Thread Mill Inserts, also known as helical insert inserts or threadforming taps, are high-precision cutting tools designed to create internal threads in a workpiece with minimal burrs or deformation, providing uniform and consistent threaded holes for fasteners. These inserts have a specially shaped profile to achieve strong threaded joints that prevent loosening under stress. With their ease of installation and excellent accuracy, thread mill inserts are ideal for applications requiring blind or partially-tapped holes in difficult materials such as stainless steel, carbon steel, cast iron, or titanium alloys where taps might break or damage the hole, especially in automotive engines, dies & molds, hydraulic components or plumbing fittings.
