Drill bit Tvardy HSS for metal 9.00 mm (model T02090)

Tvardy HSS drill bit for metal, 9.00 mm diameter, is a high-speed steel twist drill intended for creating clean, accurate holes in a variety of ferrous and non-ferrous metal materials. Designed for general metalworking tasks, this 9.00 mm drill bit fits standard drill chucks and can be used with both handheld and stationary drills. Its geometry and HSS material provide a balance of hardness and toughness for reliable cutting performance in workshop and repair settings.

Advantages

The HSS construction delivers good wear resistance and heat tolerance compared with carbon steel bits, enabling sustained drilling speed in metal. The twist-flute design promotes efficient chip evacuation to reduce clogging and improve hole quality. The 9.00 mm diameter is a common size for mechanical assemblies and repair work, offering predictable fit for bolts, dowels, and clearance holes. Compatibility with standard chucks makes the bit easy to install and use across a wide range of drills.

Suitable for

• Drilling clearance and pilot holes in steel and aluminium
• Workshop maintenance and repair tasks
• General metal fabrication and assembly work
• Portable drilling with handheld drills or stationary drill presses

Key specifications

• Material: High-speed steel (HSS)
• Type: Twist drill bit
• Diameter: 9.00 mm
• Intended use: Metal drilling (ferrous and non-ferrous)
• Shank compatibility: Standard round shank for common drill chucks

How to use

Secure the drill bit in the drill chuck and ensure it is tightly clamped before starting. Mark the drilling position and, if necessary, use a center punch to prevent walking. Select an appropriate drilling speed and feed rate for the metal being drilled; lower speeds are generally advisable for harder steels. Apply steady pressure and allow the bit to cut without excessive force. Use cutting fluid for improved cooling and chip removal when drilling harder materials or during prolonged operations. After drilling, retract the bit while the drill is running briefly to clear chips, then stop the machine before inspecting the hole.

Usage recommendations

For best results, use appropriate cutting fluid and moderate speed settings when drilling steel; increase speed slightly for softer non-ferrous metals. Regularly inspect the bit for wear and re-sharpen or replace when edge dulling reduces performance. Store the bit in a dry place to prevent corrosion.
