QEP Black Widow 10-Inch Diamond Tile Blade – Wet Cutting for Porcelain, Ceramic, Granite & Marble

Overview

The QEP Black Widow Diamond Blade combines premium materials with precision engineering to help you tackle hard tile materials with confidence. This wet-cutting blade targets porcelain, ceramic, granite, and marble with minimal wobble and a cleaner edge, thanks to its diamond-coated perimeter and segmented design that stays cooler during cuts.

Key features

• Porcelain-certified diamond blade cuts porcelain, marble, granite and ceramic tile
• 7 mm diamond-coated high-rim for less chipping and a cleaner cut
• 5/8 in arbor fits most brands of wet tile saws
• 6,115 max RPM for smooth, fast cutting
• Micro segments help cool the blade and prevent wobbling and chipping
• Ideal for high-speed cutting of hard masonry tile

What to expect in performance

With an emphasis on heat management and edge quality, the blade maintains stable performance even through dense materials. Independent lab tests indicate Black Widow blades offer strong durability relative to several competing blades, providing a longer potential blade life in demanding tasks.

Use cases

Perfect for bathroom remodels, kitchen backsplashes, and outdoor tile projects where porcelain, ceramic, granite or marble tiles are specified. The design supports clean, straight cuts along long runs and near edges where chip resistance matters.

• Porcelain and ceramic tile installations requiring precise, clean edges
• Marble and granite surfaces where speed matters without sacrificing edge quality
• Wet-cutting tasks where heat buildup could affect cut quality

Installation and care

Use with a compatible wet tile saw and maintain proper water flow to maximize cooling. Verify arbor compatibility, avoid cross-threading, and follow RPM recommendations to protect the blade and your saw.
