    Customized Tools With Indexable Inserts

    The most efficient CNC cutting tools, unlike traditional tools.

    The installing error could be avoid by choosing customized tools with indexable inserts. Because boring head and cartridge are unified as a whole, it don't need two stage install any more.

    It helps achieve the highest-precision machining target and utmost work efficiency in mass production.

    • Indexable Inserts
      Special indexable inserts can be supplied according to customers' requirements.
    • Adjustable Frames
      Supply adjustable frames for insert pocket to get a high repeatability.
    • Kinds Of Adapter System
      To meet different manufacturing machines, we can design and customize sorts of holder structures including shrink fit chuck and hydraulic chuck, with different cone, such as HSK and BT.
    • Customized Inserts
      On request, customized inserts are available, including ground inserts with sophisticated cutting edge and PCD/CBN inserts.

    Integrated Special Tools

    Widely used in the manufacturing industry

    Derek designs the most suitable tool structure, covering the tip type, the cooling method, the geometric shape, the processing parameter, etc.) specially for each type of a customer's tool based on the material of the processed and the customer's real processing conditions whether it is drilling, milling, reaming, boring or any other machining, so as to meet different customers' diversified demands for machining precision, smooth finish, processing efficiency and tool service life.

    Based on two decades' manufacturing experience, Derek's excellent production techniques guarantees the quality of special tools, which are extensively used in metalworking of automobile, aeronautics and astronautics, medical and equipment manufacture industries. Special tools bring down the production cost in mass production dramatically.

    • Stepped Cutting
      Taking cutting condition and work piece into consideration, a stepped special tool can be designed and produced, which not only shortens the processing time but also increases the cutting performance.
    • Special Cutting Edge
      A special cutting edge can be achieved on customers' demand, to finish the sophisticated machining.
    • Optimized Cutting Edge
      Optimized cutting edge promises a smaller cutting resistance, a longer tool life and a better surface performance.
    • Unique Chipbreaker Design
      Special design and optimize the chipbreaker for those tools used in a close cutting condition, which makes the chip-removal easier, cutting edge cooler, and more valid machining.

    Customized PCD Cutting Tools

    With extraordinary cutting performance and tool life

    The artificial polycrystalline diamond and the natural monocrystalline diamond are the known materials with the highest hardness in the nature. The tools made of these two materials enjoy a much longer service life than usual cemented carbide tools. The diamond tool, equipped with high hardness and thermal conductivity as well as low frictional factor, boasts its outstanding cutting performance.

    • Superior Tool Life
      Compared with the usual tools, PCD tools enjoy a superior tool life, which reduces the production cost dramatically.
    • Ground PCD Edges
      The cutting edge of PCD is ground to the special shape to meet an unique metalworking requirement. The tool life can be more than 10,000 times.
    • Mirror Effect
      The surface processed by the PCD tool is always very flat and smooth just like a mirror because of the super-high rotation speed of the PCD tool, which leaves out the customer's polishing procedure.
    • Extraordinary Performance
      With high hardness and thermal conductivity as well as low frictional factor, boasts its outstanding cutting performance, which makes it the only choice in some machining solutions.
    • Extra Chipbreaker
      According to a specific cutting condition, PCD tools with special chipbreakers are available. And it results in a better cutting performance.

    Turn Key Project

    Whatever the project is, we are going to take over it.

    Usually, it takes about 4-5 usual and special tools to machine one small and simple work piece. However, it asks for more than 20 pcs of tools for a sophisticated component. Let's take the airplane manufacturing as an example. Thousands of tools are required during the manufacturing. If one factory wants to produce 5 pcs of work piece at one time, then they have to choose about 100 different tools to finish the work. Derek is ready to offer you well selected tools to finish your work efficiently.

    On the basis of two decades' manufacturing experience, equipped with state-of-the art manufacturing machines, Derek's professional technical staff and service personnel are ready to offer you one-stop service for your project and metalworking demand. On receipt of your drawings of work piece to be machined, we will supply you a full machining solution, including standard tools, special tools, and inserts, which will fulfill your requirement, such as production machines, working environment, lead time of work piece, etc.

    Frequently Asked Questions

    Q What are the main differences between HSK, BT, and SK blank adapters?
    HSK, BT, and SK blank adapters differ primarily in their taper interface and clamping mechanism. HSK adapters use a hollow short taper for high-speed and high-precision applications, offering excellent rigidity. BT adapters feature a 7:24 taper widely used in conventional CNC machining centers. SK adapters also use a 7:24 taper but are designed to the DIN 69871 standard, popular in European machining environments. Each system serves different machine tool spindles and precision requirements.
    Q Can Derek supply customized blank adapters to meet specific machining requirements?
    Yes. Derek provides fully customized blank adapters including HSK, BT, and SK series. Customers can specify dimensions such as diameter (D) and length (L) to match their unique machining conditions. Custom holder structures, including shrink fit chucks and hydraulic chucks, are also available in various taper types.
    Q What are the advantages of using customized tools with indexable inserts?
    Customized tools with indexable inserts eliminate the two-stage installation process by integrating the boring head and cartridge into a single unit. This significantly reduces installation errors, improves machining precision, and enhances work efficiency in mass production. Adjustable frames ensure high repeatability, while special indexable inserts can be tailored to specific customer requirements.
    Q Why should I choose PCD cutting tools over standard carbide tools?
    PCD (Polycrystalline Diamond) cutting tools offer significantly superior tool life compared to standard cemented carbide tools — the cutting edge can last more than 10,000 times longer in some applications. PCD tools deliver a mirror-smooth surface finish, reduce the need for polishing, and perform exceptionally in high-speed machining due to their high hardness, excellent thermal conductivity, and low frictional coefficient. Custom chipbreakers and ground PCD edges are also available for specific cutting conditions.
    Q What industries are Derek's integrated special tools suitable for?
    Derek's integrated special tools are extensively used across a wide range of industries including automotive manufacturing, aeronautics and astronautics, medical device manufacturing, and general equipment manufacturing. These tools are designed for operations such as drilling, milling, reaming, and boring, with customized geometries and cutting edge designs to meet each industry's demanding precision and efficiency standards.
    Q What does Derek's Turn Key Project service include?
    Derek's Turn Key Project service provides a complete, one-stop machining solution. Upon receiving your work piece drawings, Derek's technical team will analyze your machining requirements — including production machines, working environment, and lead time — and supply a comprehensive tooling package that covers standard tools, special tools, and inserts.
