Drill bit FANAR 5.00 mm solid carbide, length 28/66 mm, 3xD, HA6, DIN 6537

Solid carbide drill bit FANAR 5.00 mm is designed for precision through and blind drilling in metalworking environments. The tool features a 5.00 mm cutting diameter, a working length of 28 mm and an overall length of 66 mm (28/66 mm format). Manufactured to DIN 6537 shank standard and held to HA6 tolerance, this drill bit offers high rigidity and consistent concentricity for use in milling machines, drill presses and CNC equipment.

Advantages

The solid carbide construction provides excellent wear resistance and edge retention compared with high-speed steel drills, enabling stable cutting at higher spindle speeds. The 3xD length-to-diameter ratio balances reach and stiffness, reducing vibration and improving hole quality. Compliance with DIN 6537 shank dimensions and HA6 tolerance ensures reliable clamping and reduced runout when used with standard tool holders and chucks.

Suitable for

• Precision drilling in steels, stainless steels and non-ferrous metals
• CNC machining and automated drilling operations
• Drill presses and milling machines requiring rigid tooling
• Applications where tool life and dimensional accuracy are important

Key specifications

• Cutting diameter: 5.00 mm
• Working length: 28 mm
• Overall length: 66 mm
• Length-to-diameter ratio: 3×D
• Material: solid carbide
• Tolerance: HA6
• Shank standard: DIN 6537

How to use

Secure the drill bit in a compatible holder or chuck that accepts DIN 6537 shanks and verify clamping to minimize runout. Select cutting speeds and feed rates appropriate to the workpiece material and use cutting fluid where required to extend tool life and improve surface finish. For best results with the 3×D geometry, use pecking or break-off cycles when drilling deep holes to evacuate chips and prevent clogging.

Usage recommendations

Monitor tool wear and replace the drill when chipping or excessive runout appears. Use appropriate coolant and adjust speeds for hardened materials; avoid excessive feed that may cause tool breakage. For demanding tolerances, inspect hole dimensions after machining and ream if necessary.
