Tap drill set GEKO HSS M3–M10, 6 pieces

GEKO HSS tap and drill set M3–M10, 6 pieces, contains high-speed steel taps and matching drills designed for producing internal metric threads from M3 to M10. The tools are suitable for manual tapping and machine tapping operations in a range of materials normally compatible with HSS tooling, including soft steels, non-ferrous metals and some plastics. The set is intended for repair, maintenance and general metalworking tasks where reliably formed internal threads are required.

Advantages

The GEKO HSS set provides a compact selection of taps and drills that cover common metric sizes M3 through M10, reducing the need to source individual tools. High-speed steel construction offers a balance of hardness and toughness for typical workshop applications and supports repeated use under normal cutting conditions. The combination of taps with their matching drill sizes simplifies preparation of holes for accurate thread cutting and consistent thread quality.

Suitable for

• Cutting internal metric threads M3, M4, M5, M6, M8 and M10
• Repair and maintenance of machinery and equipment
• General metalworking and fabrication tasks
• Manual tapping and use in drilling/tapping machines
• Threading in soft steels, non-ferrous metals and suitable plastics

Key specifications

• Material: high-speed steel (HSS)
• Thread range: metric M3 to M10
• Number of pieces: 6 (set covering standard metric sizes M3, M4, M5, M6, M8, M10)
• Application: internal thread cutting for manual or machine tapping
• Compatibility: suitable for use on metals and other materials compatible with HSS tools

How to use

Select the appropriate tap and corresponding drill size for the desired thread size. Drill a hole to the recommended diameter for the chosen thread, keeping the drill perpendicular to the workpiece. When tapping manually, use a tap wrench and apply steady, even pressure while turning; advance one full turn and then reverse a small fraction to break chips. For machine tapping, secure the workpiece and set appropriate spindle speed and feed for the material. Use cutting fluid where appropriate to prolong tool life and improve chip evacuation. After cutting, clean the threads and inspect for correct form and fit.

Usage recommendations

Use suitable cutting fluid for metal applications, maintain correct drill-to-tap alignment, and avoid excessive feed or speed to prevent premature wear or tap breakage. Store the set in a dry place to prevent corrosion and inspect taps before use for any damage.
