Drill bit FANAR W9-614X13-0420 VHM carbide Ø4.20 mm, length 36/74 mm, 5xD, HA6, X-DRILL DIN 6537

Solid-carbide drill bit FANAR W9-614X13-0420 VHM is a precision tool with a cutting diameter of 4.20 mm, overall length 74 mm and working length 36 mm. Manufactured to DIN 6537 standard, this X-DRILL geometry tool is designed for drilling to a 5xD depth ratio with HA6 tolerance, offering high concentricity and repeatable hole accuracy for metalworking and industrial machining applications.

Advantages

The solid-carbide construction provides high rigidity and wear resistance compared to high-speed steel alternatives, maintaining sharpness over prolonged cycles. X-DRILL geometry improves chip evacuation and reduces cutting forces, while the HA6 tolerance ensures consistent diameter precision for tight-fit holes. Compliance with DIN 6537 indicates standardized flute and shank dimensions for compatibility with collets and tool holders.

Suitable for

• Precision drilling in steels and non-ferrous metals
• Production environments requiring repeatable hole quality
• Deep hole drilling up to 5×D in rigid setups
• Use in CNC machines, drilling centers, and toolroom equipment

How to use

Select appropriate spindle speed and feed rate according to material and tool manufacturer recommendations. Secure the drill in a suitable collet or tool holder that matches the shank and DIN 6537 dimensions. Ensure rigid workholding and minimal runout to take advantage of the HA6 tolerance. Use suitable cutting fluid or coolant for metal machining to improve tool life and chip evacuation. Monitor tool wear and replace the drill when surface finish or dimensional accuracy degrades.

Usage recommendations

For best results, pre-drill pilot holes when working in softer materials that may cause chip packing, and reduce pecking intervals for deep holes to maintain chip flow. Maintain spindle runout below recommended limits to preserve HA6 tolerance and hole accuracy.
