R2.5x10x20x120L Brazed Diamond Stone Bit CNC Guide
The R2.5x10x20x120L brazed diamond stone bit is a long-reach CNC grinding and profiling tool for granite, marble, engineered stone and compatible hard materials. Its R2.5 radius, 10 mm diameter, 20 mm working section and 120 mm overall length support edge details and recessed features when machine rigidity, cooling and dust or slurry control are suitable.
Stone Machining Applications
- Radius edge profiling on granite and marble
- Detail grinding in deep or recessed stone features
- Engineered-stone shaping with compatible cooling
- CNC finishing after rough cutting or stock removal
CNC Setup, Cooling and Feed
Use the shortest practical extension, verify tool runout and clamp the stone securely. Begin with parameters recommended by the diamond-tool and material suppliers. Provide the required water cooling or dust extraction and never allow the cutting zone to overheat. Observe sound, spindle load, vibration, slurry or dust condition and surface finish. These practices apply to CNC numerical control stone routers and machining centers.
JEEFOO Quality and Guangzhou Supply
JEEFOO supplies diamond and carbide CNC tools from Guangzhou, China. Each R2.5x10x20x120L brazed diamond stone bit should be checked for radius, diameter, working length, overall length, braze quality, diamond condition and model identification before packaging. Visit the JEEFOO CNC tools homepage for related stone tooling and company contact details.
Inspection and Safe Operation
Inspect the diamond surface and brazed joint for impact damage, cracks, separation or heavy wear. Verify the holder is clean and the tool is securely installed. Use guarding, eye and respiratory protection, and controls appropriate for silica-containing dust or slurry. Stop immediately if vibration, unusual noise, overheating or bond damage appears.
R2.5x10x20x120L Brazed Diamond Stone Bit FAQ
What does R2.5 identify?
R2.5 specifies the nominal 2.5 mm radius profile. Confirm the final drawing and finished-part tolerance before production.
Why is cooling important?
Cooling controls heat at the diamond and brazed interface, helps remove debris and supports consistent stone finish. Follow the tool and machine supplier’s requirements.
