Woodworkers, this dowel center set is about to become your new best friend for perfect alignments! The 32-piece collection includes both solid and hollow dowel centers in four super useful sizes: 1/4 inch (6mm), 5/16 inch (8mm), 3/8 inch (10mm), and 1/2 inch (12mm). Made from durable chrome-plated metal that resists rust and corrosion, these little guys are built to last through project after project. Here's how they work: drill holes in your first piece of wood, pop these centers into the holes, press your second wood piece against them to mark the exact positions, then drill your matching holes. Boom - perfect alignment every time! No more guessing, no more misaligned cabinets or furniture pieces. Whether you're building cabinets, assembling furniture, or working on any woodworking project that requires precise joining, these transfer plugs save you time and frustration. The chrome finish means they slide in and out easily without sticking. Keep them organized in your toolbox and pull them out whenever you need dead-accurate hole matching. Your woodworking projects just got way more professional!
