Key specifications

 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.
