Drill bit Proline 71654, HSS metal, Ø16 mm, length 540 mm, 1 pc

Proline 71654 is a high-speed steel (HSS) drill bit designed for metalworking and other demanding drilling tasks. With a nominal diameter of 16 mm and an overall length of 540 mm, this single-piece bit provides extended reach for drilling larger-diameter holes in metal and hard materials. It is intended for use in compatible drill chucks in workshop and industrial settings where precision and a long working reach are required.

Advantages

The Proline HSS construction offers material hardness and heat resistance suitable for sustained metal drilling. Its extended 540 mm length allows access to recessed or deep workpieces without the need for extensions. The 16 mm diameter provides a stable cutting profile for producing clean, consistent holes. Supplied as a single unit, the bit is ready for immediate installation in standard chucks that accept the shank type for this diameter and application.

Suitable for

• Drilling through steel and non-ferrous metals
• Long-reach holes in workshop and industrial environments
• Applications requiring a 16 mm hole diameter
• Use with compatible hand-held and bench drills

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 16 mm
• Overall length: 540 mm
• Quantity: 1 piece
• Intended use: Metalworking and hard material drilling

How to use

Fit the drill bit securely into a compatible drill chuck, ensuring adequate clamping length and concentricity. Select an appropriate cutting speed and feed rate for the workpiece material to avoid overheating; for harder metals reduce speed and use steady, controlled feed. Apply cutting fluid or lubricant when drilling ferrous metals to improve heat dissipation and prolong tool life. Clear chips regularly during deep drilling to prevent clogging and maintain cutting efficiency.

Usage recommendations

For best results, use the Proline HSS 16 mm bit with drills capable of maintaining stable RPM under load and with a suitable chuck clamping range. When drilling deep holes, periodically retract the bit to evacuate chips and apply cutting fluid. Avoid excessive side loads to prevent bending and premature wear.
