1. Rau kev kos cov hlau mos (xws li kub thiab nyiaj), steel tuag txaus. Cov hlau tuag tuaj yeem muaj ntau qhov ntawm qhov sib txawv.
2. Carbide Dies - Carbide dies (Tungsten carbide nib) feem ntau yog siv los kos cov hlau hlau. Cov qauv ntawm qhov tuag no yog cylindrical (los yog me ntsis tapered) carbide core nruj nreem haum rau hauv rooj plaub hlau. Lub puab qhov ntawm lub hauv paus muaj ib lub tswb vojvoog, ib tug nkag cone, ib tug mus kom ze lub kaum sab xis, ib tug bearing, thiab ib tug rov qab nyem.
3. Hlau Hlau Tuag - Rau kev kos duab uas tsis yog{1}} ferrous hlau xws li tooj liab thiab txhuas, cov tuag zoo sib xws feem ntau siv, txawm hais tias lub puab qhov sib txawv me ntsis.
4. Polycrystalline Dies - Polycrystalline tuag (synthetic diamonds) tuaj yeem siv los kos cov xov hlau zoo. Tseem muaj cov tuag uas siv tej pob zeb diamond.
