## Summary description

Proline HSS cylindrical drill bit 15.5 mm designed for drilling metal. Made from high-speed steel (HSS), it provides wear resistance and suitable cutting performance for steel and non-ferrous metals. Cylindrical shank fits standard chucks and is intended for use in hand drills and drill presses for maintenance, fabrication, and mechanical work.

## Long description

Proline HSS cylindrical 15.5 mm drill bit model 76155 is designed for drilling metal. Manufactured from high-speed steel (HSS), this drill bit balances hardness and toughness to provide consistent cutting performance in steel and non-ferrous metals. The straight cylindrical shank is compatible with standard chucks on hand drills and drill presses, making it suitable for workshop maintenance, fabrication tasks and general mechanical work.
Advantages
The HSS material offers good wear resistance and heat tolerance during intermittent drilling, helping to maintain cutting edge geometry. The cylindrical shank ensures secure clamping in most standard drill chucks without requiring an adapter. Its 15.5 mm diameter provides a mid-range hole size useful for a variety of metalwork applications, enabling precise hole-making with appropriate drilling speed and lubrication.
Suitable for
 Drilling mild and medium-hard steels
 Holes in non-ferrous metals such as aluminum and brass
 Maintenance and repair tasks in workshops
 Fabrication work on metal components
 Use with hand drills and drill presses
Key specifications
 Material: High-speed steel (HSS)
 Shank type: Cylindrical straight shank for standard chucks
 Drill diameter: 15.5 mm
 Intended use: Metal cutting (steel and non-ferrous metals)
 Suitable equipment: Hand drills and bench drill presses
How to use
Secure the drill bit in the chuck ensuring proper alignment and tight clamping. Select an appropriate drill speed for the material being worked—slower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply cutting fluid or lubricant when drilling steel to reduce heat and prolong tool life. Drill with steady feed pressure, withdraw periodically to clear chips, and keep the workpiece clamped to prevent movement.
Usage recommendations
For best results, match drilling speed and lubrication to the metal type, maintain correct chip evacuation, and inspect the cutting edge for wear. Replace the bit once accuracy or cutting performance degrades to avoid damage to the workpiece.
