If you need a tough little cutter for stonework, the DeWalt DW47402G 110mm Marble Diamond Cutting Blade is a serious contender — it’s built to slice cleanly through marble and other dense materials without that annoying chipping that ruins edges. This 110 mm diameter blade fits most compact angle grinders and handheld cutters, so you don’t need a big saw just to get a smooth cut on a tile or slab.

The thing is, this isn’t some flimsy disc — the diamond-grit segmented blade pairs diamond abrasive with steel core strength to give you decent edge life and controlled cutting action on masonry, stone and tile work. You’ll feel the difference the first time you’re cutting through tough material and the blade stays in it instead of burning or hopping.

Key Features:

• 110 mm Diameter - Fits compact angle grinders and hand cutters common on job sites.
• Diamond Cutting Edge - Diamond grit bites into marble and stone, making cuts faster and cleaner.
• Segmented Design - Improves debris clearance and reduces heat build‑up during heavy cutting.
• Reinforced Steel Core - Keeps the blade stable under load so you’re not fighting wobble.
• Chip‑Free Finish - Made to cut without fracturing the edge of tiles and slabs.

Applications

This blade is all about tackling hard materials — marble cutting, stone, granite, engineered stone, ceramic and similar surfaces are where it shines. Stick this on an angle grinder and you can cut tiles to size, trim stone edges, make relief cuts or even fit stone around window reveals without sketchy edges.

Why Choose This Model

The bottom line is simple: you want something that gets the job done with less fuss. The DW47402G doesn’t spin out of control, it doesn’t burn through steel in a couple of cuts, and it won’t throw chips all over your floor — that matters a lot on tight jobs where finish quality counts. And because it’s a DeWalt, you know you’re getting a blade built to hold up to the sort of abuse pros put tools through day in and day out.

Technical Specifications Explained

• Blade Diameter – 110 mm - Small enough for compact tools but big enough to make smooth cuts in stone.
• Segment Height – ~10 mm - More abrasive surface to carry you through cuts before slowing down.
• No Load Speed – ~13 800 rpm - Matches well with typical grinder speeds so you’re cutting at optimum pace.
• Diamond Grit Edge - Hardwearing grit that keeps the blade effective on abrasive materials.
• Reinforced Steel Core - Stops the blade flexing under load, giving cleaner, straighter cuts.

Who Should Buy This

If you’re a stone mason, tile setter, tiler, renovator or serious DIYer needing diamond marble cutting precision, this one’s right up your alley. It’s not a toy — it’s designed for people who spend their days cutting hard materials and don’t want to fuss with blades that dull by lunch.

Sure, hobbyists can use it too — but where this blade really pays off is in repetitive, heavy cutting where a cheap blade would quickly bog down or burn edges. In practice, that’s everything from reshaping marble slabs to trim cuts on engineered stone tiling.
