The bottom line: this 12in, grit 80, diamond-coated flat lap disc delivers aggressive, controlled material removal on glass, stone and ceramics, and its A3 steel backing keeps the disc flat under load. For anyone needing a single-sided electroplated diamond wheel for bench lapidary or tile shaping, this disc is a practical choice rather than a precision finishing tool.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12in diameter and grit 80:\u003c\/strong\u003e Provides a large working surface with a coarse grit for fast material removal on hard surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.2mm steel thickness:\u003c\/strong\u003e The A3 steel base gives rigid support that reduces warping during heavy grinding tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectroplated diamond coating:\u003c\/strong\u003e Diamond particles are bonded on one side to deliver durable, wear-resistant performance for extended use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat lap design:\u003c\/strong\u003e Produces an even grinding surface for controlled, repeatable removal ideal for lapidary and tile work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet or dry use:\u003c\/strong\u003e Can be used with water for better results and dust control, then wiped and dried to prevent rust.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis disc is aimed at lapidary hobbyists, tile and porcelain fabricators, and anyone who needs to shape or remove material from glass, stone, jade, agate and similar hard substrates.
