Dowel Drill Bit with Stop Collar is the largest bit in Kreg's dowel drilling lineup, sized to match Kreg's 1\/2 in. fluted dowel pins for joinery that needs maximum holding strength — heavier furniture, structural shelving, and larger-format cabinetry. Model number KDDB500.\u003c\/p\u003e\n      \u003cp\u003eOne detail sets this bit apart from its 1\/4 in. and 3\/8 in. counterparts in the same family: a 1\/2 in. cutting diameter is larger than the standard 3\/8 in. chuck opening found on most drills, which would normally mean needing a 1\/2 in.-capacity drill just to use it. Kreg solves that with a reduced shank — the cutting head stays a full 1\/2 in., but the shank steps down to a size that fits a standard 3\/8 in. chuck. That means you can run the largest dowel bit in this system with the same drill you already use for the 1\/4 in. and 3\/8 in. bits.\u003c\/p\u003e\n      \u003cp\u003eThe 118-degree split-point tip carries over from the rest of the lineup, and it matters just as much here — arguably more, since 1\/2 in. dowel joints tend to show up in heavier assemblies where a misaligned hole is a bigger problem to fix. The split-point geometry bites into the material immediately rather than wandering, keeping hole placement accurate on the largest, highest-stakes joints in this system.\u003c\/p\u003e\n      \u003cp\u003eHigh-speed steel construction and the included stop collar work the same way here as on the smaller bits: HSS keeps the cutting edge sharp through repeated holes so diameter stays consistent, and the stop collar locks in a drilling depth you set once and then repeat across the whole project without remeasuring.\u003c\/p\u003e\n      \u003cp\u003eWho should buy this: woodworkers and furniture builders using Kreg's 1\/2 in. dowel pins for heavy-duty joinery — table legs, aprons, structural shelving brackets, and similar work where maximum dowel strength matters. For lighter joinery, Kreg's 1\/4 in. and 3\/8 in. dowel drill bits are the better-matched, less material-intensive choice.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eFull-Size Bit, Standard Chuck\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/www.kregtool.com\/dw\/image\/v2\/BDZM_PRD\/on\/demandware.static\/-\/Sites-master-kreg\/default\/dw81b67cd6\/images\/hi-res\/KDDB500-01.jpg\" alt=\"Kreg 1\/2-in. dowel drill bit with stop collar and reduced shank for dowel joinery\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eA 1\/2 in. cutting diameter with a reduced shank means this bit chucks up in the same 3\/8 in. drill you already use for the smaller sizes in this system.\u003c\/p\u003e\n          \u003cul\u003e\n          \u003cli\u003eReduced shank fits standard 3\/8 in. drill chucks\u003c\/li\u003e\n          \u003cli\u003eFull 1\/2 in. cutting diameter for maximum-strength dowel joints\u003c\/li\u003e\n          \u003c\/ul\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n  \u003cdetails id=\"product-benefits-2\" class=\"acc flip\"\u003e\n    \u003csummary\u003e\u003ch2\u003eAccuracy That Matters on the Big Joints\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/www.kregtool.com\/dw\/image\/v2\/BDZM_PRD\/on\/demandware.static\/-\/Sites-master-kreg\/default\/dwb5f36187\/images\/hi-res\/DOWEL-DRILL-BITS-Feature-05.jpg\" alt=\"Split-point tip detail on the Kreg dowel drill bit\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003e1\/2 in. dowel joints show up in heavier assemblies where a misplaced hole is a bigger problem — the split-point tip keeps it accurate.\u003c\/p\u003e\n          \u003cul\u003e\n          \u003cli\u003e118-degree split-point tip for precise starts\u003c\/li\u003e\n          \u003cli\u003eSized to match Kreg's 1\/2 in. fluted dowel pins\u003c\/li\u003e\n          \u003c\/ul\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"tnincluded-wrapper\"\u003e\n        \u003cul\u003e\n        \u003cli\u003e(1) 1\/2 in. high-speed steel dowel drill bit with reduced shank\u003c\/li\u003e\n        \u003cli\u003e(1) stop collar with hardware\u003c\/li\u003e\n        \u003c\/ul\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-key-specifications\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n\u003ctable class=\"aplusspecs\"\u003e\n\u003ctr\u003e\n\u003cth\u003eBit Diameter\u003c\/th\u003e\n\u003ctd\u003e1\/2 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTip Angle\u003c\/th\u003e\n\u003ctd\u003e118-degree split-point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eHigh-speed steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShank\u003c\/th\u003e\n\u003ctd\u003eReduced (fits 3\/8 in. chucks)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-compatibility\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"compat-list\"\u003e\n      \u003cdiv class=\"compat-row\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/drill-bits.svg\" alt=\"\" class=\"icon-sm\"\u003e\n        \u003cdiv\u003e\n          \u003cstrong\u003eDowel System\u003c\/strong\u003e\n          \u003cdiv class=\"compat-detail\"\u003eMatches Kreg's 1\/2 in. fluted dowel pins (KD500-20) for correct hole-to-dowel fit.\u003c\/div\u003e\n        \u003c\/div\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"compat-row\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/handle.svg\" alt=\"\" class=\"icon-sm\"\u003e\n        \u003cdiv\u003e\n          \u003cstrong\u003eJig Compatibility\u003c\/strong\u003e\n          \u003cdiv class=\"compat-detail\"\u003eWorks with the Kreg 1\/2 in.
