| 2B | Ubuso bwubuso nuburinganire bwa no 2B biruta no2D.hanyuma binyuze muburyo budasanzwe bwo kuvura kugirango tunoze imiterere ya mikoranike al, No2B irashobora guhaza imikoreshereze yuzuye. |
| No.1 | Ihanaguwe n'umukandara wo gukuramo grit # 100- # 200, ufite umucyo mwiza hamwe na stari ya coarse idahagarara, ikoreshwa nkimitako yimbere ninyuma yo kubaka, ibikoresho byamashanyarazi nibikoresho byo mugikoni nibindi. |
| No.4 | Ihanaguwe n'umukandara wo gukuramo grit # 150- # 180, ufite umucyo mwiza hamwe na coarse idahagarara, ariko yoroheje kuruta No3, ikoreshwa nk'inyubako yo kogeramo imbere n'imbere imitako ibikoresho by'amashanyarazi ibikoresho byo mu gikoni nibikoresho byo gutunganya ibiryo nibindi. |
| HL | Ihanaguwe n'umukandara wo gukuramo grit # 150- # 320 kurangiza NO.4 kandi ifite imirongo ikomeza, ikoreshwa cyane nka lift yimitako yimitako, umuryango winyubako, isahani yimbere nibindi. |
| BA | Ubukonje buzengurutse, bwometse ku ruhu kandi bwambutse uruhu, ibicuruzwa bifite umucyo mwiza kandi uhinduka neza nk'indorerwamo, ibikoresho byo mu gikoni, imitako n'ibindi. |
| 8K | Igicuruzwa gifite umucyo mwiza kandi uhitamo guhinduka bishobora kuba indorerwamo. |
