Drill Bit FANAR HSS Cylindrical 4.9 mm for Metal, MPN W2-101811-0490

FANAR HSS cylindrical drill bit with a 4.9 mm diameter, designed specifically for drilling metal. Manufactured from high-speed steel (HSS), the bit provides a balance of hardness and toughness for cutting through steel, cast iron and non-ferrous metals. The cylindrical shank fits standard drill chucks and is suitable for both hand-held drills and drill presses, enabling use in workshop and industrial settings for through and blind holes.

Advantages

The HSS material offers wear resistance and sustained cutting performance at moderate cutting speeds. The 4.9 mm diameter provides a precise hole size for fitting small fasteners or pilot holes. The cylindrical shank ensures secure clamping in standard chucks, reducing runout and improving accuracy. The geometry of the cutting edges and point angle is optimized for metalworking to reduce burr formation and improve chip evacuation when used with appropriate coolant or lubricant.

Suitable for

• Drilling holes in mild and medium-strength steel
• Creating holes in cast iron and non-ferrous metals such as aluminum and brass
• Workshop tasks with hand drills and bench or pillar drill presses
• Producing through holes and blind holes for assembly and fabrication

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical (round) shank for standard chucks
• Drill diameter: 4.9 mm
• Intended use: Metal drilling (steel, iron, non-ferrous metals)
• Suitable for: Hand drills and drill presses

How to use

Secure the drill bit in the chuck, ensuring it is straight and tightened to minimize runout. Select appropriate spindle speed for the material being machined — lower speeds for harder steels, higher speeds for softer non-ferrous metals — and apply cutting fluid or lubricant when drilling steels to extend tool life and improve chip removal. Start with a center punch for accurate hole location if necessary, then apply steady, even feed pressure without forcing the bit. Clear chips periodically during drilling to prevent clogging and overheating.

Usage recommendations

For best performance, use cutting fluid when drilling steels and set drill speeds according to material hardness. Replace the bit if it shows signs of excessive wear, chipping, or reduced cutting performance to maintain hole quality and operator safety.
