{"product_id":"weha-blitz-cluster-cup-wheel","title":"Weha Blitz Cluster Cup Wheel — 4\" \u0026 5\" | 50\/60 Grit | Fast Stock Removal for Granite, Marble \u0026 Engineered Stone","description":"\u003cp\u003eThe Weha Blitz Cluster Cup Wheel is built for aggressive stock removal where speed matters. The cluster segment design — raised diamond clusters separated by open gullets — cuts faster than solid-face cup wheels by maximizing diamond exposure and clearing debris efficiently. Available in 4\" and 5\" diameters at 50\/60 grit, the Blitz handles the heavy work: fiberglass mesh removal, epoxy and resin removal, backing removal, edge shaping, and surface preparation on granite, marble, quartz, and engineered stone. Runs wet or dry.\u003c\/p\u003e\n\n\u003ch2\u003eWhat the Cluster Design Does\u003c\/h2\u003e\n\u003cp\u003eStandard cup wheels grind with a continuous diamond face. The Blitz uses raised cluster segments with open channels between them — this exposes more diamond per pass, reduces heat buildup, and clears slurry faster. The result is more aggressive material removal with less wheel loading and longer tool life compared to solid-face alternatives.\u003c\/p\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFiberglass mesh and backing removal\u003c\/li\u003e\n\u003cli\u003eEpoxy and resin removal from stone surfaces\u003c\/li\u003e\n\u003cli\u003eFast edge shaping and stock removal\u003c\/li\u003e\n\u003cli\u003eSurface preparation before polishing\u003c\/li\u003e\n\u003cli\u003eGrinding down high spots and seams\u003c\/li\u003e\n\u003cli\u003eWet or dry use on granite, marble, quartz \u0026amp; engineered stone\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGrit: 50\/60\u003c\/li\u003e\n\u003cli\u003eSizes: 4\" (SKU 50230) and 5\" (SKU 50231)\u003c\/li\u003e\n\u003cli\u003eThread: 5\/8\"-11\u003c\/li\u003e\n\u003cli\u003eUse: Wet or dry\u003c\/li\u003e\n\u003cli\u003eDesign: Cluster segment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWorks Well With\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/weha-pitbull-hybrid-resin-diamond-cup-wheel\"\u003eWeha Pitbull Hybrid Resin Cup Wheel — Follow-up shaping after Blitz stock removal\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/weha-4-resin-filled-diamond-cup-wheel\"\u003eWeha 4\" Resin Filled Diamond Cup Wheel — Smoothing after aggressive grinding\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/weha-4-flap-diamond-cup-wheel\"\u003eWeha 4\" Flap Diamond Cup Wheel — Controlled shaping and polish removal\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/weha-vacuum-brazed-zero-tolerance-wheel-no-bearing\"\u003eWeha Vacuum Brazed Zero Tolerance Wheel — Precision profile and edge shaping\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/weha-trilogy-3-step-polishing-pads\"\u003eWeha Trilogy 3-Step Polishing Pads — Final edge polish after grinding sequence\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Weha","offers":[{"title":"4 inch","offer_id":51164329640160,"sku":"50230","price":75.92,"currency_code":"USD","in_stock":true},{"title":"5 inch","offer_id":51164329672928,"sku":"50231","price":103.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/3943\/1904\/files\/Weha_blitz-5in-cluster-50-60-grit-back.png?v=1774356492","url":"https:\/\/protoolhaus.com\/products\/weha-blitz-cluster-cup-wheel","provider":"Pro Tool Haus","version":"1.0","type":"link"}
