The "Taper Shank Drill for Steel Frames" is a high-efficiency drill for cutting splices that uses HSS-Co. The main sizes of taper shanks, φ18, φ22, and φ24, are unified to MT3. This eliminates the hassle of changing holders and reduces turnaround time. Additionally, the increase in shank diameter significantly enhances holding power, extending the lifespan of both the shank and the holder. 【Features】 ■ Uses HSS-Co ■ Long lifespan specification ■ Sustained cutting capability ■ Newly adopted TIN-H special coating ■ Delivery system prepared for urgent user requests *For more details, please refer to the PDF document or feel free to contact us.

The "shank-mounted thread cutting end mill" is used when the diameter of the internal thread being processed is not very large, and the thread cutting end mill is relatively small in diameter. Its usage is fundamentally the same as that of a large diameter thread cutting end mill. By feeding the workpiece one lead in the axial direction for each rotation of the workpiece, or having the end mill make 1.1 to 1.2 rotations around the inner diameter of the workpiece, cutting continues until a complete internal thread is processed. This results in shorter processing times and greater accuracy compared to thread cutting with a lathe. 【Features】 - The material of the thread cutting end mill is high-speed tool steel containing Co, considering stable tool life. - Upon request, it is also possible to supply versions with carbide tips to enhance tool life. - We can accommodate requests for various shapes of thread cutting end mills. *For more details, please refer to the PDF document or feel free to contact us.

The "screw cutting milling cutter for external threads" includes "single-start thread milling cutter" and "multi-start thread milling cutter." The "single-start thread milling cutter" is tilted to match the lead angle of the screw being cut, and cutting is performed by feeding it up to the length of the external thread. The "multi-start thread milling cutter" is aligned parallel to the screw being cut, and a feed is applied in the axial direction for each rotation of the workpiece, continuing the cutting until the workpiece has rotated 1.1 to 1.2 times, resulting in a complete external thread. 【Features of Our Products】 ■ The material of the thread cutting milling cutter is made of high-speed tool steel containing Co, considering stable tool life. ■ Depending on your requirements, it is also possible to supply tools with carbide tips to enhance tool life. ■ We can accommodate requests for various shapes of thread cutting milling cutters. *For more details, please refer to the PDF materials or feel free to contact us.

There are several uses for thread milling cutters, but the "large diameter thread cutting milling cutter" is formed with a thread profile that has no lead, and it comes with the condition that the length of the threaded section is longer than the processed male thread. By feeding the workpiece one lead in the axial direction for each full rotation of the milling cutter, or by continuing to cut until the workpiece rotates 1.1 to 1.2 times or the milling cutter makes 1.1 to 1.2 revolutions around the inner diameter of the workpiece, a complete male thread is machined. This results in shorter processing times and greater accuracy compared to thread cutting with a cutting tool. 【Features of Our Products】 - The material of the thread milling cutter is made from high-speed tool steel containing Co, considering stable tool life. - Upon request, it is also possible to supply versions with carbide tips to enhance tool life. - We can accommodate requests for various shapes of thread milling cutters. *For more details, please refer to the PDF document or feel free to contact us.

The "Small Diameter Thread Cutting End Mill" is mounted on a dedicated automatic lathe and is primarily used for mass production threading of non-ferrous metal screw parts. This product is formed with leaded threads and synchronously rotates the workpiece and the thread cutting end mill in the same direction, performing thread cutting in one rotation. The types of screws that can be cut range widely from parallel screws such as metric screws and unified screws to pipe taper screws, with various types available depending on the kind of automatic lathe used, including Traub type, Tsugami type, and Tsugami Fuji type. 【Features】 ■ Contributes to cost reduction with high-speed processing that performs thread cutting in one rotation ■ Fine cutting layers are produced due to intermittent cutting, allowing for good chip removal ■ Re-sharpening of cutting edges is also possible *For more details, please refer to the PDF document or feel free to contact us.
