Umatshini wokusika we-annular we-TCT otshintsha ngokukhawuleza onobunzulu bokusika obuyi-75mm, 100mm

Izixhobo zeringi ze-TCT (tungsten carbide tip) ezifumaneka kubunzulu obuyi-75 mm kunye ne-100 mm, zinokuguquguquka okuninzi kwaye zizenza zilungele ukusetyenziswa kweentlobo ngeentlobo zokubhola. Ezinye zeempawu eziphambili ziquka:

1. Incam yekhabhayithi yeTungsten (TCT)

2. Isiqu sokutshintsha ngokukhawuleza

3. Ubunzulu beenketho zokusika

4. Ukususwa kwezinto ngokufanelekileyo

5. Imingxunya ecocekileyo nechanekileyo

6. Usetyenziso olunemisebenzi emininzi

7. Ukuhambelana needrill zemagnethi

8. Ubunzulu bokusika nzulu
