Drill bit FANAR HSS cylindrical 4.4 mm for metal, model W2-101811-0440

FANAR HSS cylindrical drill bit 4.4 mm is designed for drilling metal and general metalworking tasks. Manufactured from high-speed steel (HSS), the 4.4 mm cutting diameter provides a balance between precision and material removal rate for common workshop and maintenance operations. The straight cylindrical shank fits standard chucks and holders, enabling stable clamping and straightforward tool changes.

Advantages

The HSS material offers improved wear resistance and heat tolerance compared with carbon steel, allowing longer cutting life and sustained performance under elevated temperatures typical for metal drilling. The cylindrical shank ensures secure mounting in compatible chucks and holders and simplifies alignment. The 4.4 mm diameter is suitable for creating through-holes and pilot holes in a variety of ferrous and non-ferrous metals.

Suitable for

• Drilling through-holes in mild steel, iron and non-ferrous metals
• Creating pilot holes for tapping or larger drills
• Workshop maintenance and repair tasks
• Light to medium-duty metal fabrication

Key specifications

• Cutting material: high-speed steel (HSS)
• Cutting diameter: 4.4 mm
• Shank type: cylindrical (straight) shank suitable for standard chucks
• Application: metal drilling (ferrous and non-ferrous)

How to use

Select a drill press or handheld drill with a chuck that accepts a cylindrical shank and clamp the bit securely. Mark the drilling position and, if needed, center-punch to reduce walking. Use appropriate spindle speed and feed for the workpiece material—lower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply steady, even pressure and use cutting lubricant or coolant when drilling tougher alloys or when prolonged cutting generates heat. Withdraw the drill periodically to clear chips and prevent clogging.

Usage recommendations

For best results, match drill speed and feed to the material being cut and use cutting fluid when working with steel or hardened materials. Ensure the cylindrical shank is clean and free of burrs before clamping into the chuck. When creating pilot holes for tapping, select an appropriate pilot size and verify alignment to avoid thread damage.
