Greenfield Threading M3.5 Tap Set

This three-piece hand tap set cuts M3.5 x 0.60 metric threads in a single operation. It suits mechanics and machinists who need to create or repair internal threads in maintenance or light production work.

HSS Bright Uncoated Threading Limits

High-speed steel construction with a bright uncoated finish handles general-purpose materials but wears faster in abrasive or high-alloy stock. The D4 thread limit and 6H class of fit define the tolerance window, so holes outside this range will not gauge correctly.

Straightforward Installation With Common Risks

The 11/16 inch thread length and 2 inch overall length fit standard tap wrenches and holders. Misalignment during starting, insufficient lubrication, or forcing the bottoming tap too deep are the typical causes of broken flutes or oversized threads.

Questions about this item

Should I use the taper, plug or bottoming tap first for an M3.5x0.60 thread?

Start with the taper tap to begin the thread, follow with the plug tap for deeper engagement, and finish with the bottoming tap to reach the bottom of a blind hole.

What does the 11/16 inch thread length mean when I am tapping a hole?

The cutting portion of each tap is 11/16 inch long, so you can cut threads up to that depth in a single pass before clearing chips.

What does the D4 thread limit on these metric taps control?

The D4 limit sets the pitch-diameter tolerance so the finished M3.5x0.60 thread meets the 6H class of fit for a standard right-hand metric hole.
