Built from high-speed steel (HSS) with a bright polished finish, it delivers clean entry cuts in residential and light commercial applications. The 1\/4 inch hex shank seats securely in standard hex-drive chucks and quick-change bit holders. At 1-1\/4 inches in diameter, this bit handles rough-in work for plumbing, electrical, and HVAC trades where oversized through-holes are required. The 4 inch shank length provides sufficient reach for typical framing and stud work without an extension.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for electricians, plumbers, and HVAC technicians drilling through wood framing, subfloor, and similar materials during rough-in installation. The two-spur design scores the perimeter of the hole before the center blade removes material, helping reduce tear-out on the exit face. It fits any 1\/4 inch hex-drive drill or impact driver, making it a practical addition to a standard trade tool kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch cutting diameter for large-bore rough-in applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability through repeated use\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex shank compatible with standard hex-drive chucks and quick-change holders\u003c\/li\u003e\n  \u003cli\u003e4 inch shank length for reach in typical framing and stud drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-spur tip design helps reduce exit-face tear-out\u003c\/li\u003e\n  \u003cli\u003eBright polished finish with no added coating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/4 inch hex-drive drills and impact drivers commonly used in electrical, plumbing, and HVAC rough-in work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and used by electricians, plumbers, and HVAC technicians during rough-in phases. Secure the hex shank fully in the chuck before operating. Keep drill speed appropriate for the material being drilled and maintain steady, even pressure to avoid deflection. Inspect the cutting edges before each use and replace the bit if spurs or the center blade show damage that could cause binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Spurs\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire-Fishing Hole\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 87920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51543123394866,"sku":"87920","price":15.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1de4820f329046e749ad9c902e265848.jpg?v=1785916028","url":"https:\/\/voomisupply.com\/products\/irwin-87920-spade-blade-drill-bit-1-1-4-inch-hss-hex","provider":"Voomi Supply","version":"1.0","type":"link"}
