Drill bit for metal FANAR HSS cylindrical 6.3 mm

FANAR cylindrical HSS drill bit with a 6.3 mm diameter is a solid high-speed steel cutting tool intended for drilling steel and a wide range of ferrous and non-ferrous metals. The straight cylindrical shank fits standard cylindrical collets and tool holders as well as common handheld drills, providing reliable concentricity. The fluted geometry and HSS material deliver a balance of cutting speed, wear resistance and toughness required for routine workshop, maintenance and fabrication operations.

Advantages

The HSS construction ensures heat resistance and edge retention during continuous drilling in metal, while the 6.3 mm size offers versatility for common hole sizes. The cylindrical shank simplifies mounting in collets and chucks without the need for reduced shanks or special adapters. Flute design promotes efficient chip evacuation, reducing clogging and helping to maintain hole accuracy over extended use.

Suitable for

• Drilling holes in mild and alloy steels
• Work with non-ferrous metals such as aluminum and copper
• Workshop and maintenance repairs
• Fabrication and assembly of metal components
• Handheld drilling and machine tool operations with cylindrical collets

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Diameter: 6.3 mm
• Tip/point: Standard twist drill geometry suitable for metal
• Suitable materials: Ferrous and non-ferrous metals

How to use

Secure the drill bit in a compatible cylindrical collet or drill chuck, ensuring the bit is held concentric and tightly. Select an appropriate spindle speed and feed rate for the metal being drilled—lower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply cutting fluid or lubricant when drilling steel to reduce heat and improve tool life. Use steady, controlled feed pressure to avoid walking or bending of the bit, and periodically withdraw the bit to clear chips if drilling deep holes.

Usage recommendations

For best results, match cutting speed and lubrication to the workpiece material: use moderate speeds and cutting oil for alloy and mild steels, and higher speeds with light lubrication for aluminum and other soft metals. Inspect the bit for wear before use and replace if the cutting edges are dulled or the tip is damaged to maintain hole quality and operator safety.
