The diamond set design ensures sufficient overlap to prevent premature wear of the matrix.Surface-Set diamond bits are primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. They are also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.Size Available:Wireline Series: A,B,N,H,P(Front end & Back end Type)T Series: T36,T46,T56,T66,T76,T86WF Series: HWF,PWF,SWF,UWF,ZWFWT Series: RWT,EWT,AWT,BWT,NWT,HWT(Single Tube/Double Tube)WG Series: EWG,AWG,BWG,NWG,HWG(Single Tube/Double Tube)WM Series: EWM,AWM,BWM,NWMT2/T6 Series: T256,T266,T276,T286,T2101/T676,T686,T6101,T6116,T6131,T6146,T6HOthers: NMLC,HMLC,LTK48,LTK60,TBW,TNW,ATW,BTW,NTW,AQTKNXD3,NXC,T6H,SK6L146,TT46,TB56,TS116,CHD101All Chinese Sizes.
