The DEWALT DW4738 4-3/8-inch Tile Blade is a wet/dry cutting accessory built for tradesmen and serious DIYers who need long blade life and clean edges. Its premium XP4 diamond cutting matrix delivers up to four times the life of standard blades, while the continuous rim helps prevent chipping in ceramic, porcelain, and other tile.
Chipping is one of the most frustrating issues when cutting tile. The DW4738's continuous rim design is engineered to produce chip-free cuts in a variety of tile materials. For best results, use a steady feed rate, keep water flowing in wet cutting situations, and let the blade do the work—forcing it can cause breakout.
DEWALT's XP4 matrix provides four times the life of standard blade designs. You'll spend less time swapping blades and more time cutting, especially on large flooring or wall projects.
This 4-3/8-inch blade is designed for high-power tile saws, allowing quick, free, low-heat, straight cuts. Laser-cut expansion slots (featured across the XP line) reduce heat buildup and minimize blade warping, which helps keep cuts straight.
Whether you're using a wet saw on porcelain or a dry saw on ceramic, the DW4738 is built to handle both. Always check your saw's arbor size and RPM rating, and use the appropriate water flow or dust extraction for dry cutting.

The continuous rim on the DW4738 is your first defense against unsightly chipped edges. But technique matters just as much. Score the tile face with a straightedge guide, maintain a steady push, and avoid twisting the blade.
Wet cutting keeps the blade cool and controls dust, but dry cutting can be acceptable for short runs if you let the blade spin freely. Match the cutting method to your saw's capabilities and the tile material.
For standard ceramic tile up to 4-3/8 inches, this XP4 blade is a reliable choice. On large-format porcelain or stone, verify that your saw's RPM and arbor are compatible. A true, sharp blade gives cleaner cuts and reduces breakage.
Chipping is often caused by feeding the blade too quickly, using a worn blade, or insufficient water flow. Use a consistent, moderate feed speed, keep the blade wet (when wet cutting), and make sure the blade is properly mounted and true.
Yes, the DW4738 is designed for cutting a variety of tiles, including porcelain. For best results with hard porcelain, use wet cutting and a stable work surface.
The blade has a 7/8-inch arbor, which is common on many tile saws and angle grinders. Check your tool's spindle size and speed rating to confirm compatibility before use.
The XP4 matrix is rated for up to 4x the life of standard blades. Actual lifespan depends on tile hardness, cutting technique, and whether you use wet or dry cutting.
Yes, the DW4738 is rated wet/dry. For dry cutting, let the blade cool periodically and use proper dust control.
Cuts tile clean.
This blade is smooth. No chipping on porcelain. Great for the price.
I'm a tile setter and this blade has been a workhorse. It cuts through ceramic and porcelain with ease. The continuous rim ensures a chip-free edge. It lasts much longer than the cheap blades. I've used it wet and dry, it works both ways. The arbor fits my saw perfectly. I'd recommend it to any tradesman.
Good blade, but it wears out fast on natural stone. For regular tile, it's great.
I did a full bathroom remodel and this blade didn't disappoint. I used it to cut large format porcelain. The cuts were precise and didn't chip. The diamond matrix seems to be high quality. It didn't need frequent dressing. The only issue is it's a bit expensive. But you get what you pay for.
Does its thing.
I've only used it once, but it was smooth. The cut edges are clean. I'm satisfied.
