FANAR solid carbide drill DIN 6537 L WK5 9 mm, VHM TiAlN, 103–61 mm

FANAR solid carbide drill DIN 6537 L WK5 9 mm with VHM TiAlN coating is a long-shank precision drill designed for demanding metalworking tasks. The tool features a 9 mm cutting diameter and a long shank profile (length range 103–61 mm) to reach deeper or hard-to-access holes while maintaining rigidity. The TiAlN surface treatment increases hardness and heat resistance, reducing wear and extending tool life in high-speed and high-temperature drilling operations on steels and common alloys.

Advantages

The solid carbide construction provides high stiffness and dimensional stability for accurate hole geometry. The TiAlN coating improves thermal resistance and reduces built-up edge, which helps maintain cutting performance under elevated temperatures. The long shank design allows greater reach without sacrificing concentricity, and the DIN 6537 L WK5 geometry is optimized for consistent chip evacuation and stable cutting action in a range of machining conditions.

Suitable for

• Drilling through steels and alloy materials
• Applications requiring long-reach drilling or access to recessed features
• High-speed drilling where thermal resistance is important
• Precision machining where hole accuracy and surface finish matter

Key specifications

• Cutting diameter: 9 mm
• Shank/overall length range: long shank configuration (lengths in range 103–61 mm)
• Material: solid carbide
• Coating: TiAlN (titanium aluminum nitride) for enhanced heat and wear resistance
• Standard/geometry: DIN 6537 L WK5 optimized for chip control and stability

How to use

Mount the drill in a suitable chuck or toolholder that matches the shank and machine spindle requirements, ensuring secure clamping and runout within recommended limits. Use appropriate spindle speed and feed for the workpiece material and 9 mm diameter tool, adjusting coolant or lubrication according to material and coating compatibility. Apply controlled pecking or retract cycles when drilling deep holes to assist chip evacuation and prevent clogging. Inspect the tool regularly for wear and re-evaluate cutting parameters if hole quality degrades.

Usage recommendations

For best results, select cutting speeds and feed rates suited to the workpiece material, keep coolant directed at the cutting zone when machining steels, and use intermittent pecking for deep holes to improve chip removal and tool life. Replace the drill when wear affects hole tolerance or surface finish.
