Drill bit FANAR HSS cylindrical 4.7 mm model W2-101811-0470

FANAR HSS cylindrical drill bit with a 4.7 mm diameter, model W2-101811-0470, is a high-speed steel twist drill designed for general metalworking and workshop tasks. The straight shank fits standard chucks and holders, allowing use in handheld drills and drill presses. The HSS material provides wear resistance and heat tolerance suitable for drilling a variety of ferrous and non-ferrous metals as well as common workshop materials.

Advantages

This 4.7 mm HSS cylindrical drill bit offers consistent hole quality and dimensional accuracy for routine drilling operations. The high-speed steel construction balances hardness and toughness to reduce premature wear while maintaining cutting edge performance at elevated temperatures. The straight shank design ensures compatibility with a wide range of chucks and collets, simplifying tool changes and reducing setup time.

Suitable for

• Drilling holes in mild steel and stainless steel (appropriate cutting speeds and lubrication recommended)
• General workshop and fabrication tasks requiring 4.7 mm holes
• Use in handheld electric drills, drill presses and pillar drills with standard chucks
• Repair, maintenance and assembly operations in mechanical and metalworking environments

Key specifications

• Material: High-speed steel (HSS)
• Type: Cylindrical twist drill with straight shank
• Nominal diameter: 4.7 mm
• Intended use: Metalworking and general-purpose drilling
• Shank style: Straight shank compatible with standard chucks and holders

How to use

Secure the drill bit in a compatible chuck or collet, ensuring proper centering and clamping to avoid runout. Select a cutting speed and feed appropriate for the workpiece material; for harder metals use lower speed and steady feed. Apply cutting fluid or lubricant when drilling ferrous metals to reduce heat and extend tool life. Start with a pilot hole if high positional accuracy is required, and clear chips regularly to prevent clogging and heat buildup.

Usage recommendations

For best results when drilling metals, use moderate cutting speeds, steady feed, and suitable cutting lubricant. Inspect the drill bit for wear and replace when the cutting edges blunt or chip to maintain hole quality and reduce workpiece damage.
