Drill bits Proline Urbis HSS 3.0 mm, set of 3

Proline Urbis HSS drill bits 3.0 mm are designed for metal drilling and come as a set of three. Each bit features a 135° split-point angle with adjustable relief for improved centering and reduced walking. Made from high-speed steel (HSS) for durability in metalworking, the bits have a working length of 33 mm and a total length of 61 mm.

Advantages

The 135° split-point angle with slope adjustment ensures better precision and faster penetration into metal surfaces. HSS construction provides wear resistance and sustained cutting ability at higher temperatures compared to standard carbon steel. The 3.0 mm diameter with defined working and total lengths makes these bits suitable for controlled, repeatable drilling depths.

Suitable for

• Drilling steel and non-ferrous metals
• Precision metalworking and maintenance tasks
• Workshop and professional use where small-diameter holes are required

How to use

Mark the drilling point and secure the workpiece in a vice or clamp to prevent movement. Select appropriate drilling speed for the metal type and use cutting fluid for improved cooling and tool life. Align the drill perpendicular to the surface and apply steady pressure; allow the bit to cut without excessive force. Clear swarf periodically and replace the bit when wear degrades performance.

Usage recommendations

Use lower speeds and adequate lubrication when drilling hardened steels. For optimal results, inspect bits before use and store them dry to prevent corrosion.
