugaya, igiya le-Worm kanye ne-Worm lisetshenziselwa ukulawula ukuhamba kwekhanda noma itafula. Isibungu ngokuvamile siqhutshwa yimoto, futhi njengoba ijikeleza, ifaka amazinyo egiya lezibungu, okwenza amagiya ahambe. Le nhlangano ivame ukucaciswa kakhulu, ivumela ukuma okunembile kwekhanda noma itafula.

Inzuzo eyodwa yokusebenzisa igiya le-Worm kanye ne-Worm emishini yokugaya ukuthi ihlinzeka ngezinga eliphakeme lenzuzo emishini, elivumela imoto encane kakhulu ukushayela isibungu ngenkathi kufinyelela ukunyakaza okuqondile. Ngaphezu kwalokho, ngoba amazinyo egiya lezibungu ahlanganyela nesibungu endaweni engajulile, kunokuxabana okuncane nokugqoka kwizakhi, okuholela empilweni yenkonzo ende yohlelo.
