The Diablo DDX060DIA101F 6 in. X-LOCK Diamond Rimmed Metal Cut-Off Disc is a metal cutting accessory for angle grinders. This is a diamond rimmed metal cut-off disc designed for cutting metal with X-LOCK and 7/8 in. arbor angle grinders. Model Number: DDX060DIA101F. It is aimed at contractors, metal fabricators, maintenance crews, and serious DIY users who want longer life and more predictable performance than a standard bonded cut-off wheel.

Where this disc matters is durability. Diablo lists up to 100X longer cutting life compared to one standard bonded cut-off disc. For anyone cutting rebar, angle iron, cast iron, or steel tube, that means fewer wheel changes and less downtime. The diamond abrasive edge is applied through an advanced electro-plating process for even distribution, which is the kind of detail that helps the disc stay consistent instead of falling off fast after a few cuts.

The reinforced steel disc body is a practical advantage on the job. It helps deliver more controlled cuts and keeps the cutting diameter more consistent over the life of the disc. That matters when you want the disc to track predictably through steel instead of feeling like performance drops off every time the wheel gets smaller. Diablo also calls out less sparks and less dust, which is a real-world benefit in tighter work areas and indoor fabrication spaces.

Fitment is another strong point. This disc is designed for direct use on X-LOCK grinders with no extra parts needed, so it snaps on and releases quickly. It is also backward compatible with 7/8 in. arbor angle grinders, which makes it a flexible choice if your crew runs a mix of newer X-LOCK tools and standard grinders. You are not locked into one machine style.

At 6 inches in diameter with a maximum speed rating of 10,150 RPM, this metal cut-off disc is sized for serious grinder work while staying easy to handle. It is a good fit for cutting common ferrous stock on site or in the shop, especially when you want a longer-lasting wheel for repeat cuts rather than a disposable one-and-done accessory.

If you are the kind of user who burns through bonded wheels, this is the upgrade that makes sense. The Diablo DDX060DIA101F 6 in. X-LOCK Diamond Rimmed Metal Cut-Off Disc is best for users who value service life, fast grinder changes, and controlled metal cutting over the lowest upfront cost.
