Custom Composite Cutting Tools for CFRP & GFRP

Custom Composite Cutting Tools for CFRP, GFRP & Advanced Materials

Machining advanced composite materials requires specialized cutting tools capable of handling abrasive fibers, varying material densities and complex layered structures.

GDP Tooling provides custom composite cutting tools, including polycrystalline diamond (PCD) and carbide tooling, engineered for CNC machining of carbon fiber, fiberglass, honeycomb, syntactic foam and other difficult-to-machine materials.

Our tooling solutions are developed around the specific workpiece, machine capabilities, cutting operation and production requirements.

CFRP Cutting Tools for Carbon Fiber Composites

Carbon fiber reinforced polymer (CFRP) is highly abrasive and can cause rapid cutting-edge wear, fiber pullout and delamination when machined with unsuitable tooling.

Custom CFRP cutting tools can be designed for:

• CNC routing and contouring
• Edge trimming and profiling
• Drilling and hole preparation
• Grooving and pocketing
• Specialized cutting and finishing operations

Depending on the application, PCD diamond or carbide cutting geometries can help improve edge quality, reduce secondary finishing and maintain consistent machining performance.

GFRP and Fiberglass Cutting Tools

Glass fiber reinforced polymer (GFRP) and fiberglass composites present similar challenges, including abrasive wear, fiber fraying, breakout and inconsistent edge finishes.

GDP Tooling develops custom fiberglass cutting tools for trimming, routing, drilling and profiling applications.

Tool geometry, cutting-edge material and machining parameters are selected according to the fiber reinforcement, resin system, material thickness and required finish.

Cutting Tools for Honeycomb, Syntactic Foam & Sandwich Panels

Advanced composite structures often combine materials with significantly different machining characteristics.

Applications include:

• Nomex and other honeycomb core materials
• Structural and syntactic foams
• Carbon fiber and fiberglass sandwich panels
• Aluminum-faced composite panels
• G10, phenolics and glass-filled materials
• Multi-layer and hybrid composite structures

Custom cutting tools can be engineered to accommodate the different layers within a single workpiece, helping control cutting forces, minimize damage and improve finished-part quality.

Custom PCD and Carbide Tooling for Composite Machining

PCD diamond cutting tools offer excellent wear resistance and can provide extended tool life in suitable high-volume composite machining applications.

However, PCD is not always the most appropriate choice. Depending on material construction, tool geometry, production volume and machining conditions, solid carbide or carbide-tipped tooling may offer a more practical solution.

GDP Tooling evaluates each application to determine the appropriate cutting material and geometry rather than relying on a one-size-fits-all approach.

Engineered Composite Cutting Solutions

Successful composite machining depends on more than the cutting tool alone.

Our application review considers material composition, laminate and core construction, machine type, spindle speed, feed rate, cutting depth, toolholding and required finished-edge quality.

Custom tools can also combine multiple cutting operations where practical, helping reduce tool changes, machining time and secondary processing.
