1. Raws li cov binder, muaj peb pawg: resin, hlau thiab ceramic daim ntawv cog lus, cov cuab yeej pob zeb diamond. Cov txheej txheem hlau hlau tau muab faib ua ntau pawg, xws li sintering, electroplating, thiab brazing.
2. Raws li cov qauv siv, nws muab faib ua:
Abrasives - sib tsoo log, rollers, rollers, edging log, sib tsoo discs, tais grinders, mos sib tsoo discs, thiab lwm yam.;
Cov cuab yeej sawing - ncig saws, kab saws, hlau saws, raj saws, band saws, saw saws, hlau saws;
Drilling cuab yeej - geometallurgical khoom, roj (gas) zoo khoom, engineering nyias-walled khoom, pob zeb khoom, iav khoom, thiab lwm yam.;
Lwm cov cuab yeej - cov cuab yeej hnav khaub ncaws, riam, kos duab tuag, thiab lwm yam.
Piv nrog rau cov hlau daim ntawv cog lus carcass, cov resin thiab ceramic binder carcass muaj lub zog tsawg, uas tsis haum rau sawing, drilling, thiab hnav cov cuab yeej, thiab feem ntau tsuas yog cov khoom abrasive.
