Drill bit for metal FANAR HSS cylindrical 10.3 mm W2-101811-1030

The FANAR HSS cylindrical drill bit with a 10.3 mm diameter is designed for drilling metal and producing precise round holes. Manufactured from high-speed steel (HSS), this solid twist drill delivers wear resistance and stable cutting performance when used in hand drills or drill presses. The cylindrical shank ensures secure clamping in standard chucks and supports applications in metalworking, maintenance and fabrication where accuracy and reliable tool life are required.

Advantages

This HSS drill bit offers a balance of hardness and toughness suitable for mild to medium-hard metals. Its high-speed steel construction provides improved wear resistance compared with carbon steel, while the standard geometry promotes predictable chip evacuation and consistent hole quality. The cylindrical shank is compatible with most chucks, enabling straightforward installation and replacement. Overall, the design supports repeated, accurate drilling with minimal need for specialized holders.

Suitable for

• Drilling holes in mild steel and medium-hard alloys
• General metalworking and fabrication tasks
• Maintenance and repair operations using hand drills or drill presses
• Creating precise round holes for assembly and mounting

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 10.3 mm
• Shank type: Cylindrical
• Intended material: Mild and medium-hard metals
• Tool type: Twist drill for metal

How to use

Select an appropriate drilling speed and apply steady feed to avoid overheating; use cutting fluid when working with metals to extend tool life and improve surface finish. Secure the workpiece in a vise or fixture and clamp the drill bit firmly in the chuck. Start with a pilot mark or center punch to prevent walking, then drill with controlled pressure, retracting occasionally to clear chips if necessary. After use, clean the bit of chips and cutting fluid and store it in a protective holder to prevent damage.

Usage recommendations

For best results, match drill speed to material hardness: lower speeds for harder alloys and higher speeds for softer steels. Use appropriate cutting lubricant for ferrous metals and monitor drill bit temperature to avoid excessive wear or loss of hardness.
