Drill bit GEKO HSS for metal, model 38212

GEKO HSS drill bit for metal, model 38212 is a high-speed steel cutting tool engineered for drilling through a wide range of metal materials. Designed for use with standard drills and drill presses, this HSS bit delivers accurate hole-making in both ferrous and non-ferrous metals when used at appropriate speeds and with correct lubrication. The geometry and material of the bit are intended to provide reliable cutting performance and maintain edge integrity during general workshop, maintenance and DIY applications.

Advantages

The HSS construction offers good wear resistance and heat tolerance for metal drilling. A precise tip geometry helps to reduce walking at the start of a hole and improves centring. The drill bit is compatible with common drill chucks and provides consistent hole diameter and finish when used under recommended operating conditions. Its general-purpose design makes it suitable for a variety of metalworking tasks without requiring specialised equipment.

Suitable for

• Drilling holes in steel and cast iron
• Penetrating non-ferrous metals such as aluminium and copper
• Workshop repairs and maintenance
• DIY metal fabrication and assembly tasks

Key specifications

• Material: high-speed steel (HSS)
• Intended use: metal drilling (ferrous and non-ferrous)
• Compatibility: standard drill chucks and drill presses
• Typical operating requirements: appropriate cutting speed and lubrication for metal
• Finish: machined flutes for chip evacuation and consistent hole quality

How to use

Secure the workpiece and select a drill speed appropriate for the metal type and hole diameter. Fit the drill bit into the chuck and tighten securely. Apply a suitable cutting lubricant when drilling harder metals or larger diameters to reduce heat and wear. Start drilling at moderate pressure, keeping the drill perpendicular to the work surface, and withdraw occasionally to clear chips. After completing the hole, deburr edges if required.

Usage recommendations

For best results, use cooling or cutting fluid on steel and cast iron, reduce speed for harder alloys, and ensure the drill bit is clamped firmly in a clean chuck. Replace the bit if wear or chipping affects hole quality.
