The 1 2 unc spiral flute tap and drill set delivers robust threading capability for medium to large-diameter applications. This substantial combination tool produces 10.8Mm thread diameter with a generous 29mm threading length, making it well-suited for structural metalwork, machinery assembly and heavy-duty fabrication projects where reliable half-inch unc threads are required. The high-speed steel construction with steam-tempered coating ensures consistent performance throughout the tool's service life. The 9mm connection diameter provides solid engagement with power tool chucks, whilst the two-flute spiral design evacuates swarf efficiently during operation. Whether you're working in a professional workshop or tackling home engineering projects, this combination tool eliminates the traditional two-step process of drilling followed by tapping.
