The DeWalt DW47402M 110mm Segmented Marble Blade is a dedicated diamond cutting blade built to chew through stone without leaving you with a mess of chips, and that matters when you’re doing marble work where finish quality counts. This 110 mm blade is cut to fit smaller angle grinders and handheld cutters but still gives you that controlled cut you’re after on delicate stone surfaces. What really stands out is how it tackles marble – clean, flat cuts with minimal chipping – so you spend less time touching up edges and more time moving to the next cut.

In practice, the segmented diamond rim design helps clear debris fast and keeps the blade running cooler and straighter, which adds to blade life and gives you smoother passes through dense materials. And yes, that kind of performance on a small 4″ blade doesn’t just make it handy for marble – it’s a go‑to for other stone and similar masonry tasks too.

Key Features:

• 110 mm Diameter – Compact size fits 4″ grinders and lets you work marble tight spots without overkill.
• Segmented Diamond Rim – Clears dust and debris quickly so cutting stays cleaner and smoother.
• Diamond Grit Edge – Tough cutting surface that stays sharp longer than ordinary abrasives.
• Chip‑Free Cutting – Keeps edges of marble from splintering so your finish is as clean as your setup.
• Smooth Finish – Cuts with less vibration, making for straighter lines and less rework on delicate stone.

Applications

This blade shines in jobs where you’re slicing through marble slabs, stone tiles, or similar natural materials and need a chip‑free marble cutting solution without fuss — from bathroom tiling jobs to on‑site stone trimming at a renovation project.

Why Choose This Model

If you’re regularly cutting marble around a job site or shop, going with a purpose‑built segmented marble blade like this one saves time and sharpens less often than a generic multipurpose disc. It’s tuned for the material and size — you don’t have to guess how it’ll perform when you pull the trigger on your grinder.

Technical Specifications Explained

• Blade Diameter – 110 mm – Perfect for standard 4″ grinders, keeps tool balance good while still tackling solid stone.
• Bore Size – 20 mm – Standard arbor hole that fits most grinders without adapters.
• Segment Height – ~9 mm – Height of cutting segments gives a deeper diamond bite for longer life.
• Segmented Rim – Gaps between segments allow dust to escape and reduce heat buildup on long cuts.
• Material Compatibility – Made for marble and similar stone, not bare metal; keeps you from overheating and wearing it out too fast.

Who Should Buy This

If you’re a stone mason, tile installer, or even a DIYer who’s done enough marble work to care about finish, the DeWalt DW47402M marble cutting blade is a sensible pick — it doesn’t overpromise and it doesn’t underperform. It’s no fancy multi‑purpose disc, but it doesn’t need to be — it’s built for stone work and does that job straight.

And if your projects involve frequent precision cuts in marble or similar materials, grabbing a blade that’s engineered for the task is one of those decisions you’ll thank yourself for when you’re looking at those clean edges and thinking about how much time you saved on touch‑ups.
