Drill bit FANAR HSS cylindrical for metal 6.2 mm (W2-101811-0620)

FANAR HSS cylindrical drill bit for metal, 6.2 mm diameter, is a straight-shank high-speed steel twist drill designed for cutting and drilling metallic materials. Intended for use in hand drills and drill presses, the bit is suitable for creating through-holes in workshop and industrial metalworking applications where a precise 6.2 mm hole is required. The HSS material provides a balance of hardness and toughness for general-purpose drilling in steels, non-ferrous metals and some alloys.

Advantages

The high-speed steel construction ensures durability and heat resistance during continuous drilling operations. The cylindrical (straight) shank provides a secure fit in standard three-jaw chucks and drill holders, reducing wobble and improving concentricity. The twist-flute geometry evacuates chips effectively during through-hole drilling, helping to maintain drill life and hole quality. The 6.2 mm diameter gives a precise nominal size for fitment and clearance tasks where a slightly oversized 6 mm hole is required.

Suitable for

• Creating through-holes in mild steel, stainless steel, aluminium and non-ferrous alloys
• Workshop drilling with hand-held electric drills and drill presses
• Metal fabrication, assembly and maintenance tasks requiring a 6.2 mm hole

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Diameter: 6.2 mm nominal cutting diameter
• Flute style: twist flute for chip evacuation
• Primary use: drilling metallic materials and alloys

How to use

Secure the drill bit in the drill chuck so the shank is held firmly and runout is minimised. Mark the drilling position and, if necessary, use a centre punch to prevent walking on smooth surfaces. Select an appropriate spindle speed and cutting fluid for the metal being drilled — lower speeds for harder steels, higher speeds for softer non-ferrous metals. Apply steady, moderate feed pressure and withdraw periodically on through-holes to clear chips. After use, clean chips from the flutes and store the bit in a dry place to avoid corrosion.

Usage recommendations

For best results, match spindle speed and lubricant to the workpiece material: use cutting oil for steel and higher speeds with light lubrication for aluminium. Replace the bit when wear or chipping reduces hole quality; sharpening should be performed by a qualified tool grinder to restore correct point geometry.
