Core Drill Bit arung arai lata ai lam

1. Steel: Madung core drill bit material gaw n-gang rai nna, n-gun kaba ai-steel hte alloy n-gang ni hpe lang ai. High-speed steel gaw, n-gun n law ai steel ni a jak rung ra kadawn ai lam ni hpe galaw lu ai, n-gun n law ai steel re. Alloy steel chyawm gaw, drill bit a prat galu ai lam, hkrak ai lam, htu ai atsam ni hta grai kaja ai rawt jat lam ni hpe jaw ya ai, raitim ndai gaw dai hte maren grau law ai galaw shapraw ai manu hte du wa ai.

2. Tungsten Carbide: Tungsten Carbide gaw grai ja ai arung arai langai rai nna, grau ja ai nlung ni hpe jak hte galaw shapraw lu ai. Steel hte shingdaw yang, tungsten carbide htu ai n-gang ni gaw grau ngang kang nna, asak galu ai. Raitim, n kaja ai lam gaw, tungsten carbide drill bits ni gaw grai hkrat sum chye ai majaw, shanhte a n-gun atsam hte ngang kang ai lam hpe matut manoi tawn da na matu, laksan nbung laru hte tsi lajang ra ai.

3. Diamond: Diamond gaw grai ja ai arung arai rai nna, n-gun ja ai arung arai amyu myu hpe galaw shapraw lu ai, dai ni gaw ceramics, glass, quartz, marble ni rai nga ai. Diamond drill bits ni gaw laklai ai hkrak ai lam, htu ai atsam, n-gun n rawng ai lam ni hpe jaw ya lu ai raitim, galaw shapraw ai manu grai law ai majaw, manu grai hpu ai.
