Drill bit Proline HSS 6.0 mm – straight shank, high-speed steel

Proline HSS 6.0 mm drill bit with a straight shank, designed for drilling metal. The bits are made from high-speed steel (HSS) and feature a 135° cutting angle with an adjustable relief angle for improved cutting performance. Diameter 6.0 mm, working length 57 mm, overall length 93 mm.

Advantages

The HSS construction provides durability and heat resistance during metal drilling. A 135° tip reduces walking and improves centering on metal surfaces, while the adjustable relief angle allows for finer control of cutting action. The straight shank fits standard chucks and offers stable mounting.

Suitable for

• Drilling through steel and other metals
• Workshop and maintenance tasks
• Use with hand drills and drill presses

How to use

Secure the drill bit in the chuck of a suitable drill or drill press, ensuring it is centered and tightened. Mark the drilling point on the metal workpiece and, if necessary, use a center punch to prevent wandering. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply steady pressure and use cutting fluid or coolant when drilling harder metals to extend bit life and improve cutting performance.

Usage recommendations

For best results when drilling metal, use a suitable cutting lubricant, moderate feed pressure, and appropriate drill speed for the material. Replace the bit if it becomes dull or damaged to maintain hole quality and safety.
