Drill Bit Set GEKO G02006 — 4–7 mm HSS twist drills, compatible with metal and wood

GEKO G02006 is a set of high-speed steel (HSS) twist drill bits covering sizes from 4 mm to 7 mm. These drills are intended for general-purpose drilling in metal, wood and some plastics, offering a balance between cutting performance and wear resistance. Delivered as a compact set, the bits suit both handheld drills and drill presses for repair, fabrication and light to medium-duty DIY tasks.

Advantages

The HSS material provides high hardness and heat resistance during intermittent drilling, helping maintain edge sharpness and extend service life. The spiral flute geometry evacuates chips efficiently, reducing clogging when working in metal and softer materials. The set format ensures the most commonly used medium diameters are available together, simplifying selection and storage.

Suitable for

• Drilling through mild steel and non-ferrous metals
• Woodworking, including soft and hardwoods
• Drilling in plastics and composite panels
• Home repairs, assembly and light fabrication tasks
• Use with handheld electric drills and benchtop drills

Key specifications

• Material: High-speed steel (HSS)
• Bit type: Twist drill
• Size range: 4 mm, 5 mm, 6 mm, 7 mm
• Shank style: Straight round shank for standard chucks
• Typical applications: Metal, wood, plastics

How to use

Select the appropriate diameter for the hole required and secure the bit tightly in the drill chuck. For metal drilling, mark the center and consider a centre punch to prevent walking. Use appropriate cutting speed and steady feed; reduce speed and apply cutting fluid when drilling tougher metals to limit heat buildup. For wood and plastics, use moderate speeds and clear chips from the hole periodically. Maintain steady pressure and avoid excessive force that can break medium-diameter bits.

Usage recommendations

For best results, match drilling speed to the material: higher speeds for wood and plastics, lower speeds with lubricant for metals. Inspect bits for wear or damage before use and replace them when edges become blunt to ensure clean holes and safe operation.
