Cleveland M12×1.75 Straight Flute Tap

Suited for maintenance
Machinists creating new M12×1.75 threads in through or blind holes will find the 23.81 mm thread length effective. The D6 limit and 6H class of fit meet standard tolerance requirements. Builders needing a taper or plug chamfer for easier starting should select a different tap style.
10.30 mm drill size for 75 percent thread engagement
Preparing the hole with a 10.30 mm drill produces the recommended 75 percent thread depth before tapping. This single dimension determines whether the tap will cut correctly in your material..verify the drill size matches your workpiece before starting.

Questions about this item
What does the M12-1.75 thread size mean when I use this tap in a workpiece?
It cuts a metric M12 thread with a 1.75 mm pitch, producing a 6H class of fit when drilled with the recommended 10.30 mm drill.
What does the D6 thread limit and 6H class of fit cap in practice?
The D6 limit and 6H fit define the allowable pitch-diameter tolerance so the finished thread meets standard metric 6H gauge requirements.
What hole depth and shank clearance does the 85.72 mm overall length and 23.81 mm thread length require?
The 23.81 mm thread length sets the maximum full-thread depth, while the 85.72 mm overall length determines the shank clearance needed in your holder or chuck.
