FAQs

Common Questions About Diamond Router Bits

Which diamond router bits work best for granite countertops?

For granite countertops, sintered diamond router bits provide the best results. They handle granite's hardness without chipping and last significantly longer than brazed alternatives. Choose coarser grits (60-80) for rough shaping and finer grits (120-150) for finishing edges.

How can I prevent chipping when cutting granite?

Use proper feed rates, maintain consistent pressure, and ensure adequate cooling. Diamond router bits perform best at 2000-3000 RPM for granite. Always use flood cooling or continuous mist systems to prevent overheating and extend tool life.

What's the difference between sintered and brazed diamond bits?

Sintered diamond tools use chemical and mechanical bonding for harder materials, while brazed tools offer higher diamond exposure for softer materials. Sintered bits excel with granite and engineered stone, providing longer life but slower cutting. Brazed bits cut faster in marble and limestone with superior surface finish.

Can diamond router bits be resharpened?

Professional diamond router bit resharpening services are available for sintered and some brazed types. However, the long lifespan often makes replacement more cost-effective than resharpening. Resin bond bits typically aren't resharpened due to their bonding structure, but their lower initial cost offsets this limitation.

How do I choose the right diamond grit for my application?

Diamond grit selection depends on your material and desired finish quality. Coarse grits (40-80 mesh) provide aggressive material removal for rough shaping, while fine grits (120-220 mesh) deliver smooth finishes. Medium grits (80-120 mesh) offer balanced performance for general-purpose applications across various stone materials.Optimal speeds range from 2000-4000 RPM depending on bit size and material. Smaller diameter bits can run at higher speeds, while larger bits require lower RPMs for proper cutting. Always use flood cooling or mist systems to prevent overheating and maximize tool life.

Are custom sizes available for special applications?

Yes, DINOSAW provides custom diamond router bits with tailored dimensions, grit sizes, and bonding types for specific applications. Custom profiles, shank sizes, and diamond concentrations can be manufactured to meet unique project requirements. Lead times vary based on complexity, typically 2-4 weeks for standard modifications.

How do I choose between sintered, brazed, and resin bond processes?

Process selection depends on your material hardness and application requirements. Sintered diamond bits excel with granite and engineered stone, providing maximum durability for production environments. Brazed bits offer superior surface finishes on marble and limestone with faster cutting speeds. Resin bond bits deliver precision control for delicate materials like ceramics and glass. DINOSAW provides free consultation to help determine the optimal process for your specific application.

Do I need special safety equipment for angle grinder use?

Yes, safety guard plates are mandatory when using diamond router bits with angle grinders. DINOSAW provides high-strength safety guards designed specifically for diamond router bit applications. These guards protect against debris and ensure compliance with industrial safety standards. Professional installation and proper training are recommended for safe operation.
