Drill bit Proline 71630, metal drill bit Ø16 mm, length 300 mm, 1 pc

Proline 71630 is a single solid metal drill bit with a 16 mm diameter and a total length of 300 mm, supplied as one piece for use in bench or hand-held drilling machines. Designed for metalworking and professional applications, this drill bit is intended for drilling through metal and similar materials in workshop and construction tasks. The tool combines a long working length with a robust solid design to reach deeper holes while maintaining rigidity during drilling.

Advantages

The solid construction provides improved strength and stability when drilling into metal, reducing the risk of breakage under load. The 300 mm overall length allows access to deeper workpieces without changing tools. Optimised cutting geometry promotes efficient chip evacuation and steady cutting, helping to maintain hole accuracy and prolong bit life. Supplied as a single piece, the bit is ready for immediate installation and use in standard chucks of drilling machines.

Suitable for

• Drilling through metal plates and structural steel
• Workshop and industrial maintenance tasks
• Hand-held and bench drilling machines
• Construction tasks requiring deep or hard-to-reach holes in metal

Key specifications

• Material application: metal and similar materials
• Diameter: 16 mm
• Total length: 300 mm
• Type: solid single-piece drill bit
• Suitable for: bench and hand-held drilling machines
• Cutting geometry: 4-blade insert with optimised geometry

How to use

Secure the drill bit in the chuck of a compatible drilling machine, ensuring proper centring and tight clamping before operation. Select an appropriate rotational speed and feed rate for the metal being drilled, and use cutting fluid or coolant where applicable to reduce heat and wear. Apply steady pressure and allow the tool to cut without excessive force; withdraw periodically to clear chips if drilling deep holes. After use, clean and store the bit dry to minimise corrosion.

Usage recommendations

For best results when drilling metal, use appropriate cutting fluid, select speed and feed matched to the material, and ensure the drill is properly clamped. For deep holes, periodically retract the bit to evacuate chips and prevent jamming.
