Drill bit FANAR HSS cylindrical 8.7 mm, metal drilling, solid shank (W2-101811-0870)

FANAR HSS cylindrical drill bit Ø8.7 mm is designed for drilling metal in workshop and maintenance environments. Manufactured from high-speed steel (HSS), this solid-shank twist drill retains cutting performance at elevated temperatures and resists wear during repeated use. The cylindrical shank allows secure clamping in standard drill chucks and bench drills, making the bit suitable for routine drilling of steel and non-ferrous metals in general metalworking and prototype tasks.

Advantages

The high-speed steel construction provides wear resistance and reliable cutting performance when drilling through mild and alloyed steels or non-ferrous materials. The solid, cylindrical shank ensures stable mounting in common chucks and drill presses, reducing runout and improving hole accuracy. Its Ø8.7 mm diameter meets specific machining needs where intermediate hole sizes are required, combining versatility with consistent drilling quality.

Suitable for

• Drilling holes in mild steel and alloyed steels
• Working with non-ferrous metals such as aluminum, brass and copper
• Workshop maintenance and repair tasks
• Prototype and small-batch metal fabrication
• Use in benchtop drills and handheld drill chucks

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical (solid shank) for standard chucks
• Diameter: 8.7 mm
• Application: Metal drilling (steel and non-ferrous metals)
• Geometry: Twist drill profile for general-purpose drilling

How to use

Select a suitable drill speed and appropriate cutting fluid for the material being machined to extend tool life and improve hole finish. Secure the cylindrical shank firmly in the drill chuck or press, ensuring minimal runout. Start drilling with light feed to establish the hole, then increase feed steadily while maintaining coolant application. Clear chips periodically to avoid clogging and heat buildup. After drilling, deburr the hole as necessary.

Usage recommendations

For carbon and low-alloy steels use moderate speeds with cutting oil; for aluminum and other non-ferrous metals, slightly higher speeds and light lubrication are effective. Inspect the bit for wear and replace if the cutting edges are rounded or if drilling requires excessive force.
