Drill Bit Set GEKO G38215 – twist bits for metal 1–13 mm, 25 pieces

GEKO G38215 is a 25-piece twist drill bit set designed specifically for drilling metal. The set includes silver-coloured high-speed steel bits covering a continuous range of sizes from 1 mm to 13 mm, supplied in a compact case for storage and transport. These bits are suitable for use in handheld drills and drill presses and are intended for tasks that require reliable, straight holes in steel, iron and similar ferrous and non-ferrous metals.

Advantages

The set provides a broad size range so you can select the exact diameter needed for pilot holes, clearance holes or fastening operations. Bits are made for metalworking, offering consistent geometry for efficient cutting and chip evacuation. The compact case organises all 25 pieces by size for quick access and safe storage. The silver finish indicates general-purpose high-speed steel suitable for a wide variety of workshop and maintenance tasks.

How to use

Select the correct drill bit diameter for the required hole. Secure the workpiece and use appropriate clamping to prevent movement. Fit the chosen twist bit into the drill chuck and tighten securely. Use moderate drilling speed and steady feed for small diameters; reduce speed and increase pressure for larger diameters when drilling hard metals. Apply cutting fluid or lubricant when drilling steel to reduce heat and improve chip removal, and periodically withdraw the bit to clear chips. After use, clean the bits and return them to the case to maintain organisation and protect cutting edges.

Usage recommendations

For best results when drilling steel or iron, use a suitable cutting lubricant, maintain correct speeds for each diameter, and ensure the bit is sharp and properly aligned in the chuck. Wear appropriate personal protective equipment such as safety glasses and gloves when drilling.
