Drill bit FANAR HSS cylindrical 3.4 mm for metal, model W2-103811-0340

FANAR HSS cylindrical drill bit 3.4 mm is a machining tool designed for drilling metal. Manufactured from high-speed steel (HSS), this straight-shank twist drill delivers wear resistance and dimensional stability appropriate for routine metalworking operations. It is intended for use with handheld drills and drill presses to create reliable, accurately sized holes in steel, iron and a range of other ferrous and non‑ferrous metals in workshop and maintenance environments.

Advantages

The high-speed steel construction offers good hardness at cutting temperatures, helping maintain cutting edge integrity and extending service life during general-purpose drilling. The cylindrical shank provides secure clamping in standard drill chucks, while the 3.4 mm diameter delivers consistent hole size for precision tasks. The drill geometry is suited to a variety of metals, balancing cutting performance and chip evacuation for efficient operation.

Suitable for

• Drilling holes in steel and iron components
• Creating pilot and through-holes in non-ferrous metals such as aluminum and brass
• Workshop maintenance and repair tasks using handheld drills or drill presses
• Fabrication and light to medium metalworking operations

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight shank) suitable for standard chucks
• Diameter: 3.4 mm
• Intended use: drilling in ferrous and non-ferrous metals

How to use

Secure the drill bit in a properly tightened drill chuck, ensuring the shank is fully seated and concentric. Select a suitable spindle speed for the workpiece material—lower speeds for harder steels, higher speeds for softer non-ferrous metals—and apply steady feed pressure to avoid excessive heat build-up. Use cutting fluid or lubricant when drilling steel and other hard metals to improve chip evacuation and reduce wear. After drilling, clear chips from the hole and inspect the drill bit for wear or damage before repeated use.

Usage recommendations

For best results, match drill speed and lubrication to the specific metal being worked: use slower speeds and cutting fluid for hardened steels and faster speeds for aluminum and brass. Replace the bit when consistent burrs, increased thrust force or poor hole quality indicate wear.
