The bit is tipped with tungsten carbide, which provides the hardness needed to score and drill these materials without causing fractures or edge chipping. At 5\/16 inch diameter, it suits a range of common hole-sizing tasks on tile installations, glass panels, and similar applications. This bit is sold individually and is suited for use by tile setters, glaziers, plumbers, and other trade professionals who regularly drill into non-wood hard surfaces.\u003c\/p\u003e\n\u003cp\u003eThis bit is appropriate for residential and light commercial applications where holes must be drilled through ceramic tile, porcelain, or glass without cracking the substrate. Typical use cases include installing fixture mounting hardware through tiled walls, creating penetrations in glass panels, and drilling anchor holes in tile backsplashes or flooring. The 5\/16 inch diameter makes it a practical choice for standard anchor and fastener clearance holes in tile work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTungsten carbide tip provides hardness necessary for glass and tile penetration\u003c\/li\u003e\n  \u003cli\u003eSpear-point geometry helps center the bit and reduces lateral movement on slick surfaces\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch drill diameter suits common anchor and fastener clearance applications\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-bit replacement or addition to an existing set\u003c\/li\u003e\n  \u003cli\u003eCarded packaging for easy storage and identification at the job site\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard rotary drills and drill-drivers when used at low speed without hammer mode.

A licensed tile setter or general tradesperson should apply steady, moderate pressure and use water or cutting fluid as a coolant to extend tip life and reduce the risk of thermal cracking in the substrate. Mark the drill point with tape or a center punch guide to prevent the bit from walking on smooth surfaces before the pilot hole is established.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Tungsten Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Style\u003c\/strong\u003e: Spear Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Glass and Tile Drill Bit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging Type\u003c\/strong\u003e: Carded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 042526505201\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: IR50520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51347398852914,"sku":"IR50520","price":45.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499711.jpg?v=1782103754","url":"https:\/\/voomisupply.com\/products\/irwin-ir50520-glass-tile-drill-bit-5-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
