Engineered specifically for commercial tile setters, masonry remodeling crews, demolition specialists, and general contractors, this ultra-premium steel kit delivers an exceptional 30 percent longer service life and significantly higher material removal rates than standard entry-level chisels. Standard forged chisels quickly dull on impact, wedge themselves inside expansion joints, and absorb critical impact energy instead of shattering the target substrate. This matching industrial triplet changes the game entirely by introducing advanced self-sharpening geometric profiles that actively preserve their biting edges under heavy stress, turning your high-velocity rotary hammer drill into a relentless, low-fatigue demolition machine.\u003c\/p\u003e\n\u003cp style=\"font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; line-height: 1.6; color: #333333;\"\u003eThis versatile heavy-duty layout equips your toolbox with three separate application-specific blades to cover everything from precise prying to brutal fracturing. The innovative Star-Point chisel utilizes an aggressive twisting head design that expands its direct shattering footprint while remaining completely loose and jam-resistant inside structural stone or concrete slab floors. For general channeling, concrete line scoring, and mortar bed cleanup, the Viper flat chisel incorporates specialized exterior power ribs that distribute dynamic shockwaves uniformly while sharpening the blade face during operation. Finally, the heavy-duty angled tile chisel slips effortlessly under old mortar backer boards and thinset overlays, clearing stubborn ceramic layers up to 40 percent quicker than standard flat chisels without breaking tiles into millions of problematic shards. Packed inside a resilient, compact storage tube that protects your tool investment on trucks or jobsites, this master scaling set guarantees high-conversion precision and flawless demolition performance shift after shift.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;

Demolition chipping generates immense thermal friction inside the tool holder; running the steel shank dry strips the internal chuck components and accelerates costly repairs. Additionally, make sure your tool is locked strictly into \"Hammer-Only\" mode; letting a chisel spin in full rotation mode can destroy the blade profile and ruin your workpiece. \u003c\/span\u003e\u003c\/p\u003e","brand":"BOSCH","offers":[{"title":"Default Title","offer_id":52330052682039,"sku":"HS143PK","price":28.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2274\/5945\/files\/Bosch_3_Piece_SDS_Plus_Bulldog_Self_Sharpening_Demolition_Hammer_Chisel_Set_Star_Point_Flat_Viper_Tile_Scraping_Concrete_Breaker_Scaling_Tool_Kit.jpg?v=1780432722","url":"https:\/\/www.1toptools.com\/products\/bosch-3-piece-sds-plus-bulldog-self-sharpening-demolition-hammer-chisel-set-star-point-flat-viper-tile-scraping-concrete-breaker-scaling-tool-kit","provider":"1 Top Tools","version":"1.0","type":"link"}
