Diamond micro-diameter end milling tools are more suitable for machining flat surfaces, grooves, and step features, particularly in applications requiring high efficiency and precision.
Need a sample for trial or a custom micro geometry? Contact our tooling engineers with your part drawing and volume — we’ll recommend the optimal flute, helix and edge prep for your workpiece.
Premium single-crystal diamond micro end mills engineered for ultra-precision milling where tolerance, surface finish and stability matter. Our micro-diameter series delivers razor-sharp cutting edges with extreme concentricity and minimal runout — ideal for producing fine grooves, steps, slots and mirror-smooth faces on non-ferrous metals and hard brittle substrates. Because the cutting edge is single-crystal diamond, parts come off the machine with dramatically reduced burrs and reduced need for secondary polishing, saving cycle time on high-mix, low-volume production.
Installed on the high-speed machining center, a Diamond Micro-Diameter End Milling Tool is a kind of ultra-precision machining tool, which is mainly used in the processing of non-ferrous metals and non-metallic hard brittle materials such as nickel, copper, optical glass and silicon wafers.
Diamond micro-diameter end milling tools are more suitable for machining flat surfaces, grooves, and step features, particularly in applications requiring high efficiency and precision.
Application
Precision electronics and semiconductors: For micro-groove processing of semiconductor wafers, micro-element fabrication for integrated circuit packaging, and micro-hole drilling of high-density printed circuit boards.
Precision mold and injection: Used for manufacturing precision injection molds, fine feature parts of stamping molds.
PCB and micro-electronics component machining, precision optical component trimming, medical micro-parts, and small structural components in consumer electronics. These tools excel wherever tight radii and near-mirror finishes are required.
Our micro end mills combine single-crystal cutting edges with a rigid carbide body and precision balancing to minimize chatter and deliver repeatable surface quality across long runs — reducing rejects and rework. We offer custom geometries, special coatings (on request) and small-batch production to match your process.
① After-sales Services
We have professional after-sales service team and after-sales system which called "Litian Century after-sales system". This system is used to manage the information of after-sales maintenance products, and can realize the functions of inquiring the grinding progress, grinding cost and feedback of after-sales problems. Advantages of the system: "zero consultation, more time saving, more convenient, more efficient", users can log in at any time to check.
② Quality Assurance
The company is equipped with advanced inspection equipment and trained inspection personnel which assure us carry out inspections during each process. At the same time, every single tool can be sent to our customers after the professional inspection by Quality Control Center.
③ Repair Service
For the multi-way tools which can be repaired, we can bring your monocrystalline diamond tools back to "new tool" condition in a very short turnaround time. A after-sales service system is available which can let you know the condition of your repaired tools in real time.
④ Packages
We customize special packaging box for the tool, in line with the mechanical structure of the human body, that is, convenient disassembly and safe.
⑤ Delivery
We can arrange delivery your goods by air, DHL, FedEx and other ways your need.
Our products enjoy a great reputation for its good surface finish, high precision and complete product variety. We serve the customers from USA, Mexico, Germany, Belgium, Russia, South Africa, Egypt, India, Pakistan, Korea, Japan and all Southeast Asian countries.
