1.Kudula Kapangidwe kamtunduwu kosindikizidwa komanso kopanda kusindikizidwa ma koni atatu:
Kusalimba kwa mano kumakulitsidwa ndi premium tungsten carbide yoyang'ana pamano pazitsulo zachitsulo.
2.Gauge Kapangidwe kamtundu uwu magawo atatu a miyala ya cone:
Kutetezedwa kwa ma geji angapo okhala ndi zoyezera chidendene ndi zoyikapo zoyezera pachidendene pamwamba pa kolona, zoyikapo za tungsten carbide ndi kuyang'ana kolimba pa shirttail kumawonjezera mphamvu yogwira ndi kubereka moyo.
3.Bearing Structure yamtundu uwu atatu cone rock bits :
Wodzigudubuza wapamwamba kwambiri wokhala ndi nkhope ziwiri.Mpira loko wa cone.Thrust umayang'anizana ndi nkhope yolimba yokhala ndi aloyi osamva.Kukana kwa abrasion ndi kugwidwa kwamtundu kumawonjezeka
Table of classification of hardness and bit select
