The single-sided diamond coating and thin 1mm profile deliver fast material removal with a surprisingly smooth finish, making it ideal for shaping and fine grinding. It is sold as a single pack in multiple grits, and the review highlights that the wheel balances cutting speed and finish quality well, though size and occasional edge damage reported by some users are worth noting.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiamond coating:\u003c\/strong\u003e Nearly 95% coverage on one side provides aggressive cutting action for faster shaping of stone and glass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThin 1mm profile:\u003c\/strong\u003e The slim thickness keeps removal precise and reduces the amount of material lost during grinding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple grit options:\u003c\/strong\u003e Available in 1500, 2000, 2500, and 3000 grits so users can progress from rapid shaping to fine polishing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh operating speed:\u003c\/strong\u003e Rated to 30000rpm so it fits with common gem faceting machines and small lathes without speed compromises.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRubber bond finish:\u003c\/strong\u003e The embedded abrasive with rubber bond helps deliver a smoother surface than rigid metal-backed alternatives.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis disc is best for lapidary hobbyists, gem faceters, and small workshops that cut or sand stones and glass and need a compact disc that moves material quickly while still allowing fine finishing.
