M3-0.50 Metric Tap Set
This three-piece hand tap set from Chicago-Latrobe covers M3 threads with a 0.50 mm pitch. It includes taper, plug and bottoming taps made from high-speed steel with a bright finish. The right-hand threads conform to a 6H class of fit and a D3 thread limit. Machinists and maintenance technicians use it for creating or repairing internal threads in metal components.
Three Taps for Complete Thread Depth
The taper tap starts the thread, the plug tap continues it and the bottoming tap finishes to the bottom of a blind hole. Each tap has three flutes, a thread length of 5/8 in and an overall length of 1 15/16 in. The set requires a suitable tap wrench and cutting fluid, which are not included. It frees the user from switching between separate single taps during a job.
Replaces Worn or Missing Single Taps
This set upgrades a workshop that relies on mismatched or dull individual taps for M3 work. The jump is worth it when a project demands consistent thread quality across through-holes and blind holes alike. Buyers needing larger diameters, different pitches or left-hand threads will need a separate set.

Questions about this item
How does the D3 thread limit affect thread fit when cutting M3 x 0.50 holes all day?
The D3 limit produces a 6H class of fit, giving a standard tolerance band for general-purpose metric threads in most materials.
Do the bright uncoated HSS taps run hot or load the drill motor during long tapping sessions?
Bright HSS generates more friction than coated taps, so cutting fluid and proper speed are needed to control heat and motor load.
What tap wrench or holder fits the 1 15/16 in overall length and 5/8 in thread length of these taps?
Any adjustable tap wrench or T-handle that accepts the standard square on M3 hand taps will engage these tools securely.
