  • Set includes taper, plug and bottoming taps

M3x0.5 Metric Hand Tap Set

This three-piece set contains taper, plug and bottoming taps for cutting M3x0.5 threads in through-holes and blind holes. Each tap is made from high-speed steel with a bright, uncoated finish and three straight flutes. The set suits general-purpose threading in ferrous and non-ferrous materials.

D3 Thread Limit for 6H Class of Fit

The taps are manufactured to a D3 thread limit, matching a 6H class of fit for standard metric applications. This single tolerance designation determines whether the finished thread will gauge correctly, making it the critical specification for selecting the right tool.

5/8 Inch Thread Length and 75 Percent Drill Size

Each tap provides a 5/8 inch thread length within an overall length of 1 15/16 inches, offering adequate reach for shallow holes. The recommended 75 percent thread drill size is 2.50 mm, which leaves sufficient material for strong threads in thin sections but may not suit deep-hole requirements.

Questions about this item

What does the M3x0.5 thread size mean when I use this tap set in a real machine?

The M3x0.5 designation means the tap cuts a 3 mm major diameter thread with a 0.5 mm pitch, producing a standard metric coarse thread suitable for matching M3 fasteners.

How does the D3 thread limit and 6H class of fit affect the threads this set produces?

The D3 limit and 6H fit class define the tolerance zone for the internal thread, ensuring the tapped hole accepts standard M3 bolts with the correct clearance and engagement.

What drill size and clearance do I need to fit this tap set properly?

Use a 2.50 mm drill for 75 percent thread engagement; the tap's overall length is 1 15/16 in with a 5/8 in thread length, so ensure your workpiece and holder accommodate those dimensions.
