{"title":"AT Hole Enlarging Core Drills","description":"\u003cp\u003e\u003cspan\u003eAlfa Tools manufactures hole enlarging core drills (also called shell drills or core reamers), specialized 4-flute high-speed steel cutting tools designed to enlarge existing holes with precision and efficiency. Unlike standard twist drills that require a solid starting point, these core drills feature a hollow center that allows them to cut around an existing hole, removing only the material needed to reach the desired diameter. This design eliminates pilot drilling, reduces cutting forces, improves accuracy, and extends tool life. Ideal for machinists, fabricators, maintenance technicians, and manufacturing professionals who need to enlarge pre-drilled, punched, cored, or cast holes in steel, aluminum, cast iron, and other metals.\u003c\/span\u003e\u003c\/p\u003e","products":[{"product_id":"hed133","title":"Alfa Tools HED133 9\/16\" HOLE ENLARGING CORE DRILL","description":"\u003ch4\u003eShort Description\u003c\/h4\u003eALFA TOOLS HED133 Hole Enlarging Core Drills, 9\/16\" Hole Size, 0.5625 Decimal Equivalent, 1\/2\" Shank Size, 3\/8\" Minimum Starting Hole Size, 1-7\/8\" Flute Length, 4-5\/16\" Overall Length, High Speed Steel, 4 Flute, 3 Flats on Shank, Black \u0026amp; Gold Finish, Right Hand Spiral,  \u003cbr\u003eUPC: 721511291021\u003cbr\u003e\u003cb\u003e*All Alfa Tool orders must meet a $50 minimum.*\u003cbr\u003e\u003c\/b\u003e\u003cbr\u003e\u003cb style=\"color:red\"\u003eAlfa Tools products can only be purchased if you have a shipping account.
