With a 1\/4-inch hole diameter and 4-inch overall length, this bit fits standard rotary drills and accepts a 1\/4-inch straight shank. The economy-grade carbide tip provides adequate hardness for occasional-use masonry applications, making it a cost-effective option for tradespeople who need a reliable bit for anchor and fastener hole prep on the jobsite.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for residential and light commercial applications where a 1\/4-inch pilot or anchor hole is needed in masonry substrates. Common install scenarios include mounting electrical boxes, brackets, conduit straps, and HVAC equipment supports to concrete or CMU walls. The straight shank fits standard 3-jaw chuck rotary drills without requiring a specialty tool holder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide tip construction for drilling into concrete, brick, and block\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hole diameter for standard anchor and fastener sizing\u003c\/li\u003e\n  \u003cli\u003e4-inch overall length provides reach for typical wall-mount applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight shank fits standard 3-jaw chuck rotary drills\u003c\/li\u003e\n  \u003cli\u003eEconomy rotary design suited for intermittent jobsite use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement masonry bit compatible with standard 3-jaw chuck rotary drills accepting a 1\/4-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and used by electricians, HVAC technicians, plumbers, and general tradespeople performing masonry anchor work. Use with a variable-speed rotary drill at moderate speed to avoid overheating the carbide tip. Do not use with hammer-drill or SDS mode, as straight-shank carbide bits are not rated for percussive impact. Keep drilling pressure steady and allow the bit to clear dust periodically by backing out during deep holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Type\u003c\/strong\u003e: Rotary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Type\u003c\/strong\u003e: Carded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 042526611162\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: IR61116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51346268815666,"sku":"IR61116","price":19.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499693.jpg?v=1782075802","url":"https:\/\/voomisupply.com\/products\/irwin-ir61116-masonry-drill-bit-1-4-x-4-inch-carbide-tip","provider":"Voomi Supply","version":"1.0","type":"link"}
