  • Indexable Spot Drill 90°
    Indexable Spot Drill 90°

    1. Close to zero point eccentricity, high accurate centering position, will reduce tap breakage.2. Our special grade C350 provides strong cutting edge and higher cutting speed ranging from 300% ~ 1000%.3. It has multi-function features such as chamfer, engraving and V-grooving. There will be two cutting-edges available when used for chamfering process. It can also be used on drilling machines.


  • 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.


  • 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
    Taper Pipe Thread Tap
    Indexable TAP

    One of the most difficult tapping processes is producing internal taper pipe threads, because it requires large horsepower and does not allow easy chip removal resulting in poor tool-life or easy tap breakage. Y.T. taper pipe thread tap has special geometry design inserts for effective chip breaking and chip removal feature to improve tap tool life and the machining efficiency. Sizes are available form 3/8" up to 2". Both RC and NPT inserts can fit into one shank.


  • Taper Pipe Reamer
    Taper Pipe Reamer
    Indexable TAP

    Many customers come across problems of poor tap life and tap breakage while producing taper pipe thread. As a solution to this Y.T. has designed a Taper Pipe Reamer that define the taper hole first so that it can reduce the resistance and make chip removal easier. In addition to that, both reaming and chamfering can be finished in one process, which also reduces the machining steps.


  • UFO T-slot Cutter
    UFO T-slot Cutter

    "UFO" design is the Y.T.'s innovative-patented insert positioning with tapered polygonal design to achieve higher centering accuracy. The minimum thickness starts from 0.5mm and the available diameters are Ø 10, Ø 15, Ø 20, Ø 25, Ø 30. There is standard stock available for every 0.1mm size in the size under 2.0mm thickness. It has a complete range of specification and very effective chip removal design best for small grooving. This UFO design is available with UFO chamfer insert and UFO Radius insert. All these inserts can fit in a common tool holder. For more details, see "UFO Family Series".
