Solid Carbide Drill Bit FANAR X-DRILL DIN 6537, diameter 5.80 mm, 5xD, HA6 VHM, AT coating

Solid carbide drill bit FANAR X-DRILL DIN 6537 with a 5.80 mm cutting diameter and a 5xD length ratio, manufactured in HA6 VHM grade and finished with an AT (anti-friction) coating. This tool is engineered for precise through and blind hole drilling in metallic materials, delivering consistent hole quality in high-speed machining and CNC operations. The DIN 6537 shank ensures secure clamping in straight-shank toolholders and reduces runout for repeatable accuracy.

Advantages

The FANAR X-DRILL combines a solid carbide substrate with a wear-resistant AT coating to extend tool life and reduce built-up edge during interrupted or continuous cuts. Its 5xD geometry balances reach and rigidity for clean chip formation and evacuation while maintaining concentricity. The HA6 VHM grade provides a good compromise between hardness and toughness, making the drill suitable for a range of metallic workpiece materials under high-speed conditions.

Suitable for

• Through and blind hole drilling in steels and non-ferrous metals
• CNC machining centers and high-speed drilling operations
• Batch production requiring repeatable hole diameters and surface finish
• Applications where reduced friction and improved chip flow are required

When it may not be suitable

This solid carbide, 5xD drill is not intended for heavy interrupted cuts in highly abrasive cast iron or extremely hard materials where a more robust grade or special geometry would be required. For very deep holes beyond the 5xD ratio or for extreme vibration-prone setups, alternative long-reach or indexable tooling may be more appropriate.

Key specifications

• Cutting diameter: 5.80 mm
• Length ratio: 5xD (overall length suited to five times the diameter)
• Material: solid carbide (VHM)
• Grade: HA6
• Coating: AT (anti-friction)
• Standard: DIN 6537 straight shank
• Intended use: through and blind hole drilling in metals

How to use

Mount the drill securely in a straight-shank holder compatible with DIN 6537 and verify runout is within acceptable limits before machining. Use appropriate cutting speeds and feeds for the workpiece material — start with moderate speeds and increase while monitoring wear and hole quality. Provide adequate coolant or cutting fluid to aid chip evacuation and reduce heat at the cutting edge; for dry drilling, ensure the AT coating and grade are suitable for the material. Retract periodically on deep or long holes to clear chips and avoid clogging.

What to consider before purchase

• Confirm compatibility with your machine’s holder and spindle (DIN 6537 straight shank)
• Ensure the 5xD length ratio meets the depth requirements of your applications
• Match drill grade and coating (HA6 VHM with AT) to the target workpiece material
• Check required surface finish and tolerance to verify this tool meets production needs

Usage recommendations

Use recommended cutting parameters from material-specific tooling charts, verify coolant flow for consistent chip removal, and replace the drill when wear affects hole diameter or surface finish to maintain repeatable accuracy in CNC production.
