Drill bit FANAR W9-614X13-0680, solid carbide VHM, diameter 6.80 mm, length 53/91 mm, 5xD, HA8, X-DRILL DIN 6537

Solid carbide drill bit FANAR W9-614X13-0680 is a precision cutting tool with a 6.80 mm diameter, designed for deep-hole drilling in metalworking and CNC applications. The tool follows the DIN 6537 X-DRILL geometry and a 5xD length ratio, providing repeatable chip evacuation and stable axial guidance. Available with overall and working lengths of 91 mm and 53 mm respectively, this VHM (solid carbide) drill is manufactured to HA8 specification for consistent edge geometry and improved wear resistance in demanding production environments.

Advantages

This solid carbide drill offers high rigidity and dimensional stability, reducing deflection during high-speed or heavy-feed operations. The DIN 6537 X-DRILL geometry improves chip control and coolant flow for extended tool life. The 5xD length ratio balances reach and stiffness, enabling deeper drilling with reliable concentricity. HA8-grade manufacturing ensures uniform cutting edge quality and predictable performance across batches.

Suitable for

• Precision CNC machining of steel alloys and non-ferrous metals
• Deep-hole drilling where 5x diameter penetration is required
• Production environments requiring consistent tool performance and repeatability
• Operations that benefit from solid carbide rigidity and wear resistance

How to use

Select spindle speed and feed rate appropriate for the workpiece material and the 6.80 mm carbide geometry, using manufacturer’s cutting data where available. Secure the drill in a rigid, balanced tool holder and ensure proper axial alignment. Use through-tool or external coolant directed to the cutting zone to improve chip evacuation and reduce temperature. For deep holes, pecking cycles or periodic retraction may be used to clear chips and maintain hole quality. Inspect the cutting edges and flute condition regularly and replace the tool when wear affects accuracy or surface finish.

Usage recommendations

For best results, pre-drill pilot holes when working in very hard or highly abrasive materials, maintain stable clamping of the workpiece, and use coolant suitable for carbide tools. Monitor spindle runout and tool holder condition to preserve concentricity and extend service life.
