## Summary description

Proline 77165 metal drill bit, single piece with a diameter of 16.5 mm and overall length 184 mm.

## Long description

Proline 77165 metal drill bit Ø16.5 mm, length 184 mm, single piece for metal drilling applications. Made from refined HSS and produced entirely by grinding, this solid drill bit is designed to deliver straight, precise holes with improved abrasion resistance and enhanced torsional strength. The 135° point angle with chamfering adjustment supports quick penetration and reduces the need for extensive centre punching. Supplied as one unit in a protective plastic tube, the bit is suitable for workshops, fabrication, maintenance and repair tasks requiring a medium-large hole in metal.
Advantages
The fully ground construction ensures high dimensional accuracy and straightness of drilled openings, giving greater efficiency than standard cylindrical drills. The refined HSS material increases resistance to wear and improves resilience under load, while the 135° point angle with chamfering adjustment enables faster drilling and better centring. Increased torsional strength reduces breakage risk during heavy-duty use. The single-piece supply in a protective plastic tube simplifies storage and transport.
Suitable for
 Drilling medium-large holes in steel and other ferrous metals
 Workshop fabrication and metalworking tasks
 Maintenance and repair operations requiring Ø16.5 mm holes
 Use with hand-held and bench drilling machines with compatible chucks

How to use
Secure the drill bit in a compatible chuck and ensure it is firmly tightened before use. Select a drilling speed appropriate for the metal type and thickness; lower speeds are generally recommended for harder steels to reduce heat build-up. Use suitable cutting fluid or lubricant to extend tool life and improve chip evacuation. Start drilling with light pressure to establish a centre, then apply steady feed until the required depth is reached. Withdraw the bit periodically to clear chips and prevent clogging.
Usage recommendations
For best results, match drill speed and cutting fluid to the workpiece material, maintain firm chuck grip, and avoid excessive side loads. Inspect the bit for wear before use and replace it when edges become dull to maintain hole quality and reduce risk of breakage.
