Drill bit FANAR WIERTLO WEGLIK Ø10.00 mm, length 47/89 mm, 3xD, VHM, DIN 6537

FANAR WIERTLO WEGLIK solid carbide drill bit with a 10.00 mm cutting diameter and two-part length specification 47/89 mm is manufactured to DIN 6537 and provides a 3xD working length ratio. The VHM (solid carbide) construction delivers high rigidity and wear resistance, suitable for precise metal drilling and industrial machining where dimensional stability is required. The geometry and tolerance levels are engineered for consistent hole quality in through-holes and deeper drilling operations.

Advantages

The solid carbide body offers improved resistance to abrasion and thermal deformation compared with high-speed steel alternatives, maintaining cutting edge sharpness over extended production runs. Compliance with DIN 6537 ensures standardized shank and flute geometry for reliable clamping and repeatable performance in machine spindles. The 3xD length ratio balances reach and rigidity, reducing deflection in deeper holes while preserving chip evacuation and hole accuracy.

Suitable for

• Precision drilling of steel and alloy components
• Through-holes and moderately deep holes up to three times the diameter
• High-volume production and CNC machining
• Applications requiring consistent hole diameter and surface finish

Key specifications

• Cutting diameter: 10.00 mm
• Overall/working length (two-part): 47/89 mm
• Working length ratio: 3×D
• Material: solid carbide (VHM)
• Standard: DIN 6537
• Intended use: metal drilling, through and deep hole machining

How to use

Secure the drill bit in a compatible chuck or toolholder designed for DIN 6537 shanks, ensuring proper clamping to minimize runout. Select cutting speeds and feeds appropriate for the workpiece material and the carbide grade; reduce speed and increase feed when drilling harder alloys. Use suitable coolant or lubricants to control heat generation and improve chip evacuation. When drilling to full depth, peck drilling or periodic retraction can help prevent chip packing and maintain hole quality.

Usage recommendations

For best results, match cutting parameters to the specific workpiece material, maintain correct tool runout below machine and holder tolerances, and inspect drill condition periodically. Replace the drill when wear affects hole tolerance or surface finish to preserve part quality and avoid rework.
