If you've ever spent extra time grinding and polishing porcelain tile edges after a miter cut, you know how much it slows down a job. The DISTAR Galaxy 5" Diamond Blade was engineered to eliminate that step entirely—delivering a cut-and-finish result in a single pass.
The Problem with Traditional Miter Cutting
Standard diamond blades cut fast, but they leave rough, chipped edges on porcelain tile. That means after every 45° bevel cut, you're reaching for a polishing pad or angle grinder to clean up the edge before it's installation-ready. On large-format tile projects, that extra step adds up fast—in time, labor, and cost. For a full breakdown of why 45° cuts are more demanding, see Cutting Tiles at a 45° Angle – How to Achieve a Clean Edge Without Chipping.
Twin-Win Technology: Cut + Finish in One Pass
The Galaxy blade features a dual-sided diamond layer design that does two jobs simultaneously:
- Turbo cutting side (coarse diamonds): Fast, aggressive cutting with active cooling
- Smooth finishing side (fine diamonds + soft bond): Refines the visible edge during the cut
The result? Clean, chip-free edges straight off the cut—no secondary polishing required in most cases. When a mirror finish is needed, follow up with the Proxxon WP/A and Distar CoolPAD polishing pads. See the full guide: How to Polish Porcelain Tile Edges with the Proxxon WP/A + Distar CoolPAD.
Where It Shines
The Galaxy blade is purpose-built for 45° bevel (miter) cuts on porcelain tile and porcelain gres, seamless edge joints for modern frameless installations, and high-visibility edges in kitchens, bathrooms, and large-format tile projects.
