The DeWalt D4 180mm 60 Grit Aluminium Oxide Disc is a solid choice when you need reliable abrasive performance on metal and other tough materials. This disc offers consistent cutting power with its aluminium oxide grit, built to handle demanding jobs without wearing out too quickly.

Key Features:

• 180mm diameter - gives you a good cutting surface for larger areas, speeding up your work.
• 60 grit aluminium oxide - strikes the right balance between aggressive material removal and finish control.
• Durable construction - holds up well against heat build-up for extended grinding sessions.
• Compatible with DeWalt angle grinders - engineered to fit securely and operate safely at high speeds.
• Consistent wear pattern - prevents uneven cuts and prolongs the life of the disc.

Applications

This disc is made primarily for heavy-duty metal grinding tasks, like smoothing welds, shaping steel, or deburring rough edges. The 60 grit aluminium oxide abrasive is coarse enough to handle stubborn rust or paint removal, but won't leave behind chatter marks if you keep a steady hand. It’s also great for general fabrication work where speed and control matter equally.

Why Choose This Model

The bottom line is this disc doesn’t mess around—you get a dependable abrasive that sticks around longer than your average off-brand discs. Plus, being part of DeWalt’s lineup means it meets higher durability standards and safety ratings. What really stands out is how well it balances sharp cutting ability with resistance against glazing over, which can slow your progress fast on less capable discs.

Technical Specifications Explained

• Diameter: 180mm (7 inches) – large enough to cover more surface area per pass but still manageable on most angle grinders.
• Abrasive grit: 60 aluminium oxide – medium coarse grit that cuts through metal efficiently without sacrificing too much finish quality.
• Bore size: standard fitment (22.23mm) – fits most commercial angle grinders without adapters.
• Max RPM rating: typically around 8,600 RPM – safe use within this range ensures longevity and prevents disc failure during operation.
• Cup thickness: balanced thickness for durability and flexibility – thick enough to last through tough jobs but flexible enough to contour slightly during use.

Who Should Buy This

If you’re a pro or serious DIYer working regularly with steel or other metals, this disc gives that no-nonsense performance you need without constantly swapping abrasive discs mid-job.
