## Summary description

Proline 77630 is a single metal drill bit with a 3 mm diameter and 190 mm overall length. Designed for drilling metal, it suits hand drills and drill presses for precision holes in thin to medium-thickness sheets and profiles. The pack contains one drill bit, useful for metalworking, maintenance, and light fabrication tasks.

## Long description

Proline 77630 is a single HSS metal drill bit with a 3 mm diameter and an overall length of 190 mm, supplied as one piece. Engineered for drilling steel, non-ferrous metals and plastics, this extra-long, fully ground bit provides straight and accurate holes when used in hand drills, drill presses or with drill bushes. The 135° point angle with chamfering adjustment enables fast penetration and reduces the need for repeated marking, while the high-quality refined HSS material ensures wear resistance and sustained cutting performance during light fabrication and maintenance tasks.
Advantages
The fully ground flute and extra length of this drill bit deliver high rectilinearity and consistent hole geometry over the full cutting depth. The 135° split point with chamfering adjustment reduces walking and improves centring on metal surfaces, allowing quicker start and reduced pilot drilling. Made from refined high-speed steel, the bit offers enhanced durability and heat resistance compared with standard carbon drills, making it suitable for repeated use in metalworking and for drilling in thin to medium-thickness sheets and profiles.
Suitable for
Drilling holes in steel sheets, profiles and metal components
Work with non-ferrous metals such as aluminium and brass
Light fabrication, maintenance and repair tasks
Drilling in plastics where straight, deep holes are required
Use with hand drills, drill presses and drill bushes

How to use
Secure the Proline 77630 drill bit in the chuck of a hand drill or a drill press, ensuring correct alignment and firm clamping. Select an appropriate rotational speed for the material being drilled—lower speeds for harder steels and higher speeds for softer non-ferrous metals and plastics. Use cutting fluid or coolant when drilling steel to reduce heat and extend tool life. Begin drilling with steady feed pressure, allowing the 135° point to self-centre; withdraw periodically in deeper holes to clear chips and avoid clogging. After use, clean the bit and store it in its case to protect the cutting edges.
Usage recommendations
For best results when drilling metal, use a backing support or clamp the workpiece to minimise vibration and improve hole accuracy. Match drill speed and feed to the material: moderate speed with steady feed is recommended for thin to medium-thickness steel, while increased speed and lighter feed suit aluminium and plastics. Regular application of cutting fluid will prolong bit life and improve hole finish.
