  • UFO Thread Milling Cutter
    UFO Thread Milling Cutter

    UFO thread milling cutter was developed to solve the problems of diverse thread size and small volume requirement. Y.T. UFO thread inserts are used on CNC machine and with the help of threading program, one insert can be used to make several types of threads such internal threads, external threads, pipe thread with different sizes. These inserts can be used in small machines for machining large size threads and high precision requirement threads. This will result in reducing purchasing cost on taps.Other type of straight thread mill insert can make only one type of thread. These types of thread mill inserts require heavy cutting power. However, Y.T. indexable thread mill unlike others can make huge threads in small machines. The entire series are available in 55°, 60°. Insert diameters are available in Ø 12, Ø 15, Ø 20, Ø 25. All the required cutting parameters are available in the catalog. Using programming, various kinds of threads can be achieved.


  • Chamfer King Exclusive for Drilling Machines
    Chamfer King Exclusive for Drilling Machines

    Special design Y.T. indexable chamfer is exclusively for drilling machines and pneumatic machines. It has patented carbide strip design best suitable for unstable machining conditions such as manual drilling machines and plastic materials where there are high chances of burr issues. User does not have to change insert for each type of material. Insert has only one grade for all materials. The cutter does not require regrinding but just need to change the insert when it wears out. There are no burrs on the material after machining.The insert is highly economical available with two cutting edges and one grade for all kinds of materials. We have complete range of specs available from Ø 4 ~ Ø 110 and angles 60°, 90°, 120°. Besides CNC machines, the cutter can also be used on drilling machine, pneumatic machine, electric machine, hydraulic machine etc. Due to its versatile applications, it is called "Chamfer King".

  • Indexable Saw Blade
    Indexable Saw Blade
    SB Series

    Mainly used for side milling application. It is suggested that smaller the diameter cutter better the performance of the tool. If the small diameter cutter used, it will give better stability and increase insert tool-life.


  • Indexable Saw Blade
    Indexable Saw Blade
    SBL Series

    It is used on face milling arbor. You shorten the length of the arbor by connecting with BL / BLL which will provide better stability and increase the tool-life.


  • Indexable Spiral Point Tap
    Indexable Spiral Point Tap
    Indexable TAP

    Effective chip breaking and easy chip removal are the most important factors for any machining process. Y.T.'s special geometry design of the tap insert makes it one of its kinds in chip breaking function. Hence, it will make a great impact on difficult materials, high hardness materials and mass productions materials. Our standard tap sizes are from M10 up to M64 in JIS, DIN form with various kinds of shank lengths. The standard tolerance is 6H. We also take special tolerance, special length requirements.


  • Indexable Cold Form Tap
    Indexable Cold Form Tap
    Indexable TAP

    Cold Form tap, which is also known as Fluteless Tap used in sufficient horsepower machines for internal threads by pressure deformation process without chip removal. It can produce high quality pitch angles as well as better tool-life. It is best applicable on ductile materials. One shank can fit in both spiral point inserts as well as cold form inserts, which will reduce your cost and inventory. Sizes available from M14 to M64.


  • Taper Pipe Thread Tap
