M12 x 1.75 Metric Hand Tap
The Greenfield Threading 313522 is a straight-flute hand tap for cutting M12 threads with a 1.75 mm pitch. It suits mechanics, fabricators and maintenance crews who need to create new internal threads or clean damaged ones in steel and similar materials.
42.06 mm Thread Length and 75 % Drill Size
The tap cuts a 42.06 mm long thread and requires a 10.30 mm drill for a 75 percent thread depth. Its three-flute high-speed steel body provides chip clearance in through-holes, but the straight-flute design limits evacuation in deep blind holes.
Plug Chamfer and D11 Thread Limit
The plug chamfer starts threads easily in through-holes and the D11 limit produces a 6H class fit. Buyers who need a bottoming chamfer for blind holes or a tighter thread class should select a different tap.

Questions about this item
Will the 10.30 mm drill size work with my existing M12 tap set?
The 75 percent thread drill size is 10.30 mm, matching standard M12-1.75 preparation, so your current drill bits for this thread should be compatible.
How can I verify the 313522 tap is cutting correctly after setup?
Check that the straight-flute, three-flute tap produces clean threads at the 42.06 mm thread length with a 6H class of fit in the workpiece.
Does the 313522 package include a 10.30 mm drill bit or only the tap?
The box contains the M12-1.75 plug tap with 85.73 mm overall length; a 10.30 mm drill bit must be purchased separately.
