Product Identity

The Cleveland C54676 is a straight flute hand tap designed to cut M12x1.25 metric threads. It is intended for mechanics and machinists who need to create internal threads by hand. The tool is made from high speed steel with a bright uncoated finish. It features a right hand thread direction and a D5 thread limit for a 6H class of fit. The plug chamfer suits through holes or deeper blind holes.

Installation Notes

The tap requires a 10.78 mm drill size to achieve the recommended 75 percent thread engagement. Users must ensure the hole is drilled to this diameter before tapping. Proper lubrication and alignment are essential to avoid tap breakage or oversized threads. The overall length is 85.72 mm with a 42.07 mm thread length, so verify the workpiece depth accommodates the tool.

Suitability

This tap suits maintenance and repair tasks where M12x1.25 threads are specified and machine tapping is not available. It is not suited for high volume production threading or for materials that require coated or spiral point taps for chip evacuation. Buyers needing different thread pitches, diameters, or tap styles such as bottoming or spiral flute should look at other options.

Questions about this item

How can I confirm the C54676 tap is cutting threads correctly after setup?

Check that the M12 x 1.25 threads match a 6H class-of-fit gauge and that the thread length reaches the specified 42.07 mm depth.

What comes in the box with the C54676 tap and what must I purchase separately?

The box contains the straight-flute hand tap only; a 10.78 mm drill bit for the 75 percent thread drill size and a tap wrench are not included.

Which version of the Cleveland M12 tap should I choose for a through-hole job?

Select the plug-chamfer version (C54676) because its plug design is intended for through-hole threading in metric M12 x 1.25 applications.
