## Summary description

Proline HSS cylindrical drill bit for metal, 18.5 mm diameter (model ZR76185). Made from high-speed steel (HSS) for drilling steel and other metals, this straight-shank bit is intended for use with handheld drills and drill presses. Suitable for through and blind holes in fabrication, maintenance and repair, and metalworking projects.

## Long description

The Proline HSS cylindrical drill bit for metal, 18.5 mm diameter, is a straight-shank cutting tool designed for drilling steel and other ferrous and non-ferrous metals. Manufactured from high-speed steel (HSS), the bit provides a balance of hardness and toughness suited to common workshop and industrial drilling tasks. Its cylindrical shank fits standard chucks on handheld drills and drill presses, enabling use in both portable and stationary equipment for through and blind hole applications in fabrication, maintenance and repair, and general metalworking.
Advantages
The high-speed steel construction offers wear resistance and retains cutting edge hardness at typical drilling temperatures, allowing reliable performance when drilling medium-hard metals. The straight cylindrical shank ensures secure chucking and straightforward alignment in both hand drills and drill presses. The 18.5 mm diameter is useful for medium-to-large hole requirements where strength and rigidity are needed to reduce deflection during cutting. The simple, single-piece design minimises vibration and facilitates straightforward sharpening when required.
Suitable for
Drilling through holes and blind holes in steel plates and metal components
Workshop fabrication and assembly tasks
Maintenance and repair operations on machinery and structures
Use with handheld electric drills and drill presses
Key specifications
Material: High-speed steel (HSS)
Diameter: 18.5 mm
Shank type: Cylindrical / straight shank for standard chucks
Intended use: Metal drilling (ferrous and non-ferrous)
Suitable hole types: Through holes and blind holes
How to use
Secure the drill bit in the chuck of a handheld drill or drill press, ensuring proper centring and tight clamping. Select an appropriate rotational speed and apply steady feed pressure according to the metal being drilled—slower speeds for harder steels, higher speeds for softer alloys. Use cutting fluid or lubricant to reduce heat and improve tool life when drilling steel. Withdraw periodically to clear chips when making deep holes, and check hole size and alignment as you progress.
Usage recommendations
For best results, use a quality cutting fluid and moderate speed to extend bit life. When drilling hardened steels or working at high temperatures, consider pre-drilling with smaller pilot sizes and perform finishing passes as needed. Inspect the cutting edges periodically and resharpen or replace the bit when wear or chipping affects hole quality.
