Infinity Tools Wood Tap Sets

A Tradition Of Strength The history of nuts and bolts is fascinating. Today they are mostly associated with metalworking but that wasn't always the case. Early woodworkers of the Middle Ages used threaded joinery in engineering projects like flour mills, winches, and watermills. Using wooden threads and bolts eventually became impractical due to the ever-growing complexity and the size of machines that required stronger mechanical fasteners. Modern woodworkers have been tapping threads into wood for installing workbench hardware, making custom jigs and fixtures, and even creating knockdown furniture. It simplifies construction, allows for easy assembly and disassembly, and produces very strong joints. But until now woodworkers have had to use metalworking taps to make threads in wood and the results have been less than ideal because taps for metal don't have the necessary geometry or clearance for cutting wood and they don't produce a proper thread. Made Specifically For Wood We've designed our new Woodworking Taps to produce clean and sharp threads in your choice of hard or softwood. They're made of high-speed steel and are machined to a tight tolerance for precision and accuracy. We apply our proprietary Chrome-Armor plating to each tap for durability, lubricity, and corrosion resistance. Unlike metalworking taps that tend to 'crush' a thread into the wood, our taps cut cleanly and have ideal flute geometry and chip clearance for making defined threads that will accept your choice of bolts. They feed effortlessly into their pre-drilled hole without burning or binding and allow you to drill up to 3-¼" deep while cutting threads almost to the very bottom of a blind hole. And unlike metal working taps that have a square drive, the Infinity Tools Wood Threading Taps have a machined hex shank that won't slip in your drill's chuck. For ease of use and identification, we go the extra mile and laser mark each tap with its thread size and suggested pilot hole diameter for softwood and plywood. For hardwoods, we recommend drilling a pilot hole 1/32” larger than that marked on the shank.  Features Include: Chrome-Armor plated high-speed steel for durability, lubricity, and corrosion resistance. Hex drive shank designed for electric drill use Extra-long relieved shank allow for drilling up to 3-1/4" deep Each tap is laser marked with the thread size and correct pilot hole size for use in softwood and plywood. For hardwoods, we recommend drilling a pilot hole 1/32” larger. 9-Pc.
