The FNL 3297127 Flute H3 Screw Thread Sti Bottom Tap is a high-quality tool designed for precision machining and thread cutting applications. This tap is specifically designed for use with H3 (UNC-3) thread forms, making it an ideal choice for projects requiring threads with a 0.473 inches (12 mm) pitch and 0.145 inches (3.7 mm) major diameter.
The tap is constructed from hardened steel, ensuring durability, strength, and resistance to wear and tear. The hardened material allows the tap to cut threads smoothly and accurately, reducing the risk of stripping or other damage to the workpiece. The tap's H3 flute design provides excellent chip evacuation, reducing the likelihood of buildup and ensuring a clean, accurate cut.
The tap features a bottom thread design, with a straight threaded section at the bottom that allows it to be used in blind holes or when tapping from both sides of the workpiece. This design also makes it easier to start the tap in the hole, reducing the risk of breakage or damage.
The tap's STI (self-tapping insert) bottom thread design is a particularly useful feature. This design allows the tap to cut a thread into a blank or soft material, such as aluminum or brass, without the need for a pre-drilled hole. This can save time and effort, as well as reduce the risk of damage to the workpiece.
The FNL 3297127 Flute H3 Screw Thread Sti Bottom Tap is a versatile and reliable tool for a wide range of machining and thread cutting applications. Its hardened steel construction, H3 flute design, and bottom thread design make it well-suited for use in a variety of materials, from metals to soft plastics. Whether you're a professional machinist or a DIY enthusiast, this tap is a valuable addition to your toolkit.
