M2x0.4 Straight Flute Hand Tap
This Greenfield Threading hand tap cuts internal M2x0.4 metric threads with a taper lead for easy starting. It is made from high-speed steel with a TiN coating for wear resistance. The 44.45 mm overall length and 11.11 mm thread length suit general-purpose threading tasks. Right-hand cutting direction matches standard fastener orientation.
Replaces worn or undersized M2 taps
Switch when an existing tap produces loose threads measured outside the 2B class of fit or when the D3 limit no longer holds tolerance. The 75 percent thread engagement with a 1.60 mm drill size restores full thread depth in through-holes. The taper chamfer helps alignment in materials where a bottoming tap would bind.
Consistent cutting under repeated use
High-speed steel substrate maintains edge geometry during extended hand-tapping cycles without the chipping risk of carbide. TiN coating reduces galling on stainless and carbon steels when lubrication is marginal. Straight flute design clears chips in short bursts rather than continuous flow, so frequent reversal clears the hole. Not suited for deep blind holes where chip evacuation space is limited.

Questions about this item
What tap drill size do I need for the M2x0.4 thread?
Use a 1.60 mm drill to produce the 75 percent thread depth before tapping.
How do I start the tap straight in the hole?
Apply steady axial pressure while turning the taper lead slowly; the 11.11 mm thread length engages gradually to prevent cross-threading.
When should I replace this high-speed steel tap?
Replace it when the TiN coating wears and the cutting edges no longer form clean threads in the 44.45 mm overall length.
