Threading Tap Set Smart365 1/4" HSS M3–M10, 6 pcs

Smart365 Threading Tap Set 1/4" HSS M3–M10, 6 pcs is a compact kit of high-speed steel hand taps with a 1/4" shank designed for cutting internal metric threads from M3 to M10. The set is intended for manual tapping with a tap wrench or for use with power holders that accept a 1/4" shank. The taps are suitable for machining a range of materials typically encountered in maintenance, repair and fabrication tasks, providing a practical solution where a small, versatile thread-cutting kit is required.

Advantages

The kit provides six commonly used metric sizes in a single, space-saving package, reducing the need to buy individual taps. High-speed steel construction offers wear resistance and maintains cutting performance at typical hand-tapping speeds. The 1/4" shank format allows compatibility with many tap wrenches and quick-change power holders, making the set adaptable for both manual and powered operations. The uniform shank diameter simplifies storage and mounting.

Suitable for

• Creating or repairing internal threads in steel, aluminum and other machinable metals
• Maintenance and repair work on machinery, housings and fittings
• Small-scale fabrication and DIY projects requiring metric threads from M3 to M10
• Use with tap wrenches, ratchet tap holders or power tool adapters accepting 1/4" shank

Key specifications

• Material: high-speed steel (HSS)
• Shank diameter: 1/4"
• Thread sizes included: M3, M4, M5, M6, M8, M10
• Number of pieces: 6
• Application: internal metric thread cutting (hand or powered holders)

How to use

Select the tap matching the desired metric thread size and secure the tap in a compatible tap wrench or power holder with a 1/4" shank. Center the tap on the hole to be threaded, apply suitable cutting fluid, and start cutting with steady, controlled rotation. For hand tapping, advance in full turns and periodically reverse slightly to break chips. When using a powered holder, use low speed and light feed to avoid overloading the tap. Clean chips from the hole and inspect the thread for correct fit after cutting.

Usage recommendations

Use appropriate cutting fluid for the workpiece material, clamp the work securely, and choose the correct drill size for the tapped hole to achieve accurate thread profiles and prolong tap life.
