1.High Rigidity Improve surface finish and perpendicularity. Made of pure tungsten carbide material, excellent rigidity, good shock absorption, no distortion as lateral stiffness too large. 2.High Precision Improve dimensional precision. To extend the processing depth, enhance the accuracy of processing & to achieve long, ultra-deep, ultra-high precision machining possibilities. 3. High Efficiency No welding fracture concerns, emphasizing the variability of the replaceable tool head, a carbide bar can reach dozens of combinations, widely used in Rough & precision processing industrial . 4. Reduce Cost Extending the tool life. The Holder can be reused even if the cutter is damaged and Easy and convenient to replace. The tip and the Holder are screwed and run in reverse direction to the spindle.
