Advantage
Durable Material: Made of good-quality alloy with a diamond-plated surface (double-coated for adhesion), rust-resistant, corrosion-resistant, ensuring long service life and resistance to wear.  The brass core minimizes shaft binding, preventing sticking to the grinder. Chrome-plated and hardened for enhanced strength and durability.  
Efficient Tools: The ceramic-stained glass abrasive tool provides faster cutting, prevents sliding, and increases wear resistance. The inner coating ensures outstanding durability and sharpness, reducing friction and running cooler, fit for most glass grinding machines, suitable for handmade enthusiasts, designers, and artisans.

Instruction
 Ensure the grinder shaft diameter is smaller than 8mm before use. And always use water or coolant during operation to prevent overheating and extend bit life. Adjust the bit’s position up/down periodically to distribute wear evenly. Clean bits after use to remove debris and maintain efficiency.  

Note
Please wear protective gear (gloves, goggles) and avoid dry grinding to prevent damage.  Make sure the size is suitable for your needs before purchasing.
