Irwin metal drill bit HSS Titanium 8.5 mm for drilling steel and metal alloys

Irwin metal drill bit HSS Titanium 8.5 mm is a high-speed steel drill designed for drilling steel and a wide range of metal alloys. The bit features a titanium coating that reduces friction and increases wear resistance, extending service life compared with uncoated HSS bits. It is suitable for use in hand drills and drill presses and delivers precise holes and stable cutting performance for workshop, construction and repair tasks.

Advantages

The titanium coating improves heat dissipation and decreases surface friction, which helps maintain cutting edge sharpness and extend the bit's lifetime. Manufactured from high-speed steel, the bit provides reliable hardness and toughness for drilling into various ferrous and non-ferrous metals. Its standard 8.5 mm diameter offers a balance between drilling speed and hole accuracy, while compatibility with common chucks ensures easy mounting and stable operation.

Suitable for

• Drilling holes in structural steel and sheet metal
• Metal fabrication and workshop tasks
• Maintenance, repair and retrofit work
• Use with electric hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Coating: titanium
• Diameter: 8.5 mm
• Suitable materials: steel and various metal alloys
• Intended tools: hand drills and drill presses

How to use

Secure the drill bit in a properly tightened chuck and set an appropriate drilling speed for the workpiece material; lower speeds are recommended for harder steels. Use cutting fluid or coolant when drilling thicker or harder metals to reduce heat build-up and prolong bit life. Apply steady, moderate pressure and allow the bit to cut without excessive force; withdraw periodically to clear chips and prevent clogging.

Usage recommendations

For best results, start with a pilot hole when drilling large or thick sections, maintain a steady feed rate, and replace or re-sharpen the bit when wear reduces cutting performance. Store the bit in a dry place to avoid corrosion and handle with care to preserve the titanium coating.
