At Wangdefu, we understand the challenges of machining large, deep holes with high accuracy. Our PCD Guide Bar Reamers are engineered to provide:
High straightness and roundness for L/D ratios up to 20
Mirror-finish hole walls without secondary polishing
Consistent performance for repetitive high-volume production
These reamers are ideal for materials like high-silicon aluminum, magnesium, carbon fiber composites, graphite, ceramics, and sapphire.
Why Choose Wangdefu
PCD Cutting + Diamond Guide Bars
Ensures minimal runout (≤0.002mm) and excellent support for long-overhang applications
Maintains precision under heavy-duty machining
Low Friction & Burr-Free
Prevents built-up edge and sticking on non-ferrous metals
Laser-ground, mirror-polished edges achieve Ra0.1–0.4μm
Robust Body & Modular Design
High-strength carbide base with replaceable inserts
Reduces long-term costs and allows high-speed operations
Customizable & Versatile
Diameter range φ15–φ250mm, straight or spiral flutes
Optional high-pressure internal coolant channels for deep or composite holes
