Description

The DEWALT DWA47421 14-inch segmented diamond circular saw blade is built for tough masonry cuts on bench-top and stationary saws. Its extended-performance diamond matrix and large diamond segments with cobalt make it ideal for concrete, brick, cinder block, ceramic, stone, and similar abrasive materials. It’s designed for both wet and dry cutting, so you can match the blade to your saw and job site.

DEWALT DWA47421 14-Inch Diamond Blade: Wet or Dry Masonry Cutting

The segmented rim consists of laser-welded diamond segments attached to a heat-treated steel body. This gives the blade durability and lets it dissipate heat during long cuts. The thin kerf removes less material, so the saw works easier and you get smoother, cleaner cuts.

Compatibility and Sizing

This blade fits most masonry saws that accept a 14-inch blade with a 1-inch arbor. It’s a common size for tile saws, cut-off saws, and stationary table saws used for concrete and stone. Before buying, verify your machine’s spindle size and maximum blade diameter to ensure a safe fit.

Cutting Wet or Dry: What to Expect

Wet cutting keeps the blade cool, reduces dust, and often gives a cleaner edge. Dry cutting works when water isn’t available, but you should let the blade run free for a few seconds between passes to cool. For both methods, use a steady feed and avoid forcing the blade through the material.

Product Details

Why a Segmented Rim Works Best for Masonry

Segmented diamond blades cut aggressively by breaking the rim into open slots that cool the blade and eject debris. This makes them a solid choice for brick, block, and concrete. The DEWALT DWA47421 combines that segmented design with a cobalt-enhanced diamond matrix, so the segments stay sharp during heavy use.

Get Cleaner Cuts with a Thin Kerf

The thin kerf removes less material, which means your saw doesn’t have to work as hard. In masonry, that translates to faster cuts and less wear on the motor. It also reduces chipping along the cut line, especially on tile and ceramic.

Matching the Blade to Your Saw

Before buying a 14-inch blade, check two things: the arbor size (must be 1 inch) and the saw’s maximum blade diameter. The DWA47421 is a common upgrade for many bench-top masonry saws, and it can be switched between wet and dry operation with no modifications.

Frequently Asked Questions

Can this blade be used on a handheld angle grinder?

No, a 14-inch blade is not designed for handheld angle grinders. Use it with a stationary masonry saw or a cut-off saw that matches the 14-inch size and 1-inch arbor.

What materials can I cut with this blade?

It’s designed for brick, cinder block, ceramic, stone, concrete, and similar masonry materials. Avoid steel and other metals.

Is water required?

No, the blade can be used dry, but wet cutting is recommended for longer blade life and dust control when water is available.

What is the maximum RPM?

The blade is rated to 4,500 RPM. Never exceed the saw’s maximum speed rating.

Does this blade fit a 14-inch tile saw?

Most tile saws with a 1-inch arbor and 14-inch blade capacity will accept it. Confirm your saw’s arbor before ordering.

Cuts concrete effortlessly

This blade cuts through concrete block effortlessly. I used it wet, but it also works dry. The 1-inch arbor fit my saw without any adapters. The cut is smooth with minimal chipping. It's a bit pricey but worth it for the durability.
