Zvidimbu zveScrew Machine Drill Bits zvine hurefu hupfupi kuti zviome uye zvive nyore kubhoorwa. Zvinokurudzirwa pakubhoorwa kwesimbi, simbi isingasvibi, marori nedzimba dzinofambiswa.
Chibooreso chemuchina wescrew chinonzi "stub drill". Simbi inorema inomhanya. Yakagadziriswa oxide nhema, ine nzvimbo yakapatsanurwa yemadhigirii 135. Flute pfupi nehurefu hwayo zvinowedzera kuomarara kwayo, zvichikonzera kurongeka kwemaburi uye kugara kwenguva refu kwemidziyo.
Flute pfupi nehurefu hwese zvinowedzera kuomarara, zvichiita kuti maburi acho anyatsojeka uye kuti chishandiso chigare kwenguva refu.
Simbi yepamusoro ye cobalt inokurumidza zvikuru inodzivirira kupisa zvakanyanya uye inogara kwenguva refu.
Kuboora kwakarurama nekuda kwe135 Degree Split Point
Inokurudzirwa pakuboora zvinhu zvine simba rakanyanya senge simbi isina ngura, titanium, simbi yemanganese, ndiro yezvombo uye iconel.
Zvakanakira
★Kureba Kushoma, Kwakaomarara
Madhiri emuchina wescrew (anozivikanwawo se stub kana stubby drills) ane chivakwa chipfupi, chakasimba chinoshanda zvakanaka mumhando dzakasiyana-siyana dzezvinhu mumhuri dzesimbi nesimbi.

★Mabhora Anoshanda Zvakasiyana-siyana Uye Akasimba
Madhiri emuchina wescrew akafanana nesimbi inomhanya zvakanyanya, asi ane cobalt yakawanda kuti iite basa rakanaka pakucheka simbi dzakaoma dzakadai sesimbi isina ngura kana nickel alloys.
Dzinogadzirwa zvichienderana neAerospace Standard 907 dzine 135 degrees split point dzinozvitarisa dzoga uye dzinoderedza kusundidzira. Saizi diki pane 1/16 uye hombe pane 1/2 dzine 118 degrees standard point.
★Huremu Hwakakura Hwakapatsanurwa Pfungwa Tip
MaDrill America Screw Machine Drills ane nzvimbo inorema yekuparadzanisa madhigirii 135 yekuzviisa pakati uye kuderedza kusunda. Saizi diki pane 1/16 uye hombe pane 1/2 dzine nzvimbo yakajairwa ye118 degrees.
