Drill bit set Proline Urbis 3.5 mm — HSS metal, 3 pcs

Proline Urbis HSS metal drill bit set, diameter 3.5 mm, three pieces. Designed for drilling metals and similar materials, these bits are made from high-speed steel (HSS) and feature a 135° split-point geometry with adjustable margin to improve centring and reduce walking. Working length is 39 mm and overall length is 70 mm, providing a compact option for workshop, professional or DIY metalworking tasks.

Advantages

The HSS construction ensures good wear resistance and reliable cutting performance on a variety of metals. The 135° split-point with chamfer adjustment enhances penetration and reduces the need for pilot holes, while the consistent 3.5 mm diameter across the three-piece set provides repeatable hole sizing for maintenance and assembly work.

How to use

Secure the drill bit in the chuck of a drill or drill press, ensuring firm clamping without overtightening. Mark the drilling point on the workpiece; for thin or slippery surfaces, use a centre punch to prevent walking. Operate at an appropriate speed for the metal being drilled and apply steady, moderate pressure. Use cutting fluid or coolant when drilling harder steels to extend tool life and improve chip evacuation. Withdraw the bit periodically to clear chips and avoid overheating.

Usage recommendations

For best results, match drill speed and cutting fluid to the metal type, clamp the workpiece securely, and replace worn bits to maintain hole quality and safe operation.
