Winway is a trusted China manufacturer of high-performance PCD cutting tools for PCB. These brazed polycrystalline-diamond rotary cutting tools are developed for heavy-duty, high-abrasion printed circuit board production, covering V-score grooving, gold-finger bevel chamfering, raw-material slitting and special corner-radius forming processes.
PCB process engineers often ask what PCD cutting tools for PCB are and which production scenario suits them. Improper tool selection leads either to unnecessary high procurement cost or to insufficient service-life performance.
PCD cutting tools for PCB are high-wear-resistant rotary cutting components that use a cemented-carbide substrate with brazed PCD polycrystalline-diamond cutting edges.
They are installed on PCB V-cut machines, bevel chamfer machines, slitting equipment and special corner-rounding machines for high-glass-content PCB processing.
The Winway PCD range covers four core product families, each built for a specific step in high-abrasion PCB production.
PCD-tipped V-scoring tool for high-glass-content PCB, delivering stable groove depth and long service life in continuous V-cut production.
Brazed PCD bevel cutter for gold-finger chamfering on high-abrasion laminates, with a mirror-passivated edge for smooth bevel surfaces.
PCD diamond composite cutting edge on an alloy-steel substrate, designed for cutting FR-4, multilayer PCB and aluminium-based substrates.
Combined PCD corner-radius forming tool for high-volume PCB contour processing, available in custom R-radius and step profiles.
PCD material delivers extraordinary anti-abrasion performance and is specially oriented to continuous high-volume production of high-Tg, high-glass-content and aluminium-base PCB laminates.
PCD tools are constructed with a carbide substrate brazed with polycrystalline-diamond cutting edges. On high-glass-content PCB, their service life can reach 5–20 times that of ordinary carbide counterparts.
However, PCD material is relatively brittle. Hard foreign impurities inside boards can easily cause PCD edge chipping, and the initial procurement cost is higher.
| Consideration | PCD Cutting Tools for PCB | Carbide PCB Cutting Tools |
|---|---|---|
| Cutting material | Carbide substrate brazed with polycrystalline diamond | Integral ultra-fine-grain cemented carbide |
| Wear resistance | Very high; 5–20× carbide life on high-glass PCB | Moderate |
| Impact / chipping resistance | Relatively brittle; sensitive to hard inclusions | Good; tolerates hard-particle impact |
| Initial tool cost | Higher | Lower |
| Best fit | High-glass-content / high-Tg laminates, aluminium-base PCB, continuous mass production | Medium-to-low-abrasion substrates, small-to-medium batches, frequent material switching |
Winway is a professional manufacturer of PCD PCB cutting tools, completing brazing, grinding, edge passivation and inspection internally — unlike traders who outsource core brazing procedures.
Selected mainstream PCD models are kept in limited stock for prompt delivery. A sample-trial service is available for new-project real-machine verification: provide machine spindle specifications, PCB drawing, substrate glass-fiber content and thickness, and our team will give a professional tool recommendation and supply trial samples.
Drawing-based OEM / ODM custom manufacturing is supported for non-standard dimensions and combined tool sets.

Actual PCD tool service life is heavily affected by PCB glass-fiber content, cutting parameters and dust-removal status. High-glass-content and high-Tg PCB accelerate abrasive wear.
Winway provides a manufacturing-defect warranty that includes PCD brazing-joint defects. Damage caused by foreign-object impact, improper clamping or over-limit cutting load is outside the warranty scope. A fixed running-hour warranty is not provided because workshop operating conditions differ greatly.
PCD cutting tools are the optimal option for high-volume, continuous-run production of high-glass-content, high-Tg and aluminium-base PCB. If your production is small-batch with frequent material switching, the carbide series may offer better comprehensive cost-performance.
Not recommended. At high cutting temperature, PCD diamond undergoes chemical graphitization when contacting ferrous metal, causing rapid tool failure.
Only simple abrasive wear can be re-sharpened. If PCD-layer peeling, large-area chipping or substrate cracking occurs, the tool must be scrapped directly and cannot be repaired.
Main causes include hard foreign inclusions inside the PCB panel, excessive single-cut depth, large clamping run-out and machine vibration. Good dust collection and raw-sheet pre-inspection reduce chipping probability.
