Drill bit set GEKO G39750 for spot welds — 3 pcs: 6.5 mm, 8 mm, 10 mm

The GEKO G39750 drill bit set for spot welds contains three round high-speed steel bits with diameters of 6.5 mm, 8 mm and 10 mm. Designed for controlled removal of spot welds and for work on sheet metal joints, this compact set is compatible with standard drill drivers and is intended for workshop and automotive repair tasks where accuracy and repeatability are required.

Advantages

The set provides three commonly used diameters that cover a range of spot weld sizes, reducing the need to change tools during repair work. Made from heat-treated high-speed steel, the bits offer wear resistance and maintain cutting performance when used with appropriate speeds and cooling. Their round-shank design fits typical drill chucks, enabling quick installation and reliable centring during drilling.

Suitable for

• Removing spot welds on car body panels and sheet metal assemblies
• Automotive body repair and panel replacement preparation
• General sheet metal work in workshops and fabrication garages
• Applications requiring controlled, repeatable hole sizes for weld removal

When it may not be suitable

This drill bit set is intended for drilling out spot welds and light to medium sheet metal tasks; it is not designed for heavy structural steel or continuous production drilling of thick materials. For hardened or excessively thick materials, specialized bits or pre-drilling techniques may be necessary. Use appropriate protective equipment and clamps when working on thin panels to avoid deformation.

Key specifications

• Set composition: 3 round drill bits
• Diameters: 6.5 mm, 8 mm, 10 mm
• Material: high-speed steel (heat-treated)
• Shank type: round shank compatible with standard drill chucks
• Intended use: spot weld removal and sheet metal drilling

How to use

Select the bit size appropriate for the spot weld diameter, secure the workpiece to prevent movement, and install the bit in a drill with a suitable chuck. Start drilling at low to moderate speed to locate and remove the weld material, applying steady pressure and withdrawing periodically to clear chips. If necessary, reduce speed and use light lubrication or cooling when drilling multiple welds to maintain bit life. After removing the weld, inspect the hole and clean burrs before further welding or fitting replacement panels.

What to consider before purchase

• Verify that the diameters (6.5 mm, 8 mm, 10 mm) match the spot weld sizes you commonly encounter
• Confirm your drill’s chuck accepts round shank bits and can maintain stable rotation at recommended speeds
• Consider whether high-volume or heavy-duty applications require industrial or coated variants

Usage recommendations

Use the 6.5 mm bit for smaller spot welds and the 10 mm bit for larger welds or when access requires a wider removal hole. Keep drill speed moderate, secure thin panels to prevent distortion, and replace bits when cutting performance declines to ensure consistent results.
