The 4-cutter full carbide head is produced using Tri-Metal Fusion Welding, giving it impact resistance against rebar and resistance to heat up to 1800 degrees F, compared to 800 degrees F for standard bits. A removable stainless-steel sleeve pairs with a Snap-Lock Adapter (sold separately) to create a two-step dust extraction system that removes up to 97 percent of dust and debris from the hole. Licensed HVAC, plumbing, electrical, and concrete trades installing anchors, epoxy anchors, or conduit penetrations in reinforced concrete slabs or walls will find this bit relevant to daily production work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for anchor-setting applications in residential and commercial construction where reinforced concrete is present. The 4-inch working length and 1\/2-inch diameter match common anchor bolt and epoxy anchor specifications. The integrated dust extraction capability eliminates the traditional blow-brush-blow cleaning method, allowing epoxy or anchor placement immediately after drilling. The design addresses OSHA silica dust exposure requirements by removing airborne silica at the source, making it applicable for interior overhead drilling, exterior work, and enclosed spaces where dust control is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-cutter tungsten full-carbide head withstands rebar impact by taking controlled small bites, reducing vibration and delivering up to 7 times longer bit life\u003c\/li\u003e\n  \u003cli\u003eDura-Carbide construction rated to 1800 degrees F, more than double the 800 degrees F threshold of standard drill bits\u003c\/li\u003e\n  \u003cli\u003eTri-Metal Fusion Welding bonds the full-carbide head to resist heat and prevent breakage under extreme impact\u003c\/li\u003e\n  \u003cli\u003eRemovable stainless-steel sleeve enables two-step dust extraction, removing up to 97 percent of dust and debris without secondary cleaning steps\u003c\/li\u003e\n  \u003cli\u003ePrecision 90-degree pyramid-shaped tip provides centering stability and accuracy for clean, precise hole starts in reinforced concrete\u003c\/li\u003e\n  \u003cli\u003eVisible wear mark confirms drilling diameter accuracy throughout the life of the bit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SDS-Plus rotary hammer drills.

Verify the hammer drill is powered off and the bit is fully seated in the chuck before drilling. When using the dust extraction sleeve, connect to a compatible vacuum system per OSHA silica dust control requirements before beginning work. Do not use this bit in rotation-only mode; SDS-Plus hammer mode is required for proper carbide head engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: SDS-Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Full Carbide Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutters\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack 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: DIABLO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DMAPLA4440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIABLO","offers":[{"title":"Default Title","offer_id":51524817256754,"sku":"DMAPLA4440","price":64.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d316344d83e333b86508caa51e335574_b03f6dba-f84e-451a-a001-e470940d6d1d.png?v=1785458428","url":"https:\/\/voomisupply.com\/products\/diablo-dmapla4440-sds-plus-hammer-drill-bit-1-2-in-x-10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
