Drill bit FANAR HSS cylindrical 4.5 mm for metal, model W2-103811-0450

Cylindrical HSS drill bit FANAR 4.5 mm is designed for accurate drilling in metal. Made from high-speed steel (HSS), the 4.5 mm diameter flute and straight cylindrical shank ensure reliable cutting performance and compatibility with standard drill chucks. The bit is intended for workshop and industrial metalworking where straight, precise holes in steel, iron and non‑ferrous metals are required.

Advantages

The high-speed steel construction provides a balance of hardness and toughness for good wear resistance and long tool life under typical drilling conditions. The cylindrical shank allows quick mounting in common chucks and provides stable rotation for consistent hole quality. The 4.5 mm diameter gives a common size for through-holes, pilot holes and fastening preparations in a range of metalworking tasks.

Suitable for

• Drilling holes in mild and alloy steels
• Piercing iron and cast materials
• Working with non-ferrous metals such as aluminium, brass and copper
• Creating pilot holes for screws, rivets and fasteners
• Workshop and light industrial metal fabrication

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 4.5 mm
• Shank type: cylindrical (straight)
• Intended material: metal (steel, iron, non-ferrous metals)
• Typical use: drilling and pilot-hole making

How to use

Select an appropriate drill press or handheld drill with a compatible chuck and secure the workpiece. Mark the drilling position and, if necessary, use a center punch to avoid wandering. Fit the FANAR 4.5 mm HSS bit into the chuck and tighten firmly. Use suitable cutting speed for the metal being drilled, apply steady feed pressure, and use cutting fluid when drilling harder steels to reduce heat and prolong bit life. Clear chips regularly and finish the hole with reduced feed or a backing plate if required to prevent burrs.

Usage recommendations

Apply cutting fluid when drilling hardened or stainless steels, moderate speeds for general steel and higher speeds for softer non‑ferrous metals. Replace the bit when wear or chipping affects hole accuracy, and store in a dry place to avoid corrosion.
