Overview

The FOCSTOL Mini Diamond Disc is a compact cutting solution designed for precise work on glass, jade, crystal, tile, marble, and soft artificial stone. In a handy 50mm format, these blades deliver clean, controlled cuts with minimal edge chipping, making them a reliable choice for both DIY projects and professional setups.

Why this blade stands out

The package balances performance and value by including multiple blades plus essential mounting hardware.

Key specs include a 50mm diameter, 10mm diamond height, 1mm thickness, and diamond grit rated #100/120. These features contribute to steady cutting action across compatible materials, helping you achieve neat edges with less effort.
