DEWALT DW4777T Diamond Cup Wheel Features

High diamond concentration for aggressive material removal and extended wheel life
Large grinding segments with heat-treated steel bodies for increased durability
5/8-11 arbor fits common angle grinders
12,200 RPM max speed for fast, efficient grinding
Dry grinding capability for concrete and masonry

What to Consider When Choosing a 5-Inch Diamond Cup Wheel

The 5-inch size offers a good balance of surface coverage and maneuverability for large flat areas, while the turbo rim design produces a smoother finish compared to a standard segment wheel. Match the arbor size to your grinder, and verify the RPM rating does not exceed your tool's maximum speed for safe operation.

Concrete and Masonry Grinding Applications

Use the DW4777T for dry grinding of concrete slabs, masonry blocks, and stone veneer. It excels at removing form marks, leveling high spots, and smoothing uneven surfaces. Always wear appropriate dust mask and eye protection, and use a grinder guard where required.

Product Details

Get the Most from Your DEWALT Diamond Cup Wheel

Choosing the right diamond cup wheel depends on the material and the finish you need. The XP Turbo design pairs a turbo rim with a high diamond concentration for a smooth finish and faster cutting. When grinding concrete, let the wheel do the work and keep it moving in a consistent pattern to avoid gouging. For deeper material removal, work in multiple passes.

5-Inch vs. 4-Inch Cup Wheels

A 5-inch wheel covers more surface area, making it a better choice for larger slabs and open areas. It also runs cooler due to greater segment exposure. The 4-inch wheel is more maneuverable in tight spaces and lighter on the grinder, but requires more passes to cover the same area.

Whichever size you choose, always match the arbor size to your grinder and verify the RPM rating. With proper care, a DW4777T can withstand tough daily use on the job site.

Frequently Asked Questions

Can this wheel be used on a variable speed grinder?

Yes, the DW4777T can be used on a variable speed grinder, but do not exceed the maximum rated speed of 12,200 RPM. Set the grinder to a speed within the wheel's rating for safe operation.

What is the difference between XP Turbo and standard Turbo diamond cup wheels?

XP Turbo wheels feature a higher diamond concentration and larger grinding segments, which provide faster material removal and longer life compared to standard turbo wheels. This makes them ideal for demanding concrete and masonry jobs.

Can this wheel be used for wet grinding?

The DW4777T is designed for dry grinding. For wet applications, choose a diamond cup wheel specifically rated for wet grinding to avoid damage and ensure safety.

What safety precautions should I take when using this wheel?

Always wear eye protection, a dust mask, and hearing protection. Use a grinder with a proper guard, and ensure the wheel is properly mounted and the arbor fits securely. Never exceed the maximum RPM rating.

This wheel eats concrete. I used it to level a patio. Much faster than my old wheel.
