Metric M2×0.4 Straight Flute Hand Tap

This Greenfield Threading CHICAGO-LATROBE 328685 is a plug-style straight flute hand tap cut for M2×0.4 metric threads. It is made from high-speed steel with a TiN coating and has a right-hand cutting direction. The tool suits mechanics and technicians who need to create internal threads by hand in metal components.

For manual thread cutting in small diameters

It fits users who cut threads by hand with a tap wrench and require a plug chamfer for through-hole or deep-hole work. Builders who need machine taps, spiral-point taps, spiral-flute taps or taps for larger thread sizes should look at other tooling. The D3 thread limit and 2B class of fit also mean it is not suited for applications demanding tighter or looser tolerance classes.

TiN coating extends tool life

The titanium nitride coating reduces friction and wear, allowing more holes per tap before resharpening or replacement. This lowers consumable cost and downtime on repetitive threading jobs. No additional accessories or software are bundled with the tap.
