## Summary description

Solid carbide twist drill by FANAR, diameter 5.10 mm with overall/working lengths 28/66 mm and a 3xD flute length ratio. Manufactured to DIN 6537, featuring HA6 surface coating for increased wear resistance. Suitable for high-precision drilling in metals where carbide geometry and coating ensure longer tool life and consistent hole quality in production and workshop use.

## Long description

FANAR solid carbide twist drill bit Ø5.10 mm designed for precision metalworking. The drill has a 5.10 mm nominal diameter, overall length 66 mm and working length 28 mm, with a 3xD flute length ratio manufactured to DIN 6537 standards. The HA6 surface coating increases wear resistance and stability in repetitive drilling operations, while the solid carbide construction maintains cutting-edge rigidity and accuracy for production and workshop environments.
Advantages
The solid carbide body provides high stiffness and dimensional stability under cutting loads, reducing deflection and improving hole accuracy. HA6 coating offers enhanced surface hardness and reduced friction for longer tool life and more consistent performance when machining a variety of metals. Compliance with DIN 6537 ensures standardized geometry and shank dimensions for reliable clamping and interchangeability with compatible holders and machines.
Suitable for
 Precision through and blind hole drilling in steels, stainless steels and non-ferrous metals
 Production runs and CNC machining where repeatability and tool life are critical
 Workshop and toolroom use with indexable or solid toolholders meeting DIN 6537
Key specifications
 Diameter: 5.10 mm
 Overall length: 66 mm
 Working length (cutting length): 28 mm (3xD flute length ratio)
 Material: solid carbide
 Coating: HA6 surface treatment for improved wear resistance
 Standards: manufactured to DIN 6537 geometry
How to use
Secure the drill in a compatible holder or chuck that accepts DIN 6537 shank geometry and ensure concentric clamping. Select cutting speeds and feed rates appropriate to the workpiece material and carbide tooling; use coolant or cutting fluid when machining tougher steels or to prolong tool life. Begin with a pilot or center drill if required for positional accuracy, then drill at steady feed, clearing chips regularly to avoid clogging the flutes. Inspect hole quality and tool wear periodically and replace the drill when wear adversely affects dimensional accuracy.
Usage recommendations
For best results, use recommended cutting parameters for carbide tools and apply adequate coolant for stainless steels and heat-resistant alloys. Maintain correct clamping and alignment to minimize runout; replace the drill when wear signs appear to preserve hole accuracy and surface finish.
