The precision tip geometry eliminates bit wander and bit walking at the start of a hole, a common failure point when working on hard, slick surfaces. The reinforced carbide head resists cracking under the stress of hard-material drilling and extends service life compared to standard masonry bits. The 3-flat shank design locks into the chuck to prevent slippage during operation. Plumbers, tile setters, electricians, and general contractors reach for this bit when punching holes through ceramic, porcelain, or glass in residential and light commercial applications.\u003c\/p\u003e\u003cp\u003eThe GT900 is suited for installations where penetrations must pass through tile or glass substrates. Typical scenarios include setting fixtures through tiled shower walls, mounting hardware through backsplash tile, and creating penetrations through glass panels. The innovative drill geometry allows faster material removal compared to conventional spear-point glass bits, reducing heat buildup and the risk of surface cracking. This listing includes a package quantity of 5 bits, making it practical to keep spares on the truck for production work or high-volume tile jobs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision tip eliminates bit wander and walking on slick glass and tile surfaces\u003c\/li\u003e\n\u003cli\u003eHigh-quality carbide tip with reinforced head resists cracking and extends bit life\u003c\/li\u003e\n\u003cli\u003e3-flat shank prevents chuck slippage during drilling\u003c\/li\u003e\n\u003cli\u003eInnovative geometry promotes faster drilling and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003e7\/8-inch diameter suits common fixture and hardware penetration sizes\u003c\/li\u003e\n\u003cli\u003eSold in a 5-pack for production use or truck-stock replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3-jaw drill chucks accepting a 3-flat shank; suitable for drilling ceramic tile, porcelain tile, and glass in residential and light commercial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by trade professionals including tile setters, plumbers, and electricians working with hard tile or glass substrates. Use with a variable-speed drill; start at low RPM with light pressure to allow the precision tip to seat before increasing speed. Apply water or cutting fluid to the work surface to manage heat when drilling glass. Never use this bit with a hammer drill setting, as percussion will crack tile and damage the carbide tip.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.65 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROBERT BOSCH TOOL GROUP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GT900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOSCH","offers":[{"title":"Default Title","offer_id":51564044878130,"sku":"GT900","price":130.09,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e16c5bb56c034a53fe40548c609a04d.jpg?v=1786509424","url":"https:\/\/voomisupply.com\/products\/bosch-gt900-7-8-inch-glass-tile-drill-bit-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
