Winway is a professional manufacturer and supplier of PCD Bevel Cutter for PCB. This cutter features a cemented-carbide substrate with PCD polycrystalline diamond composite segments welded onto the cutting edges. Designed for PCB beveling machines, it produces precise inclined chamfers on PCB gold-finger edges. The standard bevel angle helps reduce insertion resistance and supports reliable electrical contact between connectors and gold fingers.
The cutter uses a high-strength cemented-carbide substrate with PCD polycrystalline diamond welded onto the cutting edges. Its teeth are precision-formed according to the required processing angles. It is mainly used for beveling gold-finger boards made from FR-4 copper-clad laminates and aluminum-base substrates. Compared with conventional tungsten-steel bevel cutters, the PCD cutting edges offer superior wear resistance. They help maintain consistent bevel angles during mass production, reduce edge chipping and copper-foil burrs, and extend tool service life. This makes the cutter suitable for continuous gold-finger beveling operations in PCB manufacturing.
The spindle of the beveling machine drives the cutter at high speed. Its pre-formed PCD cutting edges perform a combined milling and grinding operation along the PCB board edge.
The preset cutting geometry removes excess material from the board edge in a single pass, forming an inclined bevel surface that meets the specified angle requirements.
The diamond cutting particles process the glass-fiber and copper-foil layers, helping reduce glass-fiber pulling, copper-foil flanging and edge burrs.
With a precision-ground cutting profile, the PCD Bevel Cutter for PCB helps maintain consistent bevel angles and depths to meet gold-finger insertion and assembly requirements.
● High Wear Resistance: PCD cutting tips offer greater wear resistance than conventional tungsten-steel cutting edges, supporting longer tool service life.
● Precise Bevel Geometry: Precision-ground tooth profiles help maintain consistent chamfer angles and produce smooth bevel surfaces with fewer burrs.
● Stable High-Speed Operation: Dynamic-balance treatment helps reduce vibration during continuous high-speed beveling.
● Efficient Chip Removal: The optimized flute design helps remove cutting debris and reduce the accumulation of fiber residue.
● Customizable Dimensions: Outer diameter, shank diameter, bevel angle and fillet radius can be customized according to machine and PCB processing requirements.
| Ordinal | Diameter | Shank Diameter | Number of Teeth | Length | Cutting Length |
| 01 | 6 | 6 | 4/6 | 50/67 | 6 |
| 02 | 3.175 | 3.175 | 3 | 50/67 | 5 |
Parameter Note: Custom sizes are available upon request.
Used for bevel chamfering on gold-finger edges of consumer-electronic circuit boards to facilitate connector insertion and assembly.
Suitable for board-edge beveling and deburring on multilayer circuit boards used in communication equipment.

● Confirm Machine Compatibility: Check the beveling-machine spindle dimensions and select the corresponding outer diameter, shank diameter and cutting length.
● Match Bevel Geometry: Select the bevel angle and fillet radius according to the PCB drawing specifications.
● Consider Board Thickness: For thin-board beveling, adjust the feed speed appropriately to help prevent edge chipping.
● Plan for Production Volume: For continuous mass-production applications, the PCD Bevel Cutter for PCB offers a wear-resistant cutting solution that can help reduce tool replacement frequency.
● PCD Tool Production: An independent PCD tool production workshop supports processes from PCD brazing to precision profile grinding.
● Quality Inspection: Finished bevel cutters undergo concentricity, angle and dynamic-balance aging tests before delivery.
● Technical Matching: Technical support is available for matching bevel angles, R-fillet dimensions and cutter sizes to different PCB processing requirements.
● Regrinding Service: Professional PCD tool regrinding helps extend the usable service life of cutters.
● Processing Recommendations: The engineering team provides recommended spindle speed and feed-rate parameters based on application requirements.
A1: PCD diamond cutting edges offer superior wear resistance compared with conventional tungsten-steel cutting edges, particularly when processing glass-fiber-containing boards. The cutter can provide longer service life and more consistent bevel angles during mass production. It also helps reduce board-edge chipping and copper burrs, lower tool replacement frequency and support production efficiency.
A2: It is mainly suitable for gold-finger bevel processing on common FR-4 copper-clad laminates, high-glass-fiber boards and aluminum-base substrates.
A3: Service life depends on board material, machine spindle speed, feed rate and air-blowing or chip-removal conditions. Under comparable working conditions, PCD cutting edges generally last longer than ordinary tungsten-steel cutting edges. Boards with high glass-fiber content may accelerate cutting-edge wear.
A4: These issues are not necessarily caused by the cutter alone. Worn cutting edges, excessive feed speed, insufficient air blowing and chip removal, or excessive spindle runout can contribute to copper burrs. If burrs appear when using a new cutter, check the machine parameters and air-blowing conditions first. Regrinding may be required when the cutting edges become worn.
A5: Although cutter angle accuracy is controlled before delivery, bevel-angle deviation may result from spindle runout, eccentric tool installation or a worn flange. Check the machine spindle and clamping condition before determining whether the cutter needs adjustment or replacement.
A6: Yes. A worn PCD bevel cutter can be returned for professional regrinding. Proper regrinding can restore its cutting performance and help reduce overall tool procurement costs.
