FAQs
Can I use these taps with a hand drill?
No. These are machine taps designed for CNC, milling, or tapping machines. Using them with hand tools will cause the tap to break.
What material is this tap made of?
These taps are manufactured from high-speed steel (HSS), chosen for its excellent hardness and wear resistance.
Do I need to use oil with this tap?
Yes. Applying tapping oil is highly recommended to improve the quality of the threads, reduce heat, and increase the lifespan of the tool.
Can I use these on stainless steel?
Yes, these taps are suitable for stainless steel, as well as iron, copper, zinc, and alloy steel.
Is this a through-hole or blind-hole tap?
This tap is specifically designed for through-holes or shallow holes where chip removal is facilitated by the flute geometry.
What size is this tap?
This is an M4 metric coarse thread tap.
Troubleshooting
Tap breaks during use
Verify that the machine feed rate matches the tap pitch and ensure the workpiece is rigid and vibration-free.
Threads appear rough or have burrs
Increase the amount of tapping oil used and verify that the cutting speed is appropriate for the material hardness.
Difficulty starting the thread
Ensure the pilot hole is correctly sized for an M4 tap and that the machine spindle is perfectly aligned with the hole center.

Setup, Compatibility & Care
To ensure the longevity of your M4 taps, always secure the workpiece firmly in a vice or fixture to prevent vibration, which can lead to tap breakage. These taps are strictly intended for machine use—attempting to use them with a hand tap wrench or a handheld drill will likely result in misalignment and structural failure of the tool. When installing, ensure the tap is perfectly perpendicular to the surface. Always apply a generous amount of tapping oil before starting the cycle to reduce friction and clear away fine metal shavings. After use, wipe the tap clean with a lint-free cloth and apply a light coat of machine oil before storing in a dry environment to prevent corrosion.
