Key Advantages

Precision Step Structure:A precision step is added before the cutting edges to reduce material removal, extend tool service life by up to 30%, and achieve stable mirror-grade hole finish with Ra ≤ 0.4μm.

Superior Material & Bonding:Adopts high-hardness steel or tungsten carbide substrate with high rigidity. Optimized brazing process avoids chipping and performance degradation caused by excessive welding temperature.

Ultra-Precision Machining:Tolerance control up to ±0.002mm, suitable for high-speed machining with feed rates 2–3 times higher than carbide or HSS reamers, greatly improving productivity.

Long Service Life:PCD hardness reaches 8000–10000HV, tool life 10–20 times longer than carbide reamers in abrasive materials, reducing tool changes and downtime.

Material Compatibility:Ideal for non-ferrous metals (aluminum, copper, high-silicon aluminum alloy), composites (CFRP), abrasive materials.NOT suitable for ferrous metals such as steel due to chemical reactions.

1.Adding a precision step before reamer edges minimizes material removal, boosting tool longevity by 30% and achieving mirror-grade hole finishes (Ra ≤ 0.4μm).

2.Weak Brazing Between Tool Body & PCD Inserts Causes Chipping. Excessive Welding Temperature Degrades PCD Performance..

3.The substrate of the tool is either high-hardness steel or tungsten steel. If the rigidity of the tool body is good, it will greatly improve the service life and performance of the tool.
