Sometimes finesse can wait.
You need to remove material—and you need to do it fast.
The Crowne 4.5" CGS 40/50 Grit Diamond Disc combines cutting, grinding and shaping capability into one aggressive wheel built for serious material removal.
Cut.
Bevel.
Grind.
Shape.
Round.
Flatten.
The coarse 40/50 diamond grit gives you the bite to get through the heavy work quickly before moving on to finer finishing.
Material removal.
The coarse 40/50 diamond grit is designed to remove material aggressively, making this the CGS to grab when speed and shaping power matter more than leaving behind a fine finished surface.
Use it to establish the shape.
Remove the bulk.
Then refine the surface with a finer grit when necessary.
REMOVE FIRST. REFINE SECOND.
CGS tells you exactly what this disc was built to do.
Make minor cuts, corrections and adjustments without immediately switching to a dedicated blade.
Take down high spots, remove unwanted material and clean up rough areas.
Create bevels, curves, rounds, notches and profiles with aggressive material removal.
One disc.
A whole lot of jobs.
The 40/50 CGS is ideal for:
Aggressive edge shaping
Initial beveling
Miter preparation
Rough shaping
Rounding edges
Notching
Minor cut corrections
Flattening high spots
Removing excess material
Preparing an edge for finer finishing
When you've got material standing between you and the shape you want, this is where you start.
Designed for professional work on:
Porcelain
Ceramic tile
Granite
Marble
Quartz and compatible engineered stone
Natural stone
Whether you're roughing in a profile, correcting an opening or preparing a miter, the 40/50 CGS gives you the aggressive bite to get the first stage done quickly.
We've got both because they do different jobs.
REMOVE
Coarse and aggressive.
Choose 40/50 when you need faster material removal, rough shaping and initial profiling.
REFINE
Finer and more controlled.
Choose 100/120 when you want more controlled removal and a smoother finished surface.
40/50 → REMOVE
100/120 → REFINE
Pick the disc based on where you are in the process.
The advantage of CGS isn't just aggression.
It's versatility.
Instead of constantly bouncing between a cutting blade, grinding wheel and shaping disc for every small adjustment, CGS gives you multiple capabilities in one wheel.
That's fewer accessory changes.
Less screwing around.
More time getting the tile where you need it.
