If you cut stone for a living, you already know cheap discs don’t last. The DeWalt DW47401M 100mm Marble Cutting Blade is built as a proper diamond edge marble blade, meant for clean slicing rather than rough demolition. It’s the kind of wheel you mount on a 4-inch grinder when the finish actually matters — kitchen tops, tile work, or polished marble sheets where chipped edges will cost you time fixing them later.

Here’s the thing — a blade like this earns its keep through consistency. The 100mm compact diameter keeps handling easy on handheld grinders, and the thin cutting profile helps it move through marble without forcing the tool or overheating the stone. In practice, that means straighter lines, less vibration, and fewer ruined pieces when you're doing precision layout cuts.

Key Features:

• Diamond Cutting Rim - Provides smoother marble cuts with less edge chipping.
• 4-Inch / 100mm Size - Fits standard small angle grinders used on most tile and stone jobs.
• Thin Kerf Design - Reduces drag so the grinder works easier and cuts faster.
• Stone-Focused Bond - Designed specifically for marble and similar soft stone materials.
• Dry or Light Wet Cutting Capability - Gives flexibility depending on job site setup and dust control.

Applications

This blade shines in marble slab trimming, tile installation work, vanity fitting, flooring adjustments, and detail cuts where a bulky segmented concrete wheel would just wreck the finish. And that matters a lot on a job site — because once polished stone chips, you’re either hiding it with trim or replacing the piece. It’s also handy for softer natural stones and decorative panels where controlled cutting beats brute force every time.

Why Choose This Model

What really stands out is the balance between price and dependable site performance. The DeWalt stone-grade diamond mix holds its edge longer than bargain discs, while the stable steel core keeps wobble down when you're running a handheld grinder at full RPM. But the real win? Predictable cutting. No sudden grabbing, no wandering off your line — just steady, controllable progress that lets you work faster without babysitting the blade.

It’s especially useful for tradespeople who rely on a compact angle grinder daily and need a dependable marble disc that cuts clean without costing premium-brand money.

The bottom line is simple. If your work involves decorative stone where clean edges matter and rework costs time, the DW47401M marble cutting blade is a solid everyday choice. Not flashy. Not gimmicky. Just a straightforward site tool that does exactly what you expect when the grinder spins up.
