Proline 71635 — metal drill bit Ø16 mm, length 350 mm, 1 pc is a single high-reach drill bit designed for drilling metal. With a nominal diameter of 16 mm and an overall length of 350 mm, this Proline bit is intended for applications where extended reach is required, including workshop, construction and maintenance tasks. The product is supplied as one piece and is compatible with handheld drills and drill presses capable of accepting 16 mm shanks or appropriate chucks.

Advantages

The Proline 71635 drill bit provides a long working length that allows deeper or through-hole drilling in metal without frequent repositioning. Its 16 mm diameter offers a stable hole size for fastening and fitting operations. Supplied as a single unit, it is convenient for targeted repairs or one-off jobs where a longer-than-standard bit is needed. The design supports use in both portable and bench-mounted drilling equipment, offering flexibility for varied metalworking tasks.

Suitable for

• Drilling deep or through holes in metal plates and profiles
• Workshop and maintenance drilling tasks requiring extended reach
• Use with handheld drills and drill presses when longer bit length is necessary
• Pilot holes or clearance holes for bolts and fasteners in metal assemblies

Key specifications

• Diameter: 16 mm
• Overall length: 350 mm
• Quantity: 1 piece
• Material compatibility: designed for drilling metal
• Intended use: suitable for handheld drills and drill presses

How to use

Select an appropriate chuck or adapter to secure the 16 mm drill bit in your handheld drill or drill press. Mark the drilling point and, if necessary, clamp the workpiece to prevent movement. Start drilling at low speed to establish the hole, then increase speed gradually while maintaining steady pressure and cooling as needed for the metal type. Retract the bit occasionally to clear chips and prevent overheating. After completing the hole, remove burrs or sharp edges as required for the application.

Usage recommendations

For extended life and consistent performance, use cutting fluid or coolant when drilling thicker metal sections, maintain moderate drilling speeds appropriate for the metal grade, and ensure the drill bit is securely clamped in the chuck. If precise hole alignment is critical, use a pilot hole or centre punch before drilling.
