The rock carbide tip delivers the impact resistance needed to cut through concrete, brick, block, natural stone, and artificial stone without premature wear. At 1\/8 inch in diameter and 3 inches in overall length, this bit is sized for anchor pilot holes and other small-bore masonry work. It fits standard 3\/8-inch and 1\/2-inch keyed or keyless chucks, making it compatible with the rotary hammer drills and hammer drills already on most job sites.\u003c\/p\u003e\n\u003cp\u003eThis bit is used primarily in residential and commercial construction and renovation where mechanical anchors must be set into masonry or concrete substrates. Typical applications include setting sleeve anchors, drop-in anchors, and similar fasteners in foundation walls, concrete slabs, block walls, and stone. The 1\/8-inch diameter is well suited for light-duty anchor applications where a small pilot or full-diameter hole is required in confined spaces or near edges where larger bits could cause spalling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRock carbide tip resists wear during percussion drilling in concrete, masonry, and stone\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch diameter x 3-inch length sized for small anchor pilot holes\u003c\/li\u003e\n  \u003cli\u003eFits standard 3\/8-inch and 1\/2-inch drill chucks\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with rotary hammer drills and standard hammer drills in percussion mode\u003c\/li\u003e\n  \u003cli\u003eSold individually — one bit per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8-inch and 1\/2-inch chuck hammer drills and rotary hammer drills used in masonry and concrete drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove this bit only with the drill powered off and the chuck fully released. Wear appropriate eye protection and a dust mask when drilling masonry or concrete, as silica-containing dust is generated. Drilling should follow applicable OSHA silica exposure guidelines and any local jobsite safety requirements. Do not use this bit in a standard drill without percussion or hammer mode engaged, as this will cause rapid tip wear and may damage the substrate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Rock carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Compatibility\u003c\/strong\u003e: 3\/8-inch and 1\/2-inch standard chucks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Masonry, concrete, rock, artificial stone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 028874052215\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: DEWALT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DW5221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51342720467250,"sku":"DW5221","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310493327.jpg?v=1782004641","url":"https:\/\/voomisupply.com\/products\/dewalt-dw5221-percussion-hammer-drill-bit-1-8x3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
