Cleveland C98144 Spiral Flute Tap

The Cleveland C98144 is a spiral flute tap designed for creating M12x1.25 metric threads in a variety of materials. Its semi-bottoming configuration and three-flute geometry suit machinists and maintenance technicians who require reliable internal threading performance.

Thermals Noise and Power Draw

As a non-powered hand tool accessory, this tap generates no operational heat, noise, or electrical power draw during use. Performance depends entirely on the driving machine and cutting parameters selected by the operator for the specific application.

Cobalt Construction and Black Oxide Finish

The cobalt substrate provides enhanced hardness and wear resistance compared to standard high-speed steel taps. A black oxide finish helps retain cutting fluid and reduces galling, extending tool life when threading stainless steel or other tough alloys.

Questions about this item

How do I install this M12x1.25 spiral flute tap without breaking it?

Use a proper tap wrench, keep the tap perpendicular to the workpiece, apply steady pressure with cutting fluid, and reverse frequently to clear chips from the 3 flutes.

When will this cobalt tap need replacement?

Replace when threads show excessive wear, chipping on the 3 flutes, or when the 6H class of fit can no longer be held in the M12x1.25 thread profile.

What limits continuous tapping with this 110 mm overall length tool?

Heat buildup in the cobalt body and chip packing in the 40 mm thread length are the first limits during sustained use.
