Dewalt DX3821 Laser Segmented Blades / Marble And Granite - D115XBS22.2

Ideal for marble and granite, and also suitable for other stone and masonry materials commonly encountered in construction and tiling projects.

The laser-segment geometry creates smoother, faster cuts with improved dust extraction and reduced vibration, helping you achieve cleaner finishes on hard stone surfaces and extending the blade’s life.

The blade is designed to fit 10-inch D-handle grinders, 8-inch and 10-inch Hilti grinders, and 7-inch palm and tile saws.

1) Ensure the tool is unplugged and powered off. 2) Remove the current blade and inspect the arbor. 3) Align the blade so the rotation direction mark (if present) matches the tool’s rotation. 4) Securely tighten the nut or flange according to the tool’s manual. 5) Verify the blade spins true with no wobble before making a cut. 6) Use proper PPE and connect dust extraction if available. 7) Start with a shallow cut to check alignment and performance.

Wear eye protection, hearing protection, and a dust mask or respirator. Ensure proper clamping of workpieces, maintain a steady feed rate to avoid kickback, and use dust extraction to minimize airborne particles. Keep hands away from the cutting area and inspect the blade for any damage before use.

The blade’s carbide grade and laser-segment design contribute to durability. Keep the blade clean and dry when not in use (anti-rust treated). Use appropriate cutting speeds and avoid forcing the blade through material. Regularly inspect for wear and replace if segments are damaged or worn.
