4” Diamond Disc 180 grit

The Apex Diamond Sharpening Disc isn’t here to play — it’s built to outperform, outlast, and out-grind anything in its class. This razor-thin 1 mm diamond-coated wheel chews through tungsten with brutal efficiency, giving you a dead-sharp point in seconds.

Designed to slap onto ANY 4-1/2" angle grinder, it runs solid and controlled, no wobble, no nonsense. The 180-grit surface bites fast while still leaving a clean, precise finish that keeps your arc tight and your welds flawless.

Forget discs that glaze over or burn out — this one is engineered for punishment. Grind after grind, job after job, it stays consistent, stays sharp, and stays ready.

If you want tungsten prepped right the first time, every time, this is the disc you grab. Apex quality. Apex durability. Apex dominance.
