The titanium-coated surface dramatically extends tool life and reduces friction during tapping, giving you professional results whether you're a hobbyist or a seasoned metalworker.

Made in Mainland China.

Key Features

• Titanium Coating: Hard, wear-resistant surface finish for longer tool life and smoother thread cutting.
• Spiral Flute Design: Efficiently evacuates chips from the hole, reducing clogging and improving cut quality.
• Right-Hand Thread Direction: Standard metric right-hand thread for universal compatibility.
• Wide Size Range: Available in M3, M4, M5, M6, and M8 — select the size you need.
• Versatile Material Compatibility: Works on wood, iron, aluminum, thin stainless steel, and other common materials.
• High-Speed Steel (HSS) Construction: Delivers outstanding hardness and heat resistance for demanding tapping applications.

How to Use

1. Align the tap: Insert the tap so its centerline is perfectly aligned with the centerline of the pre-drilled hole.
2. Start tapping: Rotate evenly with both hands and apply gentle, steady pressure to feed the tap in. Once cutting begins, no additional pressure is needed.
3. Break chips regularly: Reverse the tap approximately 45° after every full turn to break and clear chips, preventing clogging.
4. Don't force it: If the tap becomes difficult to rotate, stop and back it out slightly to clear chips. Forcing the tap risks breakage.

Frequently Asked Questions

Q: What materials can this HSS spiral flute tap be used on?

A: This titanium-coated HSS tap is suitable for tapping threads in wood, iron, aluminum, thin stainless steel, and other common materials. It is not recommended for hardened steel or very thick stainless steel without proper cutting fluid.

Q: What is the difference between a spiral flute tap and a standard tap?

A: A spiral flute tap features helical flutes that actively pull chips up and out of the hole during tapping, much like a drill bit. This makes it especially effective in blind holes and softer materials where chip evacuation is important, resulting in cleaner threads and fewer tap breakages compared to straight-flute taps.

Q: Do I need cutting fluid when using this metric thread tap?

A: While the titanium coating reduces friction, using a suitable cutting oil or tapping fluid is always recommended — especially when working with metals like iron or stainless steel. Cutting fluid helps dissipate heat, extends tool life, and produces smoother, more accurate threads.

Q: Which size should I pre-drill before using this tap?

A: Use the standard tap drill size for each metric thread: M3 → 2.5mm, M4 → 3.3mm, M5 → 4.2mm, M6 → 5.0mm, M8 → 6.8mm. Always pre-drill with the correct pilot hole size for best threading results.
