Tap drill set GEKO HSS M3–M10 6 pcs, hex shank (20/100)

GEKO HSS tap drill set M3–M10 6 pcs with hex shank is a compact toolkit designed for cutting or repairing internal metric threads in a variety of machinable materials. The set includes six taps covering sizes from M3 to M10 made from high-speed steel (HSS), offering general-purpose performance and wear resistance suitable for workshop use. Each tap features a hex shank compatible with quick-change holders, driver bits, or drill chucks that accept hex shanks, simplifying tool changes and reducing setup time.

Advantages

The taps are manufactured from HSS, providing a balance of hardness and toughness for cutting threads in metals, plastics and similar materials. The hex shank design enables fast insertion into compatible holders and reduces the need for additional adapters. Supplied as a coordinated set of six taps, the kit covers common metric thread sizes from M3 to M10, allowing a single set to serve multiple repair and fabrication tasks. The compact presentation supports organized storage in a workshop environment.

Suitable for

• Cutting or repairing internal metric threads in steel, aluminium and non-ferrous metals
• Threading in plastic components and composite materials
• General maintenance, repair and fabrication in workshops and garages
• Quick-change operations using hex-shank compatible holders or bit chucks

Key specifications

• Thread sizes covered: M3, M4, M5, M6, M8, M10
• Material: High-speed steel (HSS)
• Shank type: Hex (HEX) shank for quick-change holders
• Set composition: 6 taps in one compact set
• Application: Internal metric threading for general-purpose use

How to use

Select the tap size that matches the intended thread. Secure the workpiece and drill an appropriate pilot hole for the chosen thread size using the recommended drill bit diameter for the material and thread. Mount the tap by placing its hex shank into a compatible quick-change holder, bit chuck or driver. Align the tap with the hole and apply steady pressure while turning clockwise to cut the thread; reverse periodically to clear chips. Use cutting fluid where appropriate for metal to improve thread quality and tool life. After threading, clean the hole and remove chips before assembly.

Usage recommendations

For best results, match pilot hole diameter to the thread size and material, use appropriate cutting lubricant when machining metals, and avoid excessive force to reduce risk of tap breakage. When working with brittle materials, proceed slowly and clear chips frequently to prevent clogging.
