M12 x 1.5 Metric Thread Tap

This straight flute hand tap cuts M12 threads with a 1.5 mm pitch for metric fastening work. It is made from high speed steel with a bright uncoated finish and a right hand thread direction. The taper chamfer eases starting in through holes or deep blind holes. Machinists and maintenance technicians use it for general purpose threading in steel and non ferrous metals.

Thermal Noise And Power In Normal Use

Hand taps generate negligible heat and noise because they are turned manually or with low speed machines. No electrical power is drawn and no cooling system is required during operation. Cutting fluid can reduce friction and extend tool life when threading tougher materials. The bright finish shows wear visually without coated surface masking.

Bright Finish And D6 Limit Benefits

The uncoated bright finish allows easy inspection of cutting edges and resharpening when needed. A D6 thread limit with a 2B class of fit provides standard tolerance for general assembly work. The 1.66 inch thread length and 3.38 inch overall length suit common hole depths. Users needing tighter limits or coated performance for high volume production should select a different tap.

Questions about this item

How do I start the M12 x 1.5 taper tap straight in a drilled hole?

Drill the correct tapping size hole, apply cutting fluid, and start the taper tap by hand with a tap wrench, keeping it perpendicular so the 1.66 in thread length cuts cleanly.

When will the high-speed steel tap need replacement?

Replace the tap when the four flutes show rounded crests, chips no longer clear, or the D6 limit threads no longer gauge to a 2B fit.

What limits how many M12 holes I can tap continuously?

Heat buildup in the uncoated high-speed steel and chip packing in the 1.66 in thread length are the first limits under sustained use.
